Pyroxene exsolution in mafic granulites from the Grove Mountains, East Antarctica: constraints on Pan-African metamorphic conditions

Exsolution textures were observed in clinopyroxenes in mafic granulites from the Grove Mountains, East Antarctica. The first generation of exsolution occurs only in subcalcic augite megacrysts, in which coarse orthopyroxene lamellae exsolved parallel to the (100) plane. Electron microprobe reintegra...
