Jiddat al Harasis 800 (JaH 800) 19°52.955’N, 56°39.780’E Al Wusta, Oman Found: 2011 Jan 22 Classification: Ureilite History: Four fragments with a combined mass of 1299.3 g were found during a search for meteorites by D. Abplanalp, U. Eggenberger, N. Federspiel, E. Gnos, B. Hofmann. Physical characteristics: Dark brown rock, strongly wind-eroded, no fusion crust. Petrography: (B. Hofmann, NMBE; E. Gnos, MHNGE; N. Greber, Bern): The rock shows an equigranular texture with a grainsize of 0.8-1.8 mm and consists of olivine and Ca-rich pyroxene (pigeonite). The px/(ol+px)-ratio is ~0.3. Common carbon-platelets (up to 1 mm) contain both graphite and diamond. Iron metal and rare troilite are only preserved as tiny inclusions in silicates. Abundant iron hydroxides at grain boundaries represents the bulk of completely oxidized metal. The shock grade of silicates is S2 (weak to strong undulose extincion). Silicates are weakly shocked. Strongly weathered. Geochemistry: Olivine Fa16.2±4.8 (3.7-19.1, n=15) with nearly pure forsterite in reduced rims; pigeonite 15.8±0.2 10.1±0.05 (n=10). Bulk analysis (ICP-OES) shows Fe/Mn (wt) = 51.4, Ni = 1460 ppm, Cr = 4960 ppm. Classification: Based on texture and mineralogy this is a ureilite. Specimens: All at NMBE. | ||||||||||||||||||||||||||||||||||
