GeoPS: An interactive visual computing tool for thermodynamic modelling . . . GeoPS provides a wide range of phase equi-librium calculations based on a novel Gibbs energy minimization algorithm The algorithm provides for exceptionally robust and computationally efficient K E Y W O R D S metamorphism, phase diagram, phase equilibrium, thermodynamic modelling, visual computing Federal Institute of Technology, Zurich
GeoPS The following prerequisites are required: Microsoft NET Framework 4 8 (x86 and x64) If these components are already installed, you can launch the application now
Overview - geology. ren Overview What is GeoPS? Thermodynamic phase equilibrium modeling paves the way toward a quantitative understanding of geological processes such as metamorphism and magmatism It can forward simulate the metamorphic or magmatic system, to predict the stable mineral assemblages, compositions and various physical and chemical properties of given P-T conditions Phase equilibrium modeling also has
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 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中的Fig
