Writeup from MB 94:
Northwest Africa 5152 Morocco Find: 2006 Achondrite (lunar, feldspathic breccia) History and physical characteristics: A 38 g complete stone was purchased in Rissani, Morocco, in 2007. The dark gray fusion crust is mostly eroded away by wind ablation. Petrography: (J. Wittke and T. Bunch, NAU) The vesiculated melt matrix regolith breccia contains an abundance of typical anorthositic lithologies that include anorthosites, anorthositic norites, troctolitic anorthosites, granulites, devitrified shock melts, breccia-in-breccias, in addition to mare basalts and mineral fragments. Interior weathering effects are minimal. Mineral compositions: Troctolite olivine, Fa27.6 (FeO/MnO = 95); maskelynitized plagioclase fragments, An91.2–97.6, norite orthopyroxene, Fs25.5Wo3.8 (FeO/MnO = 62); subophitic basalt pigeonite, Fs29.7Wo7.8. Bulk chemistry (R. Korotev, WUSL): Sc = 16.8 ppm; Cr = 1460 ppm; FeO = 9.03 wt%; Ni = 210 ppm; Ir = 210 ppm. Classification: Achondrite (lunar feldspathic breccia). Type specimen: A total of 7.7 g is on deposit at NAU. The main mass holder is anonymous. | ||||||||||||||||||||||
