Overview - geology. ren Overview Overview In order to demonstrate the reliability of GeoPS, we recalculated several phase diagrams of various rock types which are generated by THERMOCALC in published articles The results are consistent with that calculated by THERMOCALC, while using the same thermodynamic dataset and Solution models P-T pseudosections of metapelites in NCFMASOCR system MThe left figure is the Fig 9
White White MNNCKFMASHTO体系下计算结果比较 为验证GeoPS使用White et al ,2014 [1] [2] 的活度模型计算结果的可靠性，本次测试对利用GeoPS对White et al ,2014 [1:1] 中的图9进行重算，并与原图进行比较。计算所用热力学数据库为HP62（ds62），活度模型与THERMOCALC中的tc-6axNCKFMASHTOm45 txt文件中活度模型一致。左图为White 2014中
