Thank you. ? *Public Job Advertisement* * * Since October 2015, the DFG International Research Training Group ?Surface processes, Tectonics and Georecources in the Andean Foreland Basin of Argentina? (StRATEGy) is established at the University of Potsdam?and runs in cooperation with the GFZ German Research Centre for Geoscience and our Argentinian partner universities in Buenos Aires, Salta, Jujuy, C?rdoba, and Mendoza. ?StRATEGy? aims to conduct an interdisciplinary study of the source-to-sink system of the Argentinian Andes. Our study addresses the complex relationships between tectonics, climate, erosion, sediment deposition, and?the environmental conditions prone to the generation, migration, and accumulation of hydrocarbon resources and metallogenesis. The foreland and the transition to the Andean orogen interior is characterized by ongoing,?yet highly diachronous and spatially disparate tectonism, in addition to pronounced contrasts in relief, rainfall, and erosion. These characteristics make this region an outstanding natural laboratory to study surface processes?and their tectonic and climatic forcing factors that impact sediment production and mass-transfer on multiple spatiotemporal scales. *10 Academic Staff Member* *Req.

(see project abstract below). The selected postdoctoral scholar will be based at Queens College of the City University of New York (primary supervisors Marc-Antoine Longpr? at CUNY and Adrian Fiege at the American Museum of Natural History) for year 1 and at Southern Methodist University (primary supervisor Rita Economos) for year 2. The project will be conducted in close collaboration with C?line Vidal (University of Cambridge), IPGP (France) and CVGHM (Indonesia). The postdoc?s responsibilities will include XANES, FT-IR, EPMA, and SIMS data collection and interpretation, as well as preparation of manuscripts for peer-reviewed publication. A PhD in Earth Science or a related sub-discipline, with specialization in petrology/geochemistry, is required. Experience with melt inclusion analysis and microbeam analytical methods (e.g., EPMA, FT-IR, SIMS, LA-ICP-MS or XANES) is preferred. The start date is as soon as September 1st. We will begin considering applications on June 30th, but will accept applications until the position is filled. Applicants should send a motivation letter (1-2 pages) that includes applicable research experience, a CV with publication list, and contact information for at least two references as a single PDF document to Marc-Antoine Longpr? (mlongpre at qc.cuny.edu). Best regards, Rita Economos Marc-Antoine Longpr? Adrian Fiege C?line Vidal Project abstract: Sulfur is the third most abundant volatile element in volcanic systems following water and CO2. Release of sulfur to the atmosphere during volcanic eruptions can perturb climate on a global scale and cause acid rain, resulting in significant environmental impact. The eruption of Mt. Samalas on Lombok Island, Indonesia, in 1257 CE generated the largest volcanic sulfur emission event of the last 2000 years. This event is coincident with a multi-year global cooling event around the beginning of the ?Little Ice Age?. The central research question of this project is: how did this volcano build up so much eruptible sulfur? The scientist participants will test hypotheses of sulfur enrichment mechanisms by probing deep into sulfur?s properties and behavior within sulfides, apatites, and volcanic glasses (rapidly cooled melts) from pumice samples from this eruption. The project will utilize the most advanced analytical techniques to investigate sulfur chemistry, many of which were developed recently by participants on the research team. This project will yield new insights into the capability of magmatic systems beneath volcanoes to accumulate reservoirs of eruptible sulfur large enough to create significant global environmental impacts. The project exploits the complex geochemical behavior of sulfur to track its movement from the liquid phase (silicate melt) into solid (mineral) and gas phases in magmatic systems. Sulfur is a polyvalent element that can change its valence state from S2- to S6+ over a narrow redox range relevant for terrestrial magmatic systems. This makes sulfur an excellent tracer for changes in magma redox conditions that may have played a critical role in the transport, enrichment, and release of sulfur during the 1257 Mt. Samalas eruption. The involved magmatic processes (e.g., degassing) should lead to predictable fractionations of sulfur isotopes in glasses and minerals, which will further constrain the dynamics of sulfur build-up at Samalas. The valence states of sulfur in minerals and glasses will be determined via X-ray absorption near-edge structure (XANES) spectroscopy, whereas sulfur isotope ratios will be measured by secondary ionization mass spectrometry (SIMS). This dovetailing of redox and isotope studies is a powerful new approach to addressing sulfur-related science questions. This project will serve as a blueprint for future studies of other volcanic systems and will have implications for magmatic sulfide ore-forming processes and crustal magma evolution of interest to the broader earth science community. ________________________________ Dr. Adrian Fiege Research Scientist and Laboratory Manager American Museum of Natural History Earth and Planetary Sciences Central Park West at 79th Street New York, NY 10024-5192, USA Phone: (+1) 212 769 5380; Fax: (+1) 212 769 5533 Email: afiege at amnh.org -------------- next part -------------- An HTML attachment was scrubbed...

