Writeup from MB 85:
Dar al Gani 868 Libya Found 2000 spring Achondrite (ureilite) A 40.03 g stone was found in the spring of 2000 by an anonymous finder in the Libyan desert. Classification and mineralogy (H. Takeda, Chiba, and T. Ishii and M. Ohtsuki, UTok): has a typical ureilite texture consisting of anhedral to subhedral olivine and pigeonite (0.9– 3 mm across); carbonaceous material rims some grains or, in some cases, forms veins; one plate of graphite occurs within a large pigeonite crystal; olivine grains have homogeneous cores (Fa20.6) and reduced rims (Fa8) with high CaO contents (0.25–0.38 wt%); pigeonite, Fs16.8Wo7.5; less shocked than most ureilites; trace metal is mostly weathered to limonite. X-ray diffraction and reflected light microscopy (T. Nakamura and T. Nakamuta, KyuU) confirm the presence of fine-grained diamonds in a graphite lath. Specimens: main mass with anonymous finder; type specimens, 6.33 g, NSMT; 1.8 g, KyuU. | ||||||||||||||||
