Sayh al Uhaymir 300 21°00′23.6′′N, 57°20′03.9′′E Al Wusta, Oman Find: 21 February 2004 Achondrite (lunar feldspathic regolith) History and physical characteristics: One gray-green individual of 152.6 g without fusion crust was discovered by Th. and P. Kurtz of Bartoschewitz natural science expedition team on a gravel plateau about 42 km SSE of Al Ghaba Resthouse (Adam County). Petrography: (R. Bartoschewitz, Bart; P. Appel and B. Mader, Kiel; W. Hsu, PMtOb) Polymict breccias (anorthosite, troctolitic anorthosite, noritic gabbro, and anorthositic gabbro), mineral fragments (anorthite, olivine, and pyroxenes), and glass veins are set in a fine-grained matrix of anorthositic olivine-gabbro composition. Accessoric minerals are kamacite, troilite, chromite, ulvöspinel, spinel, armalcolite, and ilmenite. Mineral compositions and geochemistry: (R. Bartoschewitz, Bart; P. Appel and B. Mader, Kiel; U. Krähenbühl, Bern; R. Niedergesaess, R. Pepelnik, and U. Reus, GKSS) Olivine (Fa26.8±5.2; mg# = 16.2–41.0), pyroxene (Fs25.6±4.7Wo11.0±5.6; mg# = 57–82), plagioclase (An95.8±0.6), metal (Ni = 39–116, Co = 11–5 [both mg/g]). Bulk Al2O3 = 20.4 wt%; FeO + MgO = 16.7 wt%; Th = 0.46; Sm = 1.1 ppm. The bulk FeO/MnO = 70.8, while the ratio in olivine and pyroxene are 83 and 49, respectively. Noble gas isotopes: (J. Park and K. Nagao, UTokE; R. Okazaki, KyuU) No solar gases, and low concentration of radiogenic isotope 4He. Magnetic susceptibility: (R. Bartoschewitz, Bart) log χ = 3.54 × 10−9 m3/kg. Classification: Achondrite (lunar feldspathic regolith breccia). Type specimen: A total of 20 g of sample is on deposit at Kiel. Th. and P. Kurtz hold the main mass. R. Bartoschewitz holds 5.3 g and a thin section. | ||||||||||||||
