Subject: [MSA-talk] interplay between mineral reactions and deformation-
workshop
Message-ID: <016101d27c7d$a9710bc0$fc532340$@gmail.com>
dear friends and colleagues,
we would like to organize an informal workshop focused on the interplay
between mineral reactions and deformation. this workshop should be composed
of short talks followed by the fruitful fully interactive discussions on
this topic.
our aim is to create a brain-storming session that would cover all kinds of
views of this topic including theoretical formulations, experiments, from
microstructural to large scale direct evidences and numerical simulations.
we also aim to bring together senior scientists as well as motivated
students with conventional and unconventional-views to discuss where we are
now with our knowledge related to this topic, what are the weak points and
what is still missing and agree on some direction which this field should go
in future.
since we would like to encourage also non-european participants, we were
thinking about possible dates close to the goldschmidt and eclogite
conferences so i created a doodle with 2 possible dates and i would
encourage those who would be seriously interested to fill the doodle in.
they are both around august/september. if none of the dates fits you and you
really want to attend, you can suggest a possible other date in the comments
below the doodle table or writing me an email.
we want to make it as cheap as possible, so the idea is that the workshop
will be held at the ETH Zurich to save money for renting the space and the
food and drinks will be organized. at the moment we are searching for
sponsors so that there will hopefully be a contribution to the accommodation
costs. motivated students with limited funds can contact me with a letter of
motivation to see if we can find a solution for you to attend the workshop
as well. the flights cannot be paid, unfortunately.
the doodle is here:

cheers
lucie
PS: feel free to distribute this email to all potentially interested people-
thanks!

Dear Users of MSA-Talk:
MSA-Talk was set up to share information and discuss topics in the areas of mineralogy, crystallography, petrology, and geochemistry as a service of the Mineralogical Society of America. It is normally unmoderated, relying on users to stick to our science. However, we live in interesting times (?!), so there is motivation to share beyond geoscience. There are other list-serves that are specially established for political or social issues with participants looking for that information and those discussions. Please restrict your usage of MSA-talk to its designed function.
Thank you for your understanding.

Subject: [MSA-talk] Goldschmidt 2017 Session 05e: Lithosphere Evolution
during Subduction and Collision
Message-ID:
Dear Colleagues,
We would like to bring to your attention the following session, to be held at Goldschmidt 2017 in Paris (?session 05e)? on August 13-18 https://goldschmidt.info/2017/index
Lithosphere Evolution during Subduction and Collision
Convenors Sue O'Reilly, Georges Ceuleneer, Jingsui Yang and Yildirim Dilek
Keynote speaker: Cin-Ty LEE
The compositions and fabrics of crustal and mantle rocks record the history of large-scale tectonic and magmatic events that have shaped Earth's evolution. We aim to bring together perspectives from mineralogy, petrology, geochemistry, microstructure analysis, geophysics, and numerical modelling to:
* constrain the mantle source and generation of oceanic lithosphere
* track changes in mantle processes, composition, and heterogeneities through time
* probe the nature of subduction, ancient to recent
* examine the role of subduction and collision in lithospheric evolution and in shaping Earth's crust
* reveal the structure and geophysical properties of domains in collision zones
* understand the range of implications from these topics, including those on the global Carbon cycle, mantle convection models, timescales of recycling processes, and the role and nature of fluid phases and melt-rock interactions throughout the mantle.
Observations from exposed ophiolites and mantle terranes, from mantle xenoliths, and samples from active settings (e.g., from IODP drilling), provide many constraints. Recent analysis of ophiolites supports multiple episodes of melt extraction and migration in their genesis, and two-way deep recycling of crustal and mantle material during the formation of oceanic lithosphere. Studies of exposed mantle terranes probe ancient and modern subduction zones, shedding light on mantle fluid pathways, mineralisation processes, mantle modification due to magmatism, scale and distribution of mantle heterogeneities, and deep deformation styles. We encourage the synergistic use of the such observations with geophysical and geodynamical data, including contrasts in seismic velocity, attenuation, and anisotropy, magnetotelluric responses to water and melts, and dynamic modelling.
We aim to create a workshop environment in this Session which addresses a wide spectrum of subduction and collision processes and observations. It is very relevant to two current IGCP Projects (IGCP-649: Diamonds and Recycled Mantle and IGCP-648: Supercontinent Cycles & Global Geodynamics). We encourage participants to submit abstracts to this session.
Abstract submissions are now open and will close on April 1st.

Message-ID:
Dear colleagues,
Apologies for the cross-postings, but I hope 2017 is off to a good start for everyone. Paper submission for the Microscopy and Microanalysis 2017 Annual Meeting (St. Louis, MO, 6-10 August, 2017) is now open, and will close on 15 February. My co-conveners and I would like to draw your attention to:
Symposium A09, Standards, Reference Materials, and Their Applications in Quantitative Microanalysis.
We are looking for submissions dealing with the synthesis, evaluation, and need for new reference materials; evaluation, distribution, and maintenance of existing reference materials; the use of standards in quantitative microanalysis; and the application of quantitative microanalytical techniques to solving analytical problems. A full description of this session is included below. Papers may be submitted via the M&M2017 website: http://www.microscopy.org/mandm/2017/
We are also pleased to announce the invited speakers for this symposium:
John Hanchar, Department of Earth Sciences, Memorial University, Newfoundland

The organizers of Symposium A09:
Julien Allaz, University of Colorado ? Boulder
Anette von der Handt, University of Minnesota ? Twin Cities
Owen Neill, Washington State University
Symposium Description:
Standards and reference materials are essential for obtaining accurate quantitative compositional data from X-ray microanalysis by EPMA or SEM (WDS/EDS), as well as from other microanalytical techniques (LA-ICP-MS, SIMS, ?-XRF, FTIR, Raman spectroscopy, etc.). These materials must be rigorously evaluated for their reference compositions and homogeneity, must be widely available to the analytical community, and must be properly maintained to avoid contamination or deterioration. We welcome contributions on the synthesis, evaluation, distribution, and maintenance of standards and reference materials, as well as their appropriate use in microanalysis. We further encourage submissions on standard-based applications of quantitative microanalysis, or on the development of new quantitative microanalytical protocols.
Topics of interest include:
? The use of standards and reference materials in quantitative microanalysis, and the needs of the analytical community for improving such materials.
? Synthesis, evaluation, distribution, and maintenance of standards and reference materials.
? Development of new protocols for microanalytical techniques.
? Applications of standard-based techniques to solving microanalytical problems.

