Jiddat al Harasis 513 19°31.859'N, 55°10.787'E Zufar, Oman Found: 20 January 2008 Classification: Ordinary chondrite (LL7) History: A single stone was found during a search for meteorites by A. Al-Kathiri, E. Gnos, A. Grimberg, B. Hofmann and E. Janots. Physical characteristics: Rounded fully crusted single stone with a mass of 9.520 g, size 26 × 18 × 16 mm. This sample was found among numerous fragments of an unpaired ordinary chondrite (JaH 511). Petrography (E. Gnos, MHNGE; B. Hofmann, NMBE;): Heterogeneous texture consisting of coarse (up to 1.2 mm) low-Ca pyroxene (Fs23.5Wo3.8), recrystallized olivine (Fa28.6) and interstitial plagioclase (30-50 μm in size), common troilite, chromite, ilmenite (also as abundant exsolutions in chromite). Very little iron metal, heterogeneously distributed (single nugget up to 1 mm). Chondrule remnants are only faintly discernible. Porosity determined by alcohol saturation is 6.1 vol%. Troilite shows polycrystalline texture. Below the fusion crust is a pronounced rim of troilite melt impregnation. Shock stage S2. Geochemistry: Bulk Fe by XRF is 18.6%. Oxygen isotopes (I.A. Franchi and R.C. Greenwood, OU) δ17O = 4.07, δ18O = 5.73, and Δ17O = 1.07‰. Classification: Based on bulk mineralogy, mineral composition, bulk Fe and oxygen isotopes this is a highly metamorphosed LL chondrite, LL7 S1 W2. Specimens: All at NMBE. | ||||||||||||||||||||||||||||||||||||||
