Meteorite "Dhofar 837"

Quick Overview

"Dhofar 837

Oman

Found 2000 spring

Achondrite (ureilite)

A single stone weighing 900.1 g, and split into two pieces was found by an anonymous finder in August 2000 in the Dhofar region of Oman. Mineralogy and classification (H. Takeda, Chiba; T. Ishii and M. Ohtsuki, UTok): A few medium-grained olivine and pigeonite grains (up to 2.1 × 1.5 mm in size) are set in a texture of smaller grained minerals with carbonaceous material and fine metal veins at grain boundaries. Olivine grains (75 vol%) are more abundant than pigeonite (20%). The metal veins are less than 5 vol%. The pigeonite composition Ca5Mg76Fe19 is uniform and the Fo values of olivine range from 78 to 79. Weakly shocked (S1-2). The sample is weathered to brownish color in hand specimen, W1. Dho 837 was found only 6 km SE of Dho 836, but the two specimens differ in composition and texture, and so may not be paired. Dho 837 has some textural similarities to Dho 295, but as the two specimens have very different Fe atomic %, and were found around 113 km apart, they are not necessarily paired. Specimens: type specimen 20.8 g NSMT; thin sections, Chiba, KyuU; main mass with anonymous finder."