*Title:* Volcanoes: From Mantle to Surface
*Guest editors:* Keith Putirka and Kari Cooper
*ABOUT THIS ISSUE*
Volcanoes are the powerhouses of nature that can, within minutes, transform
a beautiful mountainscape into a desolate landscape devoid of life. Whether
eruptions are mild or catastrophic, volcanoes fascinate and captivate us.
But what controls whether a given magma will erupt or stall, and how do
processes in one part of the system affect others? Volcano science is
advancing rapidly, and improvements in monitoring tools, petrologic tools,
and modeling of volcanic processes have greatly improved our understanding
of volcanic behavior. This issue brings together contributions exploring
volcanic behavior throughout the crustal system.

My apologies for multiple postings. I want to draw your attention to the upcoming SCCM 2017 Abstract deadline: Feb. 24th. In particular, please consider submitting abstracts to the HEDS/WDM session:
These sessions focus on experimental, theoretical and computational descriptions of extreme material states that lie between condensed matter and high temperature plasma, which are found in the interior of large gas and ice giant planets, as well as on the pathway to inertial confinement fusion (ICF). Presentations describing novel approaches addressing the limits of scientific understanding of the phenomena by which atoms, ions and electrons interact and organize over a range of extreme conditions are particularly sought.

stress
Message-ID: <6B740313-8DCC-498D-9BCB-D7BEA5841BF8@univ-montp2.fr>
Dear colleagues,
You are doing geochemistry, and deformation of rock and minerals ? and you like PARIS !!!!!
then, this session is for you !
07D: GEOMATERIALS UNDER STRESS
Convenors: Sylvie Demouchy, Lars N. Hansen
Minerals and rocks undergo deformation under extreme conditions in Earth?s crust, mantle, and core. This deformation is continuous but also potentially non-linear, causing geodynamic processes to depend strongly on the underlying deformation mechanisms. Differential stresses can range from high, reaching fracture, to very low, remaining in the elastic field. This session focuses on the wide variety of deformation processes that geomaterials may endure: elasticity, visco-plasticity, friction, and brittle behaviour. These processes can additionally be linked to exotic crystal defects and inclusions, including the interplay between deformation and major- or trace element composition. This session aims to bring together an interdisciplinary group of geoscientists to discuss new results into rheological behaviour and their possible impacts in geodynamic settings from the inner core to the lithosphere. European Mineralogical Union (EMU), among its other activities, supports the participation of young scientists at major scientific meetings.
At Goldschmidt2017, EMU are offering travel support of 400 Euros to an awardee who must be first author of an abstract submitted to session 07d, and who is not older than 30 years. Potential candidates should apply by a simple email to the Sylvie Demouchy, who will select the awardee on the basis of significance and quality of the abstract. Click here for more information.
yours sincerely

Subject: [MSA-talk] possible health impact of growing food in and on a
remediated mine site
Message-ID:
The MSA office received a request about the possible health impact of growing food in and on a remediated mine site.
A coffee grower has been approached to reforest a mined-out area (Nickel Mine) with coffee trees. The mining company will rehabilitate the area by refilling the dug-out areas and adding one meter thick of top soils. The coffee company will plant 1,000 coffee trees per hectares on top of the rehabilitated area to produce coffee.
The question: will there be uptake of anything harmful by the coffee plants, particularly coming to rest in the coffee fruits (cherries) and their seeds. They are looking for any studies done that explain risks to human health associated with coffee tree (and their fruits) or any other fruit crop planted on top of such rehabilitated mined areas.

To my knowledge, Ni deposits also feature significant concentrations of Cd,
which is both mobile and toxic. I would advice both elements to be kept in
mind.
I have just carried out a quick research. Two interesting manuscripts from
Tezotto et al. (Field Crops Research, 2012) and Mazzafera (Plant Soil,

Hope this helps as starting point.

To my knowledge, Ni deposits also feature significant concentrations of Cd, which is both mobile and toxic. I would advice both elements to be kept in mind.
I have just carried out a quick research. Two interesting manuscripts from Tezotto et al. (Field Crops Research, 2012) and Mazzafera (Plant Soil, 1998) came up.
Hope this helps as starting point.

Message-ID: <1f57a7bba5ab40568430babc520171c3@ExMB1.ad.unb.ca>
Dear Colleagues
Abstract submission for Goldschmidt 2017 (13-18 August 2017) in Paris is now open at https://goldschmidt.info/2017/abstracts until April 1st.
Please consider sharing your research on unconventional chronometers with us in Paris and submit an abstract to the following session:
21E: BEYOND ZIRCON: ANALYTICAL DEVELOPMENTS AND NEW APPLICATIONS FOR UNCONVENTIONAL CHRONOMETERS IN EARTH AND PLANETARY SCIENCES
Convenors: Chris McFarlane, Kate Souders, David Chew, Paul J. Sylvester
Keynote: Thomas Zack (Gothenburg)
Geochronology using rock-forming minerals and biogenic materials (e.g., oxides, carbonates, silicates, halides) represents a new frontier in Earth sciences, driven by increasingly sensitive micro-analytical instrumentation (e.g., LA-(MC)-ICP-MS and SIMS) and novel sample preparation techniques and analytical strategies for bulk samples (TIMS). Age information determined by these techniques can be used to determine the chronology of igneous, metamorphic and tectonic events as well as sedimentary provenance and potential ages of sedimentation. In contrast to traditional accessory mineral geochronology (e.g. U-Pb zircon geochronology), the textural and petrogenetic context (e.g, P-T-X conditions) of rock-forming minerals and biogenic materials is typically obvious and grain sizes permit analysis of large sample volumes to compensate for lower absolute parent isotope concentrations. Major hurdles include development and testing of reference materials and quantification of parent isotope concentrations typical of rock forming minerals in different geological settings and bulk compositions. This session solicits papers describing new method developments and case studies using a variety of radiogenic isotopes systems (e.g. U-Pb, Lu-Hf, Sm-Nd, Rb-Sr) applied to earth and planetary materials. Contributions describing new hardware and reference materials applicable to major-mineral geochronology are also welcome.
Best regards and hope to see you in Paris!

