Dear George,

 

You can draw crystals of polysynthetically twinned calcite with VESTA.
Koichi says he can help you.

 

Best regards,

 

Ritsuro, NMNS, Tokyo

Subject: [MSA-talk] Polysynthetic twin drawings

 

I am trying to amass some EPS drawings of twinned crystals for an exhibit,
and I am having trouble finding or making (SHAPE) examples other than of
feldspar.  Does anyone have a vector drawing of, say, polysynthetically
twinned calcite that they would share with me.  I have had to customize
drawings of fluorite and pyritohedron penetration twins if you want to
trade.

Cheers,

George
