Introduction to Making Pseudosections with Perple_X
Click Hereto download my instruction manual for making pseudosections in Perple_X. I wrote this when I was modeling high PT paragneisses. The document takes the form of a worked example, going through the various aspects of making a pseudosection that I found useful. Additionally, there is information regarding bugs and other issues I have encountered.
This is a living document, and will be updated as I continue making pseudosections and as new versions of Perple_X become available. It is currently up-to-date. It is a bare-bones manual with a very simple bulk composition chosen for the example. Additional problems not addressed may be encountered for individual solution models, thermodynamic data-sets, and bulk compositions. Every rock is a bit different! The Yahoo Perple_X support group is a good place check whether these minor issues have been encountered and addressed previously.
