 NWA 1982
Ungrouped achondrite related to Brachinite

A 368 g partially crusted stone was purchased in Rissani, Morocco in 2001. Classification and mineralogy (T. Bunch and J. Wittke, NAU): cataclastic pyroxenite with randomly dispersed metal grains; partial recrystallization of matrix and along fractures of large (up to 5 mm) orthopyroxene grains. Mineral modes: orthopyroxene, 68 vol.%; metal, 12%; plagioclase. 8%; troilite, 3%; ilmenite, 3%; phosphate, 2% spinels, 2%, and augite, 2%. Opx = Fs28Wo3; plagioclase = An90; spinel #1, Al2O3 = 61 wt%, MgO = 21.4%, FeO = 13.2%; spinel #2, Cr2O3 = 35.9%, Al2O3 = 33.0%, MgO = 17.9%, FeO = 13.1%; augite = Fs13Wo43. Oxygen isotope composition is somewhat outside the range of HED and closest to brachinites and IAB-IIICD irons (R. N. Clayton, UChi) : 18O = +3.78, 17O = +1.47, 17O = -0.50 . Cosmic ray exposure age (O. Eugster, UBE): of 18.6+-2.0 Ma falls on the major CRE cluster of the HED meteorites. Not paired with NWA 1827 or 1879 mesosiderite C. Shock level, S1. Weathering grade. W1. Specimens: Type specimens 13.8 g, NAU, 11.5 g with O. Eugster, UBE; main mass. Fectay. kamacite, Ni = 4.8 to 5.4 wt %; taenite, Ni = 31.4 to 36.7%;
