Petrography: (J. Gattacceca, B. Devouard, CEREGE) Brecciated igneous rock composed primarily of anorthitic plagioclase, and mm-sized poikilitic microgabbroic clasts with plagioclase chadacrysts set in olivine and pyroxene. Accessory minerals: metal, ulvöspinel, chromite. Barite, from terrestrial weathering, is present as veins.

Geochemistry: Plagioclase An93.4±2.7Ab6.3±2.5Or0.2±0.2 (n=4). Olivine (altered) Fo 43.5±5.9, FeO/MnO=143.4, analytical totals 90.9±2.2 (n=9). Orthopyroxene Fs26.0Wo9.0, Fs16.3Wo36.9, FeO/MnO = 50.8 (n=2). Chromite Cr#=0.73 (n=1).

Classification: Lunar (anorthosite). Contains microgabbroic clasts. Olivine, pigeonite and plagioclase are within the ferroan anorthositic suite (FAS) field defined by Warren (1993). Olivine has been altered on Earth, as indicated by the low analytical totals.
