Apollo 16 rocks: Classification and petrogenetic model

Abstract

The Apollo 16 rocks include cataclastic anorthosites, two varieties of unequilibrated breccia, two varieties of partly- to fully-equilibrated breccia, and a sequence of partially melted breccias. The latter, which dominate the Apollo 16 collection, include glass, devitrified glass, mesostasisolivine-plagioclase rock, mesostasis-rich basalt, basalt, and poikilitic rocks.
