Breccia composed of lithic clasts and related crystalline debris dominated by anorthite and olivine with subordinate pigeonite and accessory low-Ti chromite, pentlandite and pervasive secondary barite granules. Geochemistry: Anorthite (An94.4-97.5Or0.2-0.0, N = 4), olivine (Fa19.0-45.6, FeO/MnO = 80-97, N = 5), pigeonite (Fs23.2-26.3Wo7.4-10.6, FeO/MnO = 42-50, N = 4). Troctolitic: A type of rock composition that typically contains plagioclase feldspar and olivine. Troctolite is a coarse-grained igneous rock. Anorthositic: Indicates a rock that is rich in anorthite, a type of plagioclase feldspar. Anorthosite is a common rock type found on the Moon's surface. Breccia: A type of rock that forms from the consolidation of fragmented material. Breccias are often formed by impact processes, where rocks are broken into fragments during collisions and then reassemble into a new rock. Classification: Lunar (troctolitic anorthositic breccia).
