Sayh al Uhaymir 511 (SaU 511) 20°53.764’N, 56°55.564’E Al Wusta, Oman Found: 20 Jan 2009 Classification: Ureilite History: Two fragments of 226.55 and 39.65 g were found during a search for meteorites by N. Dalcher, N. Greber, B. Hofmann, S. Lorenzetti and F. Zurfluh. Physical characteristics: Elongated brown stone and smaller fragment without fusion crust, combined mass 266.2 g. Petrography: (B. Hofmann, NMBE, F. Zurfluh IFGBE, E. Gnos, MHNGE): The rock shows an equigranular texture with 0.5-2 mm grain size and consists of olivine with subordinate Ca-rich pyroxene (pigeonite). The px/(ol+px)-ratio is ~0.2. Common carbon-platelets (up to 0.2 × 2 mm), showing some parallel orientation, consist of graphite and diamond (2-10 μm in size). Accessory phases are Fe and troilite. Glass inclusions occur in reduced rims of olivine grains. The shock grade of silicates is S2. Geochemistry: Olivine Fa21.2 to nearly pure forsterite in reduced rims; pigeonite Fs17.9Wo10.1. Bulk analysis shows Fe/Mn (wt) = 47.7, Ni = 1380 ppm. Specimens: All at NMBE. | ||||||||||||||||||||||||||||||||||||