Once at the portal page, enter your user name (e-mail address), and your password (membership number). Sincerely, Keith Putirka Ian Swainson *Editors Selections, May, 2018* *Review* *Biominerals ? A Review* On page 665 of this issue, Wysokowski et al. provide a comprehensive review of biomineralization processes, describing a range of mineral types and biological processes and structural diversity, with an emphasis on biosilica in viruses, bacteria, plants, diatoms, and sponges. Their work also illustrates how the structures and functions of biosilicifiers can inspire new forms of artificial biomineralization with far-ranging technological applications, including biomimicry. *Articles* *No Si in the Core?* On page 742 of this issue, Tateno et al. present new, high-pressure experimental results in the system Fe-Si-S. They find that crystalline metallic Fe is enriched in Si relative to S, compared to co-existing liquids. And so, with partial crystallization, especially at inner-core pressures (330 GPa), the solid, inner core is enriched in Si relative to the outer, liquid core. This finding may preclude Si as an important light alloying element if the 4.5% jump in density across the inner/outer core boundary requires an inner core that contains less Si than a presumably equilibrated liquid outer core. The authors find similar reasons to reject core compositions in the systems Fe-Si-C and Fe-Si-O, although they cannot exclude liquids in the system Fe-Si-H. It is not yet clear phase topologies within a more complex system (e.g., Fe-Si-O-S) might yet still allow a core that is Si-enriched, but if the core is a ternary system, then a Fe-Si-H ternary would be the only Si-bearing ternary that could explain the inner/outer core density change. *An Unexpected Basalt Source for the Huckleberry Ridge Tuff* On page 757 of this issue Swallow et al. examine mafic materials from the 2.08 Ma Huckleberry Ridge Tuff (HRT), the first and largest of the Yellowstone Plateau caldera-forming eruptions, and find a surprising result. The mafic materials that were involved in the HRT magmatic system are quite similar to much more recently erupted materials (ca. 5-10 ka) at the Craters of the Moon lava field in ID, and which also occur just west of the HRT caldera. These results yield a new perspective on the diversity and roles of various mafic magma inputs that likely provide the necessary thermal input to drive eruptions in the Yellowstone region. *A New EOS for Stishovite and CaCl2-structured SiO2 * On page 792 of this issue Fischer et al. conduct new high-pressure experiments to determine the equations of state for stishovite, and CaCl2-structured SiO2, a higher-P polymorph that, as shown by this new study, is stable at >68 or >78 GPa, along with expected subduction and ambient geotherms, respectively. The new EOSs also show that stishovite will indeed be denser than ambient mantle but the CaCl2 polymorph is likely to be buoyant relative to a pyrolite lower mantle, and that if Si is exsolved from the core into the mantle, the lowermost mantle might become locally saturated in SiO2, and in such a case, this SiO2 would add a degree of compositional buoyancy to its enclosing material. *Errors When Using V to Estimate Mantle fO2. * On page 819 of this issue Li presents new experiments to show that clinopyroxene/melt partition coefficients for V and Sc are sensitive to temperature, and possibly magmatic water contents, but that V and Sc are about equally affected and so are not fractionated from one another during melting. The result is that mantle *f*O2 estimates based on V only might be in error by nearly 2 orders of magnitude if *T*-effects are not accounted for, but that *f*O2 values based on V/Sc ratios are more likely to be valid, except perhaps for those cases where V is oxidized to V5+. *Letters* *Monazite, heal thyself* On page 824 , Seydoux-Guillaume et al. report a study using ion bombardment of LaPO4 monazite aims to understand why this mineral is never found amorphized. Simultaneous and sequential irradiations using Au and He ions at energies designed to simulate the recoil from nuclei undergoing alpha decay and the electronic energy loss of the alpha particle moving through the structure. This study shows that it is the latter that prevents amorphization in this mineral. This understanding is for predicting nuclear waste form performance and has implications for the application of geochronology and thermochronology in monazite. Keith Putirka Dept. Earth & Env.

T38. Interdisciplinary Investigations of Mantle-Crustal Mass Transfer Abstract: Understanding how the mantle and crust evolve and interact is important for the modeling of Earth's past. We encourage papers on the processes leading to mass transfer between the two chemically and rheologically distinct layers. Rationale: Unravelling the processes that control mass transfer between the upper mantle and lower crust is important for the modelling of the geological evolution of Earth and other rocky planets and protoplanets. Despite the scarcity of field areas where deep lithospheric rocks outcrop at the surface, significant advances have been made in understanding how the upper mantle and lower crust evolve and interact. The aim of this session is to bring together studies from different disciplines to discuss the latest results on the processes associated with the transfer of mass between the two chemically and rheologically distinct layers. Contributions from a variety of fields including, but not limited to, (experimental) petrology, geochemistry, geophysics and planetary science are invited. Abstract deadline: 14 August 2018.