As they plan to add 1 meter of topsoil (presumably free of Cd, Ni, etc.),
and coffee tree roots extend mostly within the top 45cm of soil, maximum
60cm, the composition of the subsoil might be irrelevant? (unless Cd, etc,
can migrate upwards into the new topsoil? - which 9if it occurs at all)
could probably be prevented by adding something to render the heavy metals
insoluble.)

Properties of Earth Materials: Past Achievements and Future Objectives
Message-ID: <0B3534ED-68F5-4B05-9421-D85F9F664845@sbg.ac.at>
Dear Colleagues:
We would like to bring to your attention the following session that will be held at the Goldschmidt 2017 conference in Paris.
https://goldschmidt.info/2017/program/programViewThemes
07b: Thermodynamic Properties of Earth Materials: Past Achievements and Future Objectives
Convenors: Charles A. Geiger (Salzburg) and Pascal Richet (Paris)
Geologic processes, whether or not in chemical equilibrium, are governed by thermodynamics because reaction kinetics are also driven by differences in the relevant thermodynamic potentials. Thus, precise knowledge of thermodynamic properties of all types of Earth materials (i.e., minerals, melts, glasses, fluids, liquids and gases) is mandatory. In terms of minerals, a number of thermodynamic databases, including internally inconsistent ones, have been constructed from experimental results acquired over many years. They list Cp?, S?, H?, V? and G? for many phases and for different temperature and pressure conditions. How good are these compilations and what phases need further study? What kind of experimental measurements, computations and theoretical analysis are required to better understand the thermodynamic stability and properties of all Earth materials? What new avenues or types of research are being envisioned and developed in the fields of mineralogy, petrology, and geochemistry? This session will consider a wide range of contributions that are directed towards investigating, analyzing and understanding the thermodynamic behavior and properties of minerals, melts, glasses, fluids, liquids and gases. An emphasis will be placed on those studies that make a critical analysis of the state of the field or propose new directions of study.
Abstract submissions are now open and the deadline for submission is April 1st.

We invite diverse abstract submissions to the following session at
Goldschmidt 2017:
Diffusion and Transport Processes in Geomaterials (Session 07e)
This session covers recent studies of transport phenomena in Earth
materials, and their role in the geochemical and physical evolution of
the Earth system. Atomic and molecular diffusion affect the major and
trace chemical composition and evolution of earth materials from grain
to reservoir scales, influencing our understanding of mineral and rock
evolution; thermal and barometric history; zoning at multiple length
scales; and rates of reaction, metamorphism, and partitioning. Heat
diffusion controls the dynamical and thermal state of Earth?s interior
from the crust to the core, playing a central role in magnetic field
production. Fluid viscosity and rheology of solid and mixed-phase
systems similarly govern the dynamics of the interior, including
mixing of reservoirs, aqueous fluid and magma transport, and formation
of deep structures. Electrical transport enables essential tracing of
the conditions and dynamics of Earth's subsurface. We invite field,
laboratory, and theoretical investigations discussing the character
and role of such varied transport phenomena, from their origin in
fundamental physical principles to their influence across a range of
time and length scales.
Planned Keynote: Glenn Gaetani (Woods Hole Oceanographic Institution)

Message-ID:
Dear colleagues,
We welcome you to submit an abstract to our session on recent observational
and/or experimental advances in thermochronology at Goldschmidt 2017 in
Paris, France, August 13-18. The abstract submission deadline is April 1.
*Session 21f: Innovations and Advances in Thermochronology*
Thermochronology techniques developed over the past 30 years have been
invaluable tools in quantifying the timing, rates and patterns of tectonic,
erosive, and extraterrestrial processes. Nonetheless, fundamental questions
concerning the mechanistic underpinnings of these techniques, such as
uncertainties in diffusion kinetics and the effects of radiation damage,
still remain. This session invites abstracts on recent experimental and
observational studies that improve our understanding of new or existing
thermochronology systems. We welcome contributions from both the high and
low temperature thermochronology communities.

Message-ID: <1973fe02-072e-03ce-84b0-3d93a032ca0b@impmc.upmc.fr>
Dear colleagues,
We invite you to submit an abstract to our session concerning fluids and
melts inside planets, which will be part of the upcoming 2017
Goldschmidt conference in Paris, France on August 13-18.
Session Details:
Title: (04F) Fluids and Melts Inside Planets: Observations, Models and
Experiments
Keynote: Paul Asimow (California Institute of Technology)
Invited Presenters: Razvan Caracas (Universit? de Lyon) and Laura Cobden
(Utrecht University)
Fluids and melts play an important dynamic role in the physical,
thermal, and chemical evolution of planetary interiors. The presence of
liquids in planetary interiors has a significant impact on a range of
fundamental geological processes and physical properties (i.e. rheology,
electrical conductivity, diffusivity, density, partitioning, among
others). Because of this broad range of effects, studying geological
fluids/melts is foundational to understanding the formation,
differentiation, and evolution of Earth and other planetary bodies.
However, the study of liquids at extreme pressures and temperatures
presents unique challenges. And so, this session aims to unite
researchers from geochemical, experimental, theoretical/computational,
and seismic/geodynamical backgrounds who investigate the physical and
chemical properties of melts. Relevant topics include but are not
limited to: partial melting and melt extraction, liquid-solid
partitioning, the role of fluxes on melting, experimental studies of
melts at high pressures, the seismic detection of mantle melt
distribution, geodynamic studies of melting in planetary bodies, and the
study of melting at conditions relevant to exoplanetary interiors.
Conveners: Elizabeth Thompson and Alisha Clark
The abstract submission deadline is April 1st.

