Writeup from MB 87:

Dhofar 836

Oman

Found 2000 August 15

Achondrite (ureilite)

A single stone weighing 995 g, and split into two pieces was found by an anonymous finder in the Dhofar region of Oman. Mineralogy and classification (H. Takeda, Chiba; T. Ishii and M. Ohtsuki, UTok.): medium-grained (1–2 mm), equigranular olivine (Fo79 core; Fo90 rim) and pigeonite (Ca10Mg74Fe16 to Ca11Mg71Fe19). Carbonaceous matter occurs as narrow, intergranular veins. Weakly shocked (S1), with rare mosaicism in olivine. The sample is weathered to brownish color in hand specimen, W1. Dho 836 was found only 6 km NW of Dho 837, but the two specimens differ in composition and texture, and so may not be paired. Specimens: type specimen 20.2 g NSMT; thin section, Chiba; main mass with anonymous finder.
