Abstract

Ferrosilite-fayalite bearing charnockite and biotite-hornblende bearing granite are exposed in Muhlig-Hofmannfjella, central Dronning Maud Land of East Antarctica. Both are interpreted as essentially parts of a single pluton in spite of their contrasting mineral assemblages. Based on petrologic and geochemical studies, it is proposed that H2O-undersaturated parent magma with igneous crustal component that fractionated under different oxygen fugacity conditions resulted in the Muhlig-Hofmannfjella granitoids.