Subject: [MSA-talk] epoxy for grain mounts
Message-ID:
All,
We have some old permanent grain mounts (in epoxy or Canada balsam) that we've used for optical mineralogy instruction for decades. They are getting quite yellowed and cracked, so I'd like to make some newer mounts.
Like an idiot, I decided to experiment with a clear-drying epoxy purchased from the hardware store, but found out that it was loaded with mysterious tiny cubic crystals (not sure what exactly) and that it dries in swirly patterns...so its not exactly clear. That obviously didn't work. So what type/brand of thin-section epoxy would you all recommend for this?
Also, I would like to label each grain mount with white paint that I can write overtop with ink. What do you recommend as far making permanent labels like this that won't smudge over time? (I'd also like to use this on rock samples).
I haven't made thin-sections in quite a while, so need a refresher.
Thanks.
- Kent

I want to draw your attention to the upcoming SCCM 2017 Abstract deadline: Feb. 24th. In particular, please consider submitting abstracts for the HEDS/WDM session:
These sessions focus on experimental, theoretical and computational descriptions of extreme material states that lie between condensed matter and high temperature plasma, which are found in the interior of large gas and ice giant planets, as well as on the pathway to inertial confinement fusion (ICF). Presentations describing novel approaches addressing the limits of scientific understanding of the phenomena by which atoms, ions and electrons interact and organize over a range of extreme conditions are particularly sought.
Further information on the conference location and additional deadlines can be found at:

Subject: [MSA-talk] possible health impact of growing food in and on a remediated mine site
The MSA office received a request about the possible health impact of growing food in and on a remediated mine site.
A coffee grower has been approached to reforest a mined-out area (Nickel Mine) with coffee trees. The mining company will rehabilitate the area by refilling the dug-out areas and adding one meter thick of top soils. The coffee company will plant 1,000 coffee trees per hectares on top of the rehabilitated area to produce coffee.
The question: will there be uptake of anything harmful by the coffee plants, particularly coming to rest in the coffee fruits (cherries) and their seeds. They are looking for any studies done that explain risks to human health associated with coffee tree (and their fruits) or any other fruit crop planted on top of such rehabilitated mined areas.

Subject: [MSA-talk] epoxy for grain mounts
Message-ID:
Dear Kent,
When I worked under Bob Martin as an undergrad, he recommended using appliance touch-up paint for the base of such labels, using an india ink drafting pen with a very fine tip (0.1 mm) for the lettering.
I used this on both glass slides and rock samples, and I never had trouble with smudging or wear. It's possible for the paint to chip if the samples are handled roughly, of course, but this would present a problem for any label. Also, I have heard of some people putting a thin layer of clear epoxy over the label, as added assurance, but like I said, mine were (and, 20 years later, continue to be) fine without it.
Finally, I have used Petropoxy 154 from Burnham Petrographics with great success to make grain mounts on glass slides. I did not use frosted slides, and the bond to the glass was very strong. I would mention that this epoxy spreads slightly as it cures on a hotplate, so be sure to account for that when placing samples near the edge of the glass or if placing different samples next to each other.
Hope this helps.
Best,
Peter

Ralf and others:
The provenance of conflict mineral is a difficult problem. Catherine McManus (at Materialytics) and I have been working on the provenance of coltan, wolframite, cassiterite, gold, and diamond, using Laser Induced Breakdown Spectroscopy (LIBS). This technique differs from more traditional geochemical analysis because information about the entire periodic table is recorded in every spectrum and because analysis is rapid, allowing a very large number of samples to be analyzed. We are able to determine the country of origin for these minerals at greater than 91% accuracy. Here are links to papers presented at GACMAC 2016 and GSA 2015:
http://gac.esd.mun.ca/gac_2016/search_abs/sub_program.asp?sess=98&form=10&abs_no=217
https://gsa.confex.com/gsa/2015AM/webprogram/Paper261650.html
The biggest issue with applying this technique to the sociopolitical problem of conflict minerals is that a large number of samples from many locations are required. Catherine and I are continuing research in this area and welcome samples from anyone. If you are interested in a collaboration, please contact me at nmcmilla at nmsu.edu or Catherine at c.mcmanus at materialytics.com.

06m - MELTING DURING (U)HT, (U)HP CRUSTAL METAMORPHISM
Partial melting of crustal rocks is a common geological phenomenon in our tectonically active planet. HT metamorphism and crustal melting, accompanied by melt extraction and magma migration to upper levels, constitute a fundamental process for the chemical differentiation of Earth?s crust and formation of granitoid plutons. The extensive melting and melt loss predicted to occur during HT-UHT metamorphism have direct impact on the rheology of the orogenic infrastructures and redistribution of high heat-producing elements. On the other hand, partial melting of deeply subducted crust is a key process for mass transfer and element recycling through subduction zones. Because partial melting allows rocks to weaken rapidly and effectively, it has also been proposed as an active mechanism in the exhumation of UHP crustal slices at mantle depths. While more and more publications directly or indirectly evidence the presence of melts at these extreme metamorphic conditions, we invite contributions using a variety of approaches to investigate melting of crustal rocks during (U)HT, (U)HP metamorphism, including, but not limited to, geochemistry, metamorphic and structural analysis, geochronology, field observations, phase equilibria calculations and numerical modeling. In particular, we encourage contributions that apply novel and innovative approaches or integrate diverse datasets with crustal scale models.

