Petrogenesis of the phase 1 gabbro-diorite of the Miocene Mt Perkins Pluton, northwest Arizona: Implications for the role of mantle-derived mafic magmas in calc-alkaline magma evolution
… of four discrete magma pulses into a country rock of Precambrian orthogneiss. Phase 1 is a gabbro-diorite containing four rock groups: olivine-clinopyroxene cumulates, hornblende-plagioclase cumulates, homblende gabbro, and quartz diorite. Stage one of phases 2 and 3 evolved by a process of …
