Hello everyone, I would be interested in trying to use TD to mimic fractional crystallization processes. Starting from an initial composition x, I’d like to create an incremental model, considering a stepwise variation of melt composition, T, P. Do you think this can be done in TD? Or, I don’t know, would you happen to know any plugin or program in TD capable of helping me?

Thank you in advance FS

im commend use special soft - MELTS or rhyolite-MELTS (https://magmasource.caltech.edu/ or https://melts.ofm-research.org/#First). in Theriak-Domino not used thermodynamic models for silicate melts (only for migmatites -HP database).

Thank you for your answer. From what I read on the melts website, pmelts can provide reliable results up to c.a 4 GPa. I would like to model at pressures higher than that. xmelts would be perfect, but it’s not yet been released.

For approximate solutions, I would use pMelts. may be contact with developer Paula M. Antoshechkina resolve you problem xmelts? Also i eccomend contact with Ilya Fomin http://chl-fomin.blogspot.com/
