P(論文) Ultrahigh-temperature (UHT) crustal metamorphism occurs where peak metamorphic temperatures of 900-1100℃ have been attained at pressures in the range 7-13 kbar. Mineral assemblages in metapelites that are constrained by experimentally-derived and calculated FMAS and KFMASH petrogenetic grids p...
