Abstract

Small inclusions of hypersthene, augite, hornblende, and Fe-Ti oxides occur in plagioclase cores of granitic rocks from the Permian Barrington Tops granodiorite, New South Wales. A magmatic origin for the ferromagnesian inclusions demands a similar origin for their plagioclase host material. Plagioclase cores, therefore, cannot be used as unequivocal evidence of restite (residual high-grade metamorphic source material) in discussions of the genesis of granitic rocks.