Knet,
I used to use the paint that comes in little bottles for painting model
airplanes - it is slower to dry than white-out but does not flake over
time. Comes in different colors- can use diffeent colors for different
collectios. Then label with rapidograph and when dry, seal with clear nail
polish. These hold up well over time.

Subject: [MSA-talk] Goldschmidt session 11b: Metal Isotope Redox Indicators
Message-ID:
Colleagues,
Please consider submitting an abstract to our session on metal isotope
redox indicators. The meeting is in Paris, France August 13th-18th.
Abstract deadline is April 1st.
*11b. Metal isotope redox indicators: Toward mechanistic understanding and
predictive power*
Twenty years of metal stable isotope geochemistry have revealed redox
transformation-driven isotope fractionations for elements such as Fe, Mo,
U, Cr, Hg, Cu, and Se (a redox-active metalloid). The observed isotopic
variations in geologic and environmental samples have been used to infer,
for example, past redox states of the oceans, the presence of microbially
mediated metal reduction, and the relative roles of sorption and reduction
in governing environmental mobility of metals. Despite considerable
progress, improved mechanistic understanding of fractionation,
quantification of fractionation factors from both laboratory and field
settings, and efforts to reconcile lab and field observations are needed to
interpret data from natural samples with confidence and accuracy. For
example, this enables predictive reactive transport modeling of
concentration and isotope patterns in fluids, low-temperature ore deposits
(e.g., roll-fronts, supergene Cu deposit), sediments, and soils. We seek
contributions highlighting experimental, theoretical, or field-based
inquiries into mechanisms of redox-driven metal isotope effects with
applications ranging from molecular-scale investigations to field-scale
reactive transport.

Subject: [MSA-talk] Goldschmidt session 4d
Message-ID:
Dear colleagues,
I would like to bring your attention to the following session at Goldschmidt 2017 in Paris:
Session 4d: Thermodynamics and Diffusion Kinetics within the Core and
Mantle: A Session in Honor of Jibamitra Ganguly and Surendra Saxena
Convenors: Elias Bloch, Yingwei Fei
Keynote: Bernard Wood
Invited Speakers: Guoyin Shen, Dan Frost
Summary:
Processes occurring deep within the Earth have fascinated both Jibamitra
Ganguly and Surendra Saxena since beginning their careers as petrologists
nearly half a century ago. Although experimental work has been a benchmark
of Jibamitra and Surendra's work, they have always recognized the
importance of integrating experimental studies with data from geological
materials, as well as with geophysical and geodynamic models and
observations. This session is intended to highlight recent advances in our
understanding of processes occurring in the mantle and core, primarily
through the lens of thermodynamics and diffusion kinetics; however, both
Jibamitra and Surendra have made contributions to a wide range of topics
in Earth and Planetary Science, and we welcome submissions focused on
meteorites and the Earth's crust, as well as advances in multicomponent
diffusion, geothermobarometry and thermochronology. We particularly
encourage studies that utilize a combination of experimental or kinetic
data with geochemical data from natural samples or geophysical
observations.
All the best,

Subject: [MSA-talk] Goldschmidt Session 06G: Fluid,
Mineral and Melt Inclusions as Petrologic Indicators to Unravel
Geologic Processes
Message-ID:
Dear Colleagues,
Abstract submissions for Goldschmidt 2017 in Paris, France, are now open at
https://goldschmidt.info/2017/abstracts. The abstract deadline is April 1st.
If your work utilizes inclusions of any sort (fluid, melt or mineral), then
please consider submitting an abstract to our session:
*06G: Fluid, Mineral and Melt Inclusions as Petrologic Indicators to
Unravel Geologic Processes*
Conveners: Kyle Ashley, Claudia Cannatelli, Daniel Moncada, Matthew
Steele-MacInnis
The keynote speaker will be John MacLennan (University of Cambridge) and
the session description is as follows:
*The growths of crystals in rocks often lead to imperfections in the
crystal in the form of fluid, melt, or mineral inclusions. Geological
fluids rising from the mantle to the crust acquire, transport, degas and
deposit different elements in igneous, metamorphic and sedimentary rocks.
Numerous studies over the past half-century have described fluid and melt
inclusions as the best repositories to investigate changes in inclusion
properties and track the evolution of these fluids through time. Recently
there has been a growing application of mineral inclusions in rigid hosts
to constrain pressures and temperatures of porphyroblast growth. This
session aims to bring together researchers that focus their studies on the
application of fluid, mineral and melt inclusions to understand the nature
and timescale of geological processes in different geodynamic environments.
Multidisciplinary approaches that combine natural observations, structural
and/or deformation paths, laboratory experiments and theoretical and
thermodynamic models are particularly encouraged.*
We look forward to seeing you in Paris!
Best wishes,

Subject: [MSA-talk] Tectonochemistry Session at Goldschmidt 2017 (06f)
Message-ID:
Dear Colleagues,
We would like to bring your attention to the session Tectonochemistry (06f) at the GOLDSHMIDT 2017 conference in Paris, France (August 13 ? 18).
Organizers: Tanya Ewing (University of Lausanne), Andrew Smye (Penn State University), Christopher Spencer (Curtin University)
Keynote talk: Frances Cooper (University of Bristol)
Invited lecture: Forrest Horton (Caltech)
Tectonochemistry is a branch of geochemistry aimed at understanding tectonic processes. The potential breadth of tectonochemistry is wide and includes (but is not limited to) geochemical studies of subduction-, collision-, rift-, and plume-related processes that contribute to a greater understanding the evolution of Plate Tectonics on Earth. We invite submissions from tectonochemists integrating a variety of geochemical methods and principles in spatial and/or temporal contexts in order to resolve large-scale tectonic questions. We anticipate particular interest from those studying evolution of orogenic and thermo-magmatic systems, timescales of crustal processes, generation and differentiation of the crust. This session will highlight the breadth of activities happening across this fundamental branch of geochemistry.
Further information for session 06f are available at:
https://goldschmidt.info/2017/program/programViewThemes#session_261_2321
Abstract submissions are now open on the GOLDSHMIDT 2017 website https://goldschmidt.info/2017/abstracts and will close on 1st April 2017.
We hope to see you at this session in Paris and look forward to receiving your abstracts.