This makes application of the zircon saturation thermometer enigmatic. On the other hand, zircon grown in laboratory granites may be peritectic rather than magmatic in view of experimental setup. In general, zircon can grow from magmatic melts after the fractional crystallization of Zr-poor minerals to sufficient extent. This can lead to the Zr oversaturation in granitic melts for growth of magmatic zircon in different stages. Nevertheless, antecrysts may grow at pressures higher than autocrysts do, making the growth of magmatic zircons at different depths. Crustal anataxis for granitic magmatism is commonly associated with peritectic reactions at supersolidus temperatures, resulting in growth of peritectic zircon prior to separation of granitic melts from their parental rocks. The peritectic reactions may take place at higher pressures than magma emplacement, and the peritectic zircon may grow in different stage during the crustal anataxis. In this case, the zircon growth has nothing to do with the Zr oversaturation in granitic melts. In fact, Zr is undersaturated in lowly evolved anatectic melts, so that no zircon can grow from them. With the fractional crystallization of Zr-poor minerals, nevertheless, the lowly evolved anatectic melts may become highly evolved ones during their ascent from anatectic sources to emplacement sites. Such melts behave like magmatic melts and thus can achieve the Zr oversaturation for zircon growth. However, it is uncertain whether the early stage of peritectic zircon would grow at greater depths than the late stage of peritectic zircon. The zircon saturation thermometer was experimentally calibrated on the basis of the zircon saturation in granitic melts, hypothesizing the Zr oversaturation for the crystallization of magmatic zircons. In those laboratory experiments, however, zircon may have grown via the mechanism of peritectic reactions, which has nothing to do with the zircon saturation in granitic melts. In this regard, it is critical to discriminate not only between antecrystic and autocrystic zircons but also between magmatic and peritectic zircons. In addition, natural granites may contain inherited (relict) zircons from parental rocks, and these relict zircons may be magmatic or peritectic. They should be excluded for the purpose of zircon saturation thermometry.

Dear all, I am looking for literature about the influence of pressure on the zircon saturation temperatures in granitic melts. I have been looking for experimental works trying to adjust the Watson & Harrison equation for the effect of pressure, but so far no luck. I would be grateful for any input on the topic!

We are offering a Magma Chamber Simulator short course at the Boston Goldschmidt meeting. By registering now, you can help us better plan the workshop. Many thanks, Wendy Bohrson Frank Spera, Jussi Heinonen ****** *Magma Chamber Simulator Workshop* *Goldschmidt 2018 * *Boston, Massachusetts* *August 11 and 12, 2018* ** *Conveners:*Wendy Bohrson, Central Washington University (bohrson at geology.cwu.edu) Frank Spera, University of California Santa Barbara (spera at ucsb.edu) Jussi Heinonen, University of Helsinki (jussi.s.heinonen at helsinki.fi ) Please join us for a two-day workshop on the *Magma Chamber Simulator (MCS)* on August 11 and 12. The Magma Chamber Simulator is an energy- and mass-constrained computer code (Bohrson et al. 2014) that simultaneously models recharge/magma mixing, crustal assimilation and crystal fractionation (RAFC). For a crustal magma body, MCS tracks the thermal, mass, and compositional (major and trace element, isotope, and phase equilibria) evolution as magma undergoes RAFC. During the first day of this workshop, participants will do hands-on activities that will familiarize them with running (e.g., input, steps to run code) the Magma Chamber Simulator (major and trace elements, radiogenic isotopes, and phase equilibria), and archiving and effectively utilizing output. The second day will involve modelling specific scenarios (e.g., RAFC, AFC, RFC) so participants can develop an understanding of how to effectively model their own data. Small group or one-on-one training will be available. *Please note that the trace element/isotope calculator will be a part of this workshop. *** We welcome petrologists at all levels: students, early career professionals and middle and later career professionals too! With training in this two-day workshop, students (undergraduate and graduate students) can master the use of the code. MCS can also be used in the classroom or lab, so we welcome those who are interested in integrating MCS into their petrology/geochemistry classes. If you have already taken an MCS workshop, please consider joining us in Boston for additional training; we will provide separate training to experienced users who wish to get feedback on specific questions/modelling challenges and/or who would like to learn how to implement the trace element/isotope module of MCS. For more information, go to: http://mcs.geol.ucsb.edu/. This web site has more information about the Magma Chamber Simulator, the MCS team, and a link to the Journal of Petrology site where Bohrson et al. can be found. *To register for the MCS shortcourse, go to the Goldschmidt conference website: **https://goldschmidt.info/2018/*** We welcome your questions; please email one of us. We hope to see you in Boston!

No one wants an unsafe work environment-particularly those that work in it every day. However, those that are charged with compliance (ie. administrators and haz consultants) almost always (IN OUR EXPERIENCE -ymmv) default to the most rigid interpretation/setting possible. But if you show that you are flexible and interested in making and keeping your work space safe then they may be open to compromise on some of the more onerous requirements. What ever you do - do not brush them off as meddling ignorant SOBs (only sadness comes from that path). Read all of their specifications and refs. An example: Many if not most dust refs are referenced to closed spaces with no air circulation which unless you lock a student & mill in a closet all day don?t really apply to an open lab space. It would be unfortunate to apply a closed space reg to an open lab or to a machine that could just as easily be run under a hood. just my 0.02 Andy Andrew.phelps at udri.udayton.edu 937.361.5346 > On Jun 6, 2018, at 1:08 PM, Pamela Burnley wrote: > > Hi all, > > Our campus is in the process of implementing Si dust policies and protocols and our department is in the cross-hairs.

