I'm a geochemist. My main interest is in-situ mass spectrometry, but I have a soft spot in my heart for thermodynamics, poetry, drillers, trees, bicycles, and cosmochemistry.

Phase diagram question
What do you guys use to plot ternary phase diagrams?
Does it run on a PC?
Is it Excel-compatible?
Does it do 3-D (4 component) systems?
Does it correctly plot error ellipses?
If the answer to all those is yes, please let me know.
I saw your question, and my inner petrologist hates having to plot ternary diagrams. I don't plot igneous geochemistry diagrams myself - when I collaborated with a petrologist in Vermont, his students all used Deltagraph, because it was the only plotting software that did ternary plots well at all. I've never found a good way to plot metamorphic ternary diagrams. (But I'm sure other people have - my metamorphic training was with a different crew of metamorphic petrologists than the ones who use ternary diagrams to visualize everything. In fact, I had one professor who had a personal vendetta against ternary diagrams because they were no good for thinking about slopes, and dT/dx was important to his research.)

That's what you use the 3-D ones for with either T or G on the z axis...
ReplyDeletei think golden software's grapher does those