Subject: [MSA-talk] Goldschmidt 5h: Transport of Volatiles,
Halogens and Redox Sensitive Elements between the Crust and the
Mantle
Message-ID:
Dear colleagues,
we would like to draw your attention to our session # 5h at this year's Goldschmidt Conference (August 13-18, Paris, France):
"Transport of Volatiles, Halogens and Redox Sensitive Elements between the Crust and the Mantle:
The cycling of volatiles and redox sensitive elements (e.g. halogens, C, S) is mediated by devolatilization and redox reactions between Earth?s major reservoirs. These exert a fundamental control on element mobility and chemical fluxes, as separation and migration of fluids allow a comparably rapid transfer of chemical signatures from one reservoir to another. This session aims to attract geochemists and petrologists studying redox reactions and mass transfer of elements and isotopes in subduction zones and the exchange of these elements between the mantle and the crust. We welcome contributions that employ natural samples, experimental petrology, geochemistry, thermodynamic modeling, and new high-precision analytical methods to study the dynamics and effects of volatile transport, including but not limited to metal mobilization, ore precipitation, redox effects, mineral?melt?fluid interaction and boundary effects; as well as degassing, fluid-pathways and fluid-transport dynamics, volcanic degassing, and mobility, diffusion and partitioning in mantle sources."
Keynote: Mark Kendrick (Australian National University)
Invited talks: Fleurice Parat (Universite Montpellier 2) and Margarita Merkulova (ESRF, Grenoble)
Abstract submission deadline is April 1st, 2017!

Subject: [MSA-talk] Mineralogical question
Message-ID:
Dear all,
While studying a specimen I collected last week, and looking at the
minerals present, I noticed the following:
A. layer of smithsonite on matrix, with small rhombohedral crystal faces at
the top
B. in places, A covered by unknown yellow/green crust and/or balls
C. in places, A with B on top covered by colorless calcite
Since A and C are both carbonates, and B grew in between, I guess it is not
a stupid idea to assume B might be a carbonate as well, or is it?
Besides a carbonate, what else could B likely or eventually be?
FYI: the smithsonite crystals are in great shape, don't look etched at all.

Pictures would help. The unknown phase does not have to be a carbonate, because multiple "waves" of crystallization could occur. Also, where is the specimen from?
Hope this helps,

Hi Herwig,
There is certainly no reason why the B mineral couldn?t be from any of a number of mineral classes. Of course, mineral A (smithsonite) must be stable in contact with the solution that formed mineral B, and mineral B (and mineral A) must be stable in contact with the solution that formed mineral C (calcite).
To ask an obvious question, have you tested whether mineral B effervesces in acid (bearing in mind that some carbonates react more slowly than others)?

Actually, thinking it over, there are a few conclusions to be drawn, I think, from this simple HCl test:
1. "B" is not a carbonate
2. "B" does not contain Pb (otherwise the balls would turn white instead of colorless)
Any other conclusions possible?

Hi Tony,
Thanks for asking the obvious question, Why in the world did not I think of that myself?
I just took a small sample and pushed it in a drop of HCl.
No gas bubbles. BUT, to my surprise, at first glance it looked like the greenish yellow balls and crust became smaller.
Then I looked more closely, and noticed I could still see their outline (due to impurities on their surfaces), and while the colorful interior became smaller and smaller, the colorless mass surrounding it became larger and larger. In short, it really looks now like the yellow balls have been replaced by a colorless gel.
No idea if that is by any means conclusive for something ...

Subject: Re: [MSA-talk] Mineralogical question
Regarding my last question: I was actually wondering about general answers, rather than specific answers.
So in other words: Besides a carbonate, what other mineral groups (arsenates, phosphates, ...) might fit such a sequence of crystallization?
And what groups are the most likely ones for "B"?
Cheers, Herwig

Dear all,
While studying a specimen I collected last week, and looking at the minerals present, I noticed the following:
A. layer of smithsonite on matrix, with small rhombohedral crystal faces at the top
B. in places, A covered by unknown yellow/green crust and/or balls
C. in places, A with B on top covered by colorless calcite
Since A and C are both carbonates, and B grew in between, I guess it is not a stupid idea to assume B might be a carbonate as well, or is it?
Besides a carbonate, what else could B likely or eventually be?
FYI: the smithsonite crystals are in great shape, don't look etched at all.
Cheers, Herwig

Hi Tony,
Thanks for asking the obvious question, Why in the world did not I think of
that myself?
I just took a small sample and pushed it in a drop of HCl.
No gas bubbles. BUT, to my surprise, at first glance it looked like the
greenish yellow balls and crust became smaller.
Then I looked more closely, and noticed I could still see their outline
(due to impurities on their surfaces), and while the colorful interior
became smaller and smaller, the colorless mass surrounding it became larger
and larger. In short, it really looks now like the yellow balls have been
replaced by a colorless gel.
No idea if that is by any means conclusive for something ...
Cheers, Herwig

Actually, thinking it over, there are a few conclusions to be drawn, I
think, from this simple HCl test:
1. "B" is not a carbonate
2. "B" does not contain Pb (otherwise the balls would turn white instead of
colorless)
Any other conclusions possible?

