Higashi-Akaishi UHP Peridotite Complex


The peridotites and included chromitite lenses are strongly deformed and folded near the garnet amphibolite body of the Gongen-goe area. Chromitite samples from the central part of the HA complex are far less deformed than the banded chromitites in the Gongen-goe area.