A pretty ?common? set of REE minerals :) I found exactly the same growth style in carbonatite (often associated with barite in my case, but not always - see attached photo), and in many other contexts. It is also often found as an alteration product of other REE-minerals, like allanite. It looks that your EDS is set to cut the very low energy X-ray line, but if you set this limit to around 150-200 eV, you might be able to see the C Ka at around 250 eV. Unless of course you have a ?thick? window on your EDS, which would prevent detecting the C? Of course you will ?see? also the C peak from your coating, but you can ascertain there is definitely carbon in your mineral by comparing the intensity (at the same analytical conditions) in a C-free mineral such as the quartz or the pyrite. BTW, if you have some mineral to ID, and you know which elements are present, I can only recommend the excellent Athena Mineralogy database built by Pierre Perroud at the University of Geneva: http://athena.unige.ch/athena/mineral/search.html Cheers, Julien [cid:F78F465A-FAE2-446B-AA2A-8BCE5B7C201C at ethz.ch] ============================= Dr. Julien Allaz Head Assistant for EPMA & SEM ETH Zurich Inst. f?r Geochemie und Petrologie NW E 84.2 Clausiusstrasse 25 8092 Z?rich Switzerland Office: +41 44 632 37 20 http://geoloweb.ch ============================= On Jun 7, 2018, at 16:41, Giulio > wrote: Dear MSA talk subscriber, I need some help to identify a strange REE mineral that I found in an ore sample from Dale Head North, Lake District (UK).

T138. Magmas Assemble! Petrologic, Geochemical, Chronologic, and Geophysical Insights into the Architecture and Timescales of Magmatic Systems Abstract: This session focuses on new and innovative research aimed at understanding the evolution and assembly of magmatic systems. We invite contributions that address all aspects of these systems, including petrology, geochemistry, chronology, and geophysical perspectives.. Rationale: Over the last decade, an increasing number of studies have emphasized the non-steady state nature of magmatism in Phanerozoic orogenic belts. The geologic record indicates that both plutonic and volcanic systems often display episodic behavior, producing relatively short-lived magmatic "flare-up" events, followed by magmatic "lulls". The episodic nature of magmatic systems has also been established at the scale of a single pluton and volcanic edifice. Despite our current understanding, a number of processes remain relatively unconstrained at various tectonic settings, including the rates and volumes of magmatic additions to various structural levels (lower, middle, and upper crust), the relative contributions of mantle and crustal inputs, and the role of deformation in the assembly of magmatic systems. Thus, we seek contributions that provide insight into the assembly and architecture of ancient and modern magmatic systems in a variety of tectonic settings. We strongly encourage innovative approaches, and integrated studies, that link different perspectives and datasets. Abstract deadline: 14 August 2018.

Gysi (Colorado School of Mines), Daniel Harlov (GFZ Potsdam), Dmitrii A. Kulik (PSI, Switzerland), George D. Miron (PSI, Switzerland) This two-day NSF-sponsored workshop includes hands-on tutorials, lectures, and discussions about current numerical thermodynamic modeling methods, the databases required, and the experimental approaches used for studying metal transport associated with hydrothermal fluid-rock interaction in the crust coupled with examples from nature. The goal of this workshop is to link thermodynamic modeling and experimental approaches, and bring together a broad community interested in the interpretation of crustal metasomatism and ore-forming processes. Participants in the workshop will be provided with a memory stick, which contains the free software, thermodynamic databases, tutorials and relevant references covered. The workshop is intended for graduate students, researchers, and professionals whom want to learn how to apply the GEMS code package (http://gems.web.psi.ch) to geochemical modeling, as well as learn about how to use current experimental methods regarding fluid-rock equilibria at elevated P-T conditions. The GEMS code package is based on Gibbs energy minimization, and provides a user friendly framework for predicting mass transfer in complex non-ideal systems such as those associated with fluid-rock interaction and ore-forming processes. The workshop will cover: 1) fundamentals of the GEM-Selektor code package and thermodynamic databases for simulating fluid-rock systems; 2) the GEMSFITS parameter optimization tool for optimizing thermodynamic properties against experimental data; 3) an overview of experimental advances in the study of the stability and mobility of metasomatically induced and altered REE mineral phases in crustal rocks (e.g. monazite, xenotime, apatite, allanite, and titanite); 4) field case studies of metasomatism and associated REE mineral deposits. The first day of the workshop will cover 1) and 2). Here participants will learn the tools necessary to simulate fluid-rock equilibria at high P-T conditions and how to retrieve the parameters for geochemical modeling. These tools include the GEMS code package, which is supported by a tutorial series for different ore-forming processes (e.g., Greisen tin deposits), and by the MINES thermodynamic database (http://tdb.mines.edu). The second day of the workshop will cover 3) and 4). Here participants will be introduced to the experimental methods and field examples necessary for studying the solubility and speciation of REE in crustal fluids. Short discussion sessions will be included in order for the audience to find connections between the content of the workshop and their own particular interests in crustal fluid-rock interaction, including examples from both nature and experiments. More information about the workshop will be available on the web link above in due time.

ENKI is an on-going project funded by the National Science Foundation that provides software tools and a computational ecosystem for geochemical simulations that are based on thermodynamics and fluid dynamics. ENKI is aimed at students and researchers interested in using, creating, and maintaining models and in developing interconnected scientific modeling frameworks. We will introduce the capabilities of ENKI and demonstrate how thermodynamic calculations like phase diagrams, pseudosections, geothermobarometers, and mass transfer calculations (MELTS, EQ6, DEW) can be rapidly and easily computed. We will also show how thermochemical databases can be utilized to support fluid dynamical simulations. ENKI currently supports a number of thermodynamic databases and solution model collections, including those of Berman, Holland and Powell, Stixrude and Lithgow-Bertelloni, MELTS, DEW and SUPCRT. Participants will learn how these databases can be extended or recalibrated in light of new data or insights using the model calibration infrastructure provided by ENKI. Attendees will need a laptop for this workshop for real-time access to the ENKI server portal. -------------- next part -------------- An HTML attachment was scrubbed...

