Shişr 176 18°13.207’N, 53°49.258’E Zufar, Oman Found: 14 Oct 2010 Classification: Ordinary chondrite (L6) History: Eleven, fresh, complete meteorites found near Shisr, Oman. Physical characteristics: Stones mostly covered by black fusion crust, several are oriented. Petrography: Łukasz Karwowski, USil) Olivine in chondrules and small olivine grains outside of chondrules have similar compositions with low Fa. Larger olivine grains are texturally zoned: outer zones are richer with Fa26.45. Low-Ca pyroxene is usually accompanied by Ca pyroxene. Feldspar is recrystalized, sometimes with albitic twinning. No maskelynite was found. Chondrules generally highly recrystalized. Barred chondrule and radial pyroxene chondrules were found. Chondrules to 2 mm. Cl-bearing apatite and merrillite present. Opaque minerals are represented by troilite, kamacite, taenite, and chromite. Tetratenite occurs as separate grains. Small copper grains were found in taenite kamacite and troilite. Geochemistry: Łukasz Karwowski, USil) Olivine Fa24.7-26.5; low-Ca pyroxene Fs21.3-21.9Wo0.9-2.1: high-Ca pyroxene Fs7.6-8.5Wo44.5-46.2; feldspar Ab82.0-86.8Or2.8-7.6; kamacite: 6.3-6.8 at% Ni; 0.66-0.69 at% Co, troilite Fe49.6-49.4S50.0-50.2; Accessory: chromite, Cl-apatite, merrillite, tetrataenite (separate grains), metallic Cu in taenite, kamacite and troilite. Classification: Łukasz Karwowski, USil) Olivine (Fa24.69-26.45), low-Ca pyroxene (Fs21.27-21.86) identify this stone as an L6. Sparse chondrules with diffuse boundaries further indicate that it is an L6 chondrite.
