P-T pseudosections of metapelites in MnNCKFMASHTO system

  To demonstrate the reliability of GeoPS while using the activity model of White et al., 2014[1] [2], the figure 9 of White et al. 2014 was reproduced by GeoPS as an example. The used thermodynamic database is hp62 (ds62), and the activity model is consistent with that in tc-6axnckfmashtom45.txt file in THERMOCALC. The left figure is from the Fig. 9 in white 2014, and the right one is created by GeoPS. They are completely consistent.