The information recorded in melt inclusions is unique because entrapped melts are physically shielded from most interactions with the external environment by the host mineral. Melt inclusion studies require careful sample preparation, application of state-of-the-art analytical methods, and meticulous attention to potential artifacts related to post-entrapment processes. As analytical techniques progress and our understanding of post-entrapment processes evolve, it is important that the rapidly growing melt inclusion community periodically assess the state of the field. This workshop provides those who study melt inclusions ? or would like to ? with the opportunity take stock of available analytical tools and protocols for dealing with complications such as post-entrapment crystallization, diffusive re-equilibration, and the presence of vapor bubbles. Specific topics to be discussed include: What are the relative strengths and weaknesses of Fourier transform infrared spectroscopy, secondary ion mass spectrometry, and laser-ablation inductively coupled plasma mass spectrometry? What are best practices for reconstructing total CO_2 when vapor bubbles are present? How reliable are H_2 O concentrations and the oxidation state of Fe recorded in melt inclusions? One objective of the workshop is to develop guidelines for publication of data from melt inclusion studies to be summarized in a collegial manuscript that the organizers will submit for publication shortly after the workshop. The workshop will consist of a series of invited talks followed by moderated discussion (in the style of a Gordon Conference). All workshop participants are strongly encouraged to contribute to a poster session scheduled for Saturday evening.

Biomineralization is the capability exhibited by many living organisms to produce hard tissues (shells, exoskeletons) with specific functions. In the framework of a project funded by the European Research Council (ERC Consolidator 3D-BioMat), our group [1] is exploring the possibilities offered by newly proposed x-ray and optical microscopies [2, 3] to progress in the understanding of the mechanisms underlying biomineralization. To this aim, we want to produce a structural description of bio- crystals obtained from calcareous marine shells and exploit our findings to guide in vitro organo-mineral crystallisation synthesis. The used microscopies, among which Bragg ptychography [2], will provide access to the detailed description of the crystalline properties of nanostructured crystals. Position The selected post-doctoral candidate will take active part into the ERC project, which requires to Design, implement and analyse Bragg ptychography experiments at synchrotron sources on biogenic and biomimetic samples, using the resources available in our group (numerical codes and super computer). Analyse the crystalline structure of selected bio-crystals and biomimetic samples using the microscopies available at Fresnel (optical ptychography and CARS) and other analytical tools (e.g., at synchrotron). Confront the structural findings to the available biomineralization scenarios. The selected postdoc should demonstrate a sound scientific background allowing him/her to conduct research activities in relation with most - but not necessary all ? parts of the above project description. He/she will work under the direct supervision of a CNRS senior scientist and will interact with other researchers in the team. He/she will have the opportunity to interact with physico-chemists and biologists also involved in the project. Requirements PhD degree with sound expertise in biomineralization, material structure analysis, coherent x-ray diffraction, crystallography or a related discipline. Experience working in x-ray coherent diffraction science or biomineralization is mandatory. Sound knowledge of computer programming, Highly rigorous data analysis skills.

Thus, analytics is not only concerned with individual analyses or analysis steps, but with an entire methodology. Predictive Analytics is a branch of data analytics that uses statistics, data mining, machine learning, modeling and artificial intelligence techniques to make assertions about the future or about currently unknown information. This session welcomes submission on any application of analytics which may be used to predict events, relationships, assertions, or any currently unknown information.

A good place to begin is with the book by Moore and Reynolds; with your knowledge of "conventional XRD methods", you can get by with just a few of the chapters. Purchase a few of the Clay Minerals Society Source Clays and make some measurements as a function of changing treatments. Before you know it, you'll have a good handle on clay mineral ID. Also be sure to keep in mind that most clay minerals do not have three-dimensionally ordered structures, so you cannot accurately model their diffraction patterns with virtually all Rietveld programs. You can find a 3-D structure of montmorillonite on the web, but it's a dream. Good luck, Dave On 6/22/2018 7:12 PM, Ratajeski, Kent wrote: > > Hi.?

It was Struve who sent Hermann to Russia in 1828, initially to promote his ideas and business. In his twenties (!) he was already elected a corresponding member (Chemistry) of the Russian Academy of Sciences. Besides promoting spas and organic chemistry, Hermann was a mineral enthusiast, travelled to the Caucasus and Urals, and was particularly keen on studying unknowns from the Urals. Hermann described pyrophyllite, chiolite (as Chiolith) and various other things. He died at 74 from intestinal inflammation and was buried in Moscow. More information is available here: https://biographiya.com/german-rudolf-iosif-rudolfovich/ (but you will need to translate it). Note also that in Russian sources, his last name is variable transliterated as ??????? or ???????.

AGU will be held in Washington, D.C. in 2018. *Regular Deadline: 1 August 2018, 11:59 P.M. EDT* 2018 AGU session V007. Basaltic magmatism: Constraints from trace elements. Session Description: Trace element geochemistry investigates the sensitivity of basaltic magma composition both to mantle melting processes and to recycling of elements in subduction zones. When combined with radiogenic isotopes, basalt geochemistry probes the rates and extents of Earth differentiation through time and illustrates the details of plate tectonic theory including testing mantle plume hypotheses. As basaltic magmatism provides both heat and chemical constituents to the atmosphere and hydrosphere, trace element geochemistry provides clues to the impact of volcanoes on the biosphere and implicates mantle melting as a suspect in mass extinctions. Consequently, we invite authors to contribute papers that use trace element geochemistry of mantle-derived lavas and mantle rocks to stimulate discussion of the role of basaltic magmatism in Earth history including as an agent of geobiological change.

