P-T pseudosections of metamafic rocks in NCKFMASHTO system

  For melting metamafic rocks in NCKFMASHTO system, the comparison using the FIG. 4a in Green et al., 2016 JMG [1]. The same bulk composition and activity model are used. The result of GeoPS is identical with the original diagram, except in the Lower left corner. The result of GeoPS also is consistent with the results of THERIAK-DOMINO, although some assemblage boundaries are not smooth in the lower left corner of this diagram.
