Mantle-derived, UHP garnet pyroxenite and eclogite in the Moldanubian Gfohl nappe, Bohemian Massif : A geochemical review, new P-T determinations and tectonic interpretation

Abstract

Garnet pyroxenites and eclogites were formed by UHP accumulation of grnt + cpx (+- trapped melt) from transient melt in subcontinental litosphere.The source of melts was subducted, hydrothermally altered oceanic crust