Message-ID: Hi - can anyone recommend an in-class exercise where students use software (e.g. Vesta, Crystalmaker) to create a mineral? I could probably develop one from scratch, but I?d rather borrow someone else?s brain. My idea was simply to provide some basic information about ionic radii (or direct students to Shannon and Prewitt), then have students create crystal models on screen. I was thinking of working with halides, but only because cubic systems are easy to visualize geometrically and the chemistry is easy. My normal SERCh didn?t turn up anything particularly promising, but I could well have missed something. And, yes, I may well run the hoary ball-and-stick exercise, either instead of or in addition to the software exercise. I use Vesta, BTW.

Most labs with surface science tools (SIMS, Auger, RBS) usually (or used to) have an XPS instrument. These tools are usually found in the Materials Science or Chemistry departments of your local uni. An analytical method called micro- or spot-XPS came out a few years ago where the analysis spot was well under 1 mm diameter. Older XPS used a flood X-ray source so your specimens looked like old school powder X-ray slides. Might Raman identify the two phases? The coherence length/translational symmetry for a good Raman spectrum is about 1/10 of that needed for a good diffraction pattern. More Raman systems are available today than XPS (they tend to be easier to teach and operate that the vacuum-based system). If you do try Raman then use a red or IR beam to avoid beam heating on your fairly hydrous samples. Could be worth a try.

The sample size doesn't need to be too terribly large (you can probably get away with 10-50 mg), although larger samples will reduce measurement and titration errors. Basically, the idea here is that you could gauge the ferric/ferrous ratio and relate that to the mineral stoichiometries. You might want to check out a more recent article from The Geological Society of Finland of an article by Saikkonen & Rautiainen (1993)**. They discuss Wilson's technique, as well as two others. They suggest that you need at least 100 mg of sample for Wilson's method, but I think a careful analyst could do with less. Hope this helps. Best, Peter *Wilson, A.D., 1960.

You can collect spectra on exceedingly small samples, and the structure of the spectrum will tell you whether Fe2+ is present. The technique has been calibrated against methods like Mossbauer. This option, though, would require setting up beam time at a nearby synchrotron source (for you, probably ESRF or DESY). If you go this route, the paper below is a good recent reference.

The paper ?Beraunite: Refinement, comparative crystal chemistry, and selected bond valences? by Moore & Kampf (1992) which appeared in Zeitschrift fur Kristallographie 201, 263-281, may give you some idea. You can see the paper on the AMCSD website: http://rruff.geo.arizona.edu/AMS/result.php?mineral=beraunite The description paper on eleonorite IMA2015-003will appear, soon, in some international journal. The crystal structure may be reported in the paper. However, some considerations are required on the effects on the distance and valence calculation by the isomorphous substitutions for Fe3+ and/or Fe2+ by some cations with different size from Fe3+ and/or Fe3+, such as Mn3+ and Al3+.

Evolving perspectives of the Precambrian world: using combined theoretical and applied approaches to tackle problems at the intersection of geology, geobiology, and geochemistry. * *Brief description:* Tracking early Earth's dynamic surface evolution invites an integrated and cross-disciplinary multi-scale approach. We seek contributions from experimental, theoretical, field-, and/or laboratory-based studies that focus on deciphering key events in Precambrian Earth system evolution. *Rationale:* Tangled somewhere in the the preserved geologic record from the Precambrian supereon is the story of the interconnected evolution of early Earth?s surface environment and the emergence, diversification and radiation of nascent life. We envision assembling a session composed of a diverse group of geologists, geobiologists, and geochemists that pursue field- and laboratory-based experiments from the nano- to the macro-scale and/or apply modelling/proxy approaches to problems in Precambrian geology. In doing so, we seek to facilitate a dialogue between lab groups with varying techniques and tools used to answer long-standing questions that revolve around our understanding of nascent Earth and life viewed through the lens of deep time. *Abstract deadline:* August 14th, 2018. *Invited speakers: * Lizzy Trower (University of Colorado Boulder) Jena Johnson (University of Michigan) Timothy Gibson (McGill University) *Conveners:* Latisha Brengman (University of Minnesota - Duluth) Geoff Gilleaudeau (George Mason University) Thank you, Sincerely, Latisha and Geoff -- Latisha Ashley Brengman Assistant Professor University of Minnesota - Duluth Department of Earth and Environmental Sciences 1114 Kirby Drive, 221 Heller Hall Duluth, MN 55812 email: lbrengma at d.umn.edu phone: 1 (218) 726-7586 http://www.d.umn.edu/dees/faculty.html Virus-free. www.avg.com <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> -------------- next part -------------- An HTML attachment was scrubbed...

An alternative that is not affected at all by any of these parameters is Charge Distribution. The method does not calculate valences, but distributes them (formal oxidation number) as a function of the relative distances in each coordination polyhedron. It cannot differentiate atoms with the same valence, but it makes a clear difference between atoms with difference valence, even atoms of the same element, like Fe2+ vs. Fe3+.

