GeoPS：

Below is a comparison of a pseudosection calculated with both program THERMOCALC and GeoPS

Theriak-Domino：

Below is a comparison of a pseudosection calculated with both program THERMOCALC and Theriak-Domino. Theriak-Domino, using the version of D.K. Tinkham，from：： http://dtinkham.net/peq.html

PerPle_X：

Below is a comparison of a pseudosection calculated with both program THERMOCALC and Perple_X. Perple_X 6.9.0 is used，the initial_resolution = [1/6 1/12]，the rest of options are default。 This result is similar with the benchmark of BL487 from the Perple_X website, see:http://www.perplex.ethz.ch/perplex/examples/bl478_benchmark.pdf
