Sayh al Uhaymir 559 (SaU 559) 20°33.046’N, 56°39.336’E Al Wusta, Oman Found: Nov 2005 Classification: Ureilite History: During November 2005, John Blennert found a 107 g meteorite in the desert of Oman. Physical characteristics: Exterior of the stone is rough, with preferential (wind?) ablation of the pyroxene over olivine grains. Difficult to cut, requiring seven diamond blades and one week to slice the stone in half. Surface of the polished thin section is rough. Petrography: (L. Garvie, ASU) Typical ureilite dominated by roughly equal proportions of anhedral, fine- to medium-grained (0.5 to 1 mm) olivine and pyroxene. No graphite visible in the thin section. Extensive reduction of the olivine. Diamond abundant and confirmed by powder X-ray diffraction. Diamond clusters to 20 μm visible with a reflected-light microscope. Interstitial metal mostly altered to iron oxides. Geochemistry: Olivine and pyroxene more reduced than in typical ureilites. Olivine cores have Fa5.2±0.1, FeO/MnO = 11.5±0.7, Cr2O3 to 0.5 wt%, CaO to 0.3 wt%, n=13, rims to Fa0.5. Low-Ca pyroxene cores Fs4.7±0.1Wo4.89±0.04, n=7. Classification: Ureilite. Specimens: 32 g and one thin section at ASU. | ||||||||||||||||||||||||||||||||||||