(10-14 December). Session I.D.: 47391 Session Title: V021. Generation and Storage of Silicic Magmas in Hydrothermally Preconditioned Crust Section: Volcanology, Geochemistry and Petrology Conveners: Shane Rooyakkers (McGill University), Tamara Carley (Lafayette College), John Stix (McGill University) Abstract: The generation of low-?18O silicic magmas by melting of hydrothermally altered crust is a central but poorly understood process in some magmatic systems. Important examples include the Snake River Plain - Yellowstone hotspot track, where low- ? 18O rhyolite bodies have fed large caldera-forming eruptions, and Iceland, where generation of low- ? 18O rhyolite in mafic crust provides a controversial analogue for differentiation of Earth?s earliest silicic crust. Understanding the processes by which low- ? 18O silicic magmas are generated and stored has important and far-reaching implications, including insights into the genesis of magmatic-hydrothermal ore deposits and the evolution of continental crust, the mitigation of volcanic risk, and geothermal energy production. This session aims to connect diverse studies of silicic magmatism in hydrothermally altered crust. We invite submissions that address the genesis of low- ? 18O silicic magmas, the timescales and dynamics of these magma systems, and their economic and societal implications. Additional information on this session can be found here: https://agu.confex.com/agu/fm18/prelim.cgi/Session/47391 Abstract submissions are open here until 1 August: https://fallmeeting.agu.org/2018/abstract-submissions/ Best Regards, Shane Rooyakkers, Tamara Carley and John Stix ******************* Tamara Carley, Ph.D. Assistant Professor Department of Geology and Environmental Geosciences Lafayette College Phone: 610-330-5199 Email: carleyt at lafayette.edu From fdavis at d.umn.edu Tue Jun 26 13:09:24 2018 From: fdavis at d.umn.edu (Fred Davis) Date: Tue, 26 Jun 2018 12:09:24 -0500 Subject: [MSA-talk] AGU Fall Meeting Session V011.

The variation in redox potential between, and laterally within, these layers has profound consequences for geochemistry, geophysics, and geobiology. Redox reactions between minerals, melts, and fluids affect stable assemblages in the crust, mantle, and core. Varying concentrations of redox-sensitive elements can change the rheological properties of minerals by influencing defect concentrations. And chemical exchange between the surface and the interior has led to the evolution of physically distinct reservoirs on geologic timescales. This session hopes to foster conversations among a broad range of disciplines, including both geochemistry and geophysics. We encourage submissions describing experimental, modeling, and natural sample studies in igneous and metamorphic petrology, geochemistry, mineral physics, and seismology.* Note from AGU about this year?s meeting:* For the first time, the AGU Fall Meeting will be held in Washington, D.C., where we will mark the launch of AGU?s Centennial.

The cycling of volatile elements between a planet's surface and interior can be coupled to planetary-scale processes, and volatile elements within a planet's interior can influence a wide range of properties including redox state, conductivity, rheology, viscosity, melting, and element partitioning. This session aims to unite researchers from the fields of geochemistry, petrology, mineral physics, rock mechanics, seismology, and geodynamics whose work addresses the role of volatile elements in planetary interiors, the stability and cycling of volatile element-bearing phases at extreme conditions, and the influence of volatile elements on geological processes within the Earth and other terrestrial bodies.

Several features, imaged geophysically and constrained from xenoliths/exhumed mantle sections, characterize the upper mantle. These include complex mantle kinematics (e.g., flow around subduction-zones), enigmatic discontinuities (mid-lithospheric and lithosphere-asthenosphere discontinuities), as well as the cratons stability paradox (long-lived stability with evidence for deformation). These phenomena can be explained through evolution in microstructure (e.g., grain-size, crystallographic preferred orientation), the chemical environment (e.g., water content, chemistry, and structure of grain-boundaries), and/or the existence of melt. In this session, we explore the effect of microstructure and chemistry and their relationships with the strength, deformation mechanisms and tectonic history of the upper mantle. We invite abstracts from a variety of scientific ventures, e.g., rock deformation experiments, analysis of natural samples, and numerical models, to shed light on the microstructural and chemical effect on upper mantle strength and tectonic evolution. *Confirmed invited speakers:* Jessica Warren (U of Delaware) Nick Dygert (U of Tennessee ) This session is a co-organized by *Mineral and Rock Physics // Volcanology, Geochemistry, and Petrology // Tectonophysics * Best Regards, Yuval Boneh (Brown) Emily Chin (Scripps Institution of Oceanography, UC San Diego) Katharina Marquardt (Bayerisches Geoinstitut) -------------- next part -------------- An HTML attachment was scrubbed...