Perhaps "B" is organic, a layer of dehydrated algae cells that grew in a

Not a conclusion, but yet another possibility. If you place a bone
splinter (hydroxy-apatite) into a drop of diluted HCl under the microscope
you receive that same observation. So the yellow/green balls might be a
phosphate mineral as well.

Dear colleagues,
We invite you to submit an abstract and participate in the session on
cesium and radiocesium in (but not limited to) rocks and soils, which
will be part of the upcoming 2017 Goldschmidt conference in Paris,
France on August 13-18.
The abstract submission deadline is April 1st. To submit your abstract,
please visit: http://goldschmidt.info/2017/abstracts
Session: 13i. Accumulation, Mobility and Availability of Cesium and
Radiocesium in Rocks, Soils and Other Environments
Session Keynote Speaker: George Shaw (University of Nottingham)
Synopsis: Studies of (stable) cesium and radiocesium lead to improved
knowledge regarding their accumulation, mobility and availability in
rocks, soils and other environments. This knowledge is useful for
predicting the fate of radiocesium that has been accidentally released
in soil and water environments. The study of cesium in shales and other
clay-bearing rocks likewise is important, given the possibility that
they would become traps for radiocesium. In the framework of the
Chernobyl and Fukushima Da?chii disasters, knowledge emerged concerning
the behaviour of cesium and radiocesium in soils and waters. Key
questions remain regarding cesium and radiocesium residence times in
soil layers, and the quantification of available or bioavailable
fractions. Such factors are of primary important for modelling uptake
processes into vegetation, and for understanding the long term transfer
to deeper soil layers. This session is intended to gather geochemists
interested in cesium and radiocesium mobility and fixation both in
rocks, soils and other environments. Contributions on techniques that
distinguish the (bio)available fractions cesium and radiocesium in
soils, as well as those focused on soil/solution/root continuum modeling
based on field or laboratory observations, are also welcome.
We are looking forward to seeing you in Paris!

Dear Colleagues
Abstract submission for the Goldschmidt Conference 2017 in Paris is now open at https://goldschmidt.info/2017/abstracts and will close on April 1st. The meeting is 13-18 August 2017.
You may consider submitting an abstract to the following session:
07I: ADVANCES IN VIBRATIONAL SPECTROSCOPY AS A TOOL FOR IDENTIFING PHYSICAL CHEMICAL AND DYNAMIC PROPERTIES OF GEOMATERIALS
Convenors: Monika Koch-Mueller , Sergio Speziale
Vibrational spectroscopies are essential tools to investigate chemical and physical properties of Earth materials. Raman and infrared spectroscopy provide information regarding thermodynamic properties, the incorporation of volatiles order-disorder of geomaterials, site occupancies, local structural environments and many other structure-related properties. Brillouin spectroscopy allows one to determine the full elastic tensor and quantify high-frequency relaxation processes. The different vibrational spectroscopic methods supply fundamental input parameters for thermodynamic modeling and for geodynamics and geophysical large scale simulations. The continual advancement of high-pressure techniques makes vibrational spectroscopies the method of choice for in-situ studies probing the changes of the above mentioned properties to changes in pressure and temperature. In addition one can gain information on structural and electronic transitions of minerals at pressures and/or temperatures. Their combination with a wide range of other experimental and computational techniques offers new opportunities to understand microscopic processes in the Earth?s deep interior. In this session we invite contributions from experimentalists and theorists based on optical and IR spectroscopy, Raman and Brillouin scattering and other vibrational spectroscopy methods to probe the microscopic structure and dynamic of Earth?s solid and fluid constituents in order to understand the chemical and physical behavior of the Earth from the crust to deep interior.
keynote speaker: Bruno Reynard, ENS, Lyon, France

Message-ID: <90276963.2465870.1487618646821.JavaMail.zimbra@psu.edu>
Dear all,
I am forwarding this announcement on behalf of Svetlana Entcheva:
Dear colleagues!
I am sending you the first announcement of the Ninth International Symposium "Mineral diversity - Research and Preservation" and brief information about it. We would be honored if you take part in its work.
Sincerely yours,
Svetlana Entcheva - Secretary of Symposium
mindiv1 at abv.bg
As part of the SOFIA INITIATIVE ?PRESERVATION OF MINERAL DIVERSITY?, the Ninth International Symposium on "MINERAL DIVERSITY - RESEARCH AND PRESERVATION? will be held 16- 18 October 2017 in SOFIA, BULGARIA.
More information and registration information at < http://www.earthandman.org/wp-content/uploads/2017/02/Circular_IX-Symposium-_EN.pdf >
-----
The idea for sustainable development in its many aspects has always been among the main driving forces and motivations for the activities at the Earth and Man National Museum, Sofia. Mineral diversity is of decisive significance for the sustainable development of the biosphere, being the substrate for the existence of various forms of living matter. Minerals, ores and rocks lay also in the foundation of modern technological civilization. The preservation of natural mineral diversity is a fundamental problem, equal in significance to the preservation of biological diversity.
It is important to take into account that the role of mineralogical museums is of immense importance. They preserve samples of the condemned to destruction non-living nature sufficient to satisfy in both quantity and quality the scientific and esthetic needs of future human generations.
The initiative for preservation of mineral diversity was begun at our museum in 1999. Later it was named The Sofia Initiative with an Internet seminar in 2000, as well as eight International symposiums in 2000, 2002, 2005, 2007 , 2009, 2011, 2013 , and 2015. The main themes of the previous symposia were:
?Mineral collections and their catalog publications ? fundament for descriptive, genetic and applied research?,
?Historic scientific and thematic mineral collection?,
Mineral Diversity preserved in-situ and ex-situ ? state of play?,
?Monographic mineral collections?,
?Scientific collections of famous mineralogists ? historic and contemporary interpretations?,
?Regional collections?, and
?Presentation of scientific mineral collections, preserved at universities, scientific institutes, museums, mine enterprises, in private collections of mineralogists ? professional and amateurs?.

