Writeup from MB 106:
Jiddat al Harasis 818 (JaH 818) 19°44.439’N, 55°40.591’E Al Wusta, Oman Find: 11 Jan 2012 Classification: Carbonaceous chondrite (CV3) History: Found by Edwin Gnos, Beda Hofmann, Karl Wimmer, Elise Wimmer and Florian Zurfluh during a search for meteorites on January 11, 2012. Physical characteristics: Single wind-ablated stone of 19.36 g, no fusion crust preserved. Petrography: (E. Gnos, MHNGE and B. Hofmann, NMBE) The meteorite consists of up to 1.5 mm sized chondrules (approx. 45 vol%; average size 0.75±0.33 mm n=48) with partially recrystallized glass, CAIs (0.2-3.0 mm; approx. 5 vol%), and dark matrix (approx. 50 vol%). Magnetite is rather rare, troilite is largely oxidized. Some Fe-hydroxides probably resulted from oxidation of iron metal. Geochemistry: (N. Greber, Bern) Olivine compositions are Fa11.2-50.1, median Fa30.0 (n=4), pyroxene compositions are Fs0.8-5.7Wo0.9-5.7, median Fs1.0Wo1.3 (n=9). Oxygen isotopes: (R. Greenwood, OU) gave δ18O=5.43, δ17O=0.35, Δ17O= -2.47 (all per mil). Classification: CV3 based on petrography, matrix abundance, mean chondrule size, presence of large CAIs and oxygen isotopes. Specimens: All at NMBE. | ||||||||||||||||||||||||||||||||||||
