Writeup from MB 100:
Northwest Africa 6932 (NWA 6932) (Northwest Africa) Found: 2008 Classification: Iron meteorite (ungrouped) History: Reportedly found in the Algerian Desert Petrography: Plessitic octahedrite with isolated (<5% of area) sparks and spindles of kamacite; longest bands are ~8 mm long and 0.2 mm wide. The material may be reheated; the fine plessite has a granular appearance and there are small dark ellipses that may reflect resorption of phosphide. No heat altered rim was recognized. Stucture Opl. Geochemistry: Composition: 6.84 mg/g Co, 122.7 mg/g Ni, 9.45 μg/g Ga, 102 μg/g Ge, 6.45 μg/g As, 7.87 μg/g Ir, and 0.78 μg/g Au. The meteorite has no close compositional relatives. For example, in the Co range from 6.2 to 7.5 mg/g, no ungrouped iron has a Au content within 20% and only Guin and Laurens County have Ir contents within 20% of that in this iron, but these irons differ in several other compositional respects. Specimens: Type specimen, 318.7 g, UCLA; main mass DPitt. | ||||||||||||||||||||||