Dear all,
Here's an update of this thread.
First, I thought lead minerals would always form a white rim of insoluble
PbCl2 when attacked by HCl.
Thanks to Tony Kampf, I now know the behavior of lead minerals in HCl is
way more diverse:
"I have described quite a few Pb-bearing minerals and I always test their
behavior in HCl. In two cases, ottoite and plumbophyllite, I observed the
formation of an insoluble residue of cotunnite. In a number of cases,
including several of the Otto Mountain minerals, I observed the initial
formation of a white decomposition product, but it then slowly dissolved.
There were also several Pb-bearing minerals that dissolved easily in HCl
without the formation of any residue, e.g. fuettererite and
ferribushmakinite."
I was glad Alfredo Petrov mentioned the possibility "B" was organic. At
first, when collecting this material on the old mine dump, I actually
thought these crusts to be some kind of lichen. Especially when I found
some lichens that almost looked identical. It was only when I found the
same crust covered with clear calcite crystals (when I broke open a boulder
that did not show any cracks or seems on the outside), that I was convinced
the crusts were not lichens.
Thanks too to Ralf Milke for his info on the bone splinter
(hydroxy-apatite); very interesting. Apparently more than one group of
minerals can form gels, when attacked by HCl. Peter Tice was so kind to
share the following info:
" I've worked with eudialyte group minerals quite extensively, and
the mineral (and group) name comes from the Greek *eudialytos*, meaning
easily dissolved, as it gelatinizes in HCl. So I wonder if you might also
have a secondary silicate involved in the mix."
*=> are there other minerals that are well known for such behavior?*
Finally, the most embarrassing part of the update:
Layer "A", previously thought by me to be smithsonite, turned out to be
(just) quartz..
What fooled me, were the 3 large dominant rhombohedral faces (that make up
the points of the quartz crystals) , together with the impression that the
specimen was quite heavy. Only after doing a HCl test on this layer and
then looking closer at the morphology, did I find a few micro crystals that
stood out and showed the 6-sided prism. In combination with a conchoidal
fracture and its relatively high hardness, it is now safe to assume layer A
to be quartz.
Since "B" is not suited to be studied in more detial with a polarising
microscope, I have sent samples out for EDS and Raman. Will keep you posted.
Thanks again to all who contributed to this thread!
Cheers, Herwig

Hi,
I'm not sure if anyone else has replied
to Ralf's suggestion below, but I wanted to
clarify his observation. The mineral in bone is
chemically quite distinct from stoichiometric
hydroxylapatite. Most importantly, bone apatite
contains about 6 wt% CO3 (mostly substituted for
phosphate). It is the carbonate component that
is fizzing when you put a chip of bone into acid.

Dear Colleagues,
The Mineralogical Society of America is seeking nominations for the 2018
Roebling Medal.
The Roebling Medal is the highest award of the Mineralogical Society of
America for scientific eminence as represented primarily by scientific
publication of outstanding original research in mineralogy. The science
of mineralogy is defined broadly for purposes of the Roebling Medal, and
a candidate need not qualify as a mineralogist; rather his published
research should be related to the mineralogical sciences and should make
some outstanding contribution to them. Service to mineralogy, teaching,
and administrative accomplishment are not to be considered primary merit
for the award. Nationality, personality, age of candidate, or place of
employment shall not be considered.
A full description of the award, a list of previous recipients, and
instructions for submitting nominations can be found at
http://www.minsocam.org/msa/awards/roebling.html
The deadline for submitting nominations for the 2018 Roebling Medal is
June 1, 2017.
Please do not hesitate to contact me if you have any questions.
Best regards,
Raj
(Chair of the MSA Roebling Medal Committee)

Subject: [MSA-talk] Question about fluid inclusions
Message-ID: <004001d28c66$277c5c20$76751460$@netzero.net>
Hello MSA members,
This is related to Friedemann Freund?s work on MgO. Freund has made observations, summarized below, and would like to discuss them with competent and experienced people working in the field of crystal growth, inclusions, and peroxy (such as O3Si-OO-SiO3) defects. If you have any advice, please reply to mercury_miner at netzero.net . Please do not reply all, as I do not wish to clog up member email boxes.
Observations: the IR spectrum of clouded arc-grown MgO (pic attached) shows that the presumed inclusions creating the clouding in fact contain molecular H2 on interstitial sites inside the MgO matrix, as well as aliphatic hydrocarbons. When one cleaves or crushes the MgO crystal, a gush of H2 rushes out, followed by a slow H2 outgassing that follows a strict square root of the time dependence, indicating that a diffusion of interstitial H2 to the freshly-created fracture surfaces.
Upon taking a closer at such MgO crystals (which Dr. Freund has done for years), one sees something that should interest the geoscience community. Even though the MgO crystals were grown under the viciously reducing conditions of a carbon arc [and in ultra-clean conditions], they are loaded with peroxy anions, each the equivalent of one interstitial O atom added to the MgO structure. At the same time, when one crushes meticulously-cleaned gem-quality olivine crystals from, say, San Carlos, AZ, one can extract very complex organic molecules with molecular weights up to 600 amu. See the attached pdf, ?Plausible polyatomic molecules?? Crushed melt-grown MgO single crystals extracted with solvent produce so much organics that one can crystallize, for example, mm-sized succinic acid, a four-carbon dicarboxylic acid, as shown in the last attached jpg. Obviously these are not coming out of fluid ?inclusions? and are a mystery to be considered.
Have any others seen organic oddities as inclusions that might be related to these observations? Are any others interested in peroxy defects? Again, please reply to mercury_miner at netzero.net and not to the MSA listserve.
Thank you for reading.
