Physical characteristics: Sand-nodule of 1.71 g cemented by dark brown, magnetic, Ni-rich Fe-(hydr)oxides, containing millimeter-sized remnants of weathered meteorite. Petrography: Polished thin section shows terrestrial quartz sand grains cemented by maghemite and Fe-hydroxides. Inclusions up to 500 μm in size consist of pyroxene and feldspar. Geochemistry: (N. Greber, Bern) Ca-poor pyroxene: Fs7.6-12.2Wo0.6-6.5, median Fs10.4Wo1.9, Cr2O3 0.65 wt% (n=9). The sand-rich weathering rind has the following composition (XRF): Fe 23.1%, Ni 1.2%. Classification: Based on the presence of Ni-rich weathering products and remnants of pyroxene, this is a highly weathered meteorite, pyroxene compositions indicate possible pairing with nearby found ureilite Khawr al Fazra 018. Specimens: All material at MHNGE. | ||||||||||||||||||||||||||||||||||
