Hi Kamil Ustaszewski,
Thank you for your information. (謝謝你！)
Do
you know if
there is a phase
equilibrium modeling for the sedimentary rock?

Hi Zhang Lei,
I think what you refer to is phase
equilibrium modeling (or, 'pseudosection' modeling) of metamorphic rock
assemblages. Such
modeling basically requires the whole rock chemical composition as input and
then calculates physically possible phase equilibria in a P-T space by
minimising the Gibbs free energy of each phase.
I recommend you use Christian de Capitani's
Theriak-Domino software package. It runs both in Unix environments, OSX and has
recently also been ported for WIN platforms,
There are other software packages like James
Connolly's PERPLE_X, which are capable of similar things.
You should be aware, however, that such kind
of pseudosection modeling is just that helps you in e.g., estimating the P-T
conditions of your rock assemblages. It doesn't free you from carefully
observing phase assemblages in thin sections under the microscope and analysing
mineral chemistry in an electron microprobe.
Cheers,
Kamil