Sincerely, Keith Putirka Ian Swainson *Editors Selections, May, 2018* *Highlights & Breakthroughs* *Crystallography on Mars* On page 837 of this issue, Michael Velbel provides an overview (in a Highlights and Breakthrough paper) of two papers that appear in this issue, Morrison et al. (2018) on pages 848 and 857 of this issue. It will be no surprise to readers of this journal that analyses of crystal structures would be an essential component to the exploration of a new planet; Morrison et al. present the results of such, making use of the CheMin XRD on the Mars rover, Curiosity. Their crystallographic data and unit-cell calibrations are revising our understanding of mineral compositions on the Martian surface, with the potential of adding much precision to ideas of Martian sedimentary provenance, stratigraphy, diagenesis, and ultimate magmatic origin of individual mineral grains. *Articles* *You can Rely on Al in Qz* On page 839 of this issue, Tailby et al present new experimental results that show very slow diffusion rates of Al in quartz?slow enough that Al contents obtained during crystal growth will be almost invariably preserved above the tens-of-micrometers scale, irrespective of time. Diffusivities of Ti are similarly low, which means that zoning patterns of either element are quite likely to preserve the conditions of crystallization. If these elements preserve temperatures and cooling rates, they might also allow us to estimate crystal growth rates for quartz in natural systems, perhaps with a precision that is lacking for other minerals. *Mineral Chemistry from Crystallography* On page 848 of this issue, Morrison et al. present sets of equations that provide stunningly precise estimates of mineral compositions as calculated from X-ray diffraction data. As noted in Velbel?s Highlights and Breakthroughs article (p. 837, see above), this work was an important step in adding considerable precision to estimates of mineral compositions on Mars. But of course, there is nothing special about a martian origin, and these equations can and should be applied to terrestrial systems as well. This study may allow for much more cost-effective estimates of rock-forming mineral compositions compared to use of the electron microprobe, with the added benefit of having crystallographic information in the process. *A One-Mineral Tour of Arc Magmatism* On page 899 of this issue, Tecchiato et al. use the major and trace element contents and isotope ratios of clinopyroxene to trace magmatic transport and storage at the Capo Maragiu Volcanic District in Sardinia. The authors identify three types of clinopyroxenes, based on texture and composition, that track magma compositional evolution from Mg#(liq) 70 to Mg#(liq) 40. Especially intriguing are isotopic patterns with respect to Cpx Mg#, which allow the authors to show that, at least in this system, only the most mafic magmas are affected by assimilation of crustal components and that extensive and subsequent cooling and crystallization occurs as nearly a closed system. *Accelerating Supereruptions* On page 952 of this issue, Myers et al. obtain ascent rates for three different supereruptions from measurements of H2O and CO2 in re-entrants (melt inclusions that connect to enclosing glass) in quartz. Their case studies are from eastern California (Bishop Tuff), Yellowstone (Huckleberry Ridge Tuff), and New Zealand (Oruanui), and the ascent rates vary from 0.06 to 13 m/s with the lowest rates correlating to field relationships that indicate pauses in eruptive output. They find lower re-entrant H2O and CO2 contents compared to that of melt inclusions and model the contrasts as representing an accelerating of the magma during decompression, as magmas migrate from a storage chamber to an active conduit (on the order of hours to days). *Eckermannite replaces Glaucophane at High P* On page 989 of this issue, Howe et al. present the results of new experiments that indicate that above 40 kbar, glaucophane is likely to be replaced in blueschist facies metabasites by an amphibole that is a solid solution mix of eckermannite (80%) + katophorite (15%) + Mg-winchite (5%). The authors propose that the new amphibole is formed through the breakdown of jadeite + talc, with the consequent production of eckermannite, pyrope, coesite, and water. Despite the high Na/Al ratio of eckermannite, this phase is possibly stable in any system where jadeite and talc occur as precursors and should replace glaucophane in metabasite systems above 40 kbar. *Letters* *High-Pressure Humites* On page 1002 of this issue, Luoni et al. make use of thermodynamic models and recent experiments to quantify the otherwise ultra-high pressure (UHP) metamorphic paths of humite-bearing serpentinites. In the process, the authors show that UHP metamorphism in the western Alps was both polybaric and diachronous. This would appear to require a ?mosaic of tectonometamorphic units? that accreted over a range of depths and times and suggests that similarly dismembered ophiolites in other parts of the globe may represent composites of multiple slices of lithosphere, rather than coherent lithospheric sections.

Earth scientists play a vital role in shaping natural resource policies that ensure the availability of these minerals to society. These policies rely on knowledge of the stocks and flows of materials in natural and anthropogenic systems, in turn requiring an understanding of the geological processes that form mineral deposits and the industrial processes that transform mineral resources into useful materials. Future resource security will rely on both effective policy development and innovative technologies to realize the potential of Earth?s resources and make efficient use of above-ground stocks of materials in the built environment. This session provides an integrated approach to resolving some of these critical issues and welcomes contributions focusing on economic geology, mineral extraction, byproduct recovery, recycling, urban mining, and reprocessing of waste materials.

Invited Speakers: June Wicks (Johns Hopkins University) Yingwei Fei (Geophysical Laboratory, Carnegie Institution for Science) The Earth?s core, located more than 2900 km deep and with a pressure-temperature condition of 136-360 GPa and 4000-7000 K, constitutes 32 % of the total mass of the planet. The composition of the core is thought to be largely composed of an alloy of iron and nickel. However, discrepancy between density estimates from seismology and mineral physics requires the presence of lighter elements in both the liquid outer core and the solid inner core, with potentially different concentrations. There are several candidates including, but not limited to, hydrogen, carbon, nitrogen, oxygen, silicon, and sulfur. We seek contributions from geochemistry, experimental petrology, experimental and theoretical mineral physics that shed light into the composition and state of the Earth?s core, the light element content of the outer and inner core and their influences on elastic and transport properties of iron alloys.
