Writeup from MB 104:

Jiddat al Harasis 935 (JaH 935)        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 Fa24.1±18.2 (Fa0.1-50.1 n=34), pyroxene compositions (n=9) are Fs24.1±18.2Wo2.2±1.8 (Fs0.1-50.1Wo0.9-5.7). Oxygen isotopes: (R. Greenwood, OU) analysis of a sample leached with ethanolamine thioglycollate gave δ18O=3.67, δ17O=-1.14, Δ17O= -3.04.

Classification: CV3 based on petrography, variability of mineral compositions, matrix abundance, mean chondrule size, presence of large CAIs and oxygen isotopes. Unshocked (S1). Strongly weathered based on high degree of troilite oxidation.

Specimens: All at NMBE.
