Writeup from MB 104:

Xinjiang (a)        47°52’N, 88°7’E

Xinjiang, China

Find: 2003 Aug

Classification: Iron meteorite (IAB-MG)

History: The meteorite was purchased from an anonymous finder in Aletai, Xinjiang province.

Physical characteristics: An irregular piece of iron, with concave surface feature.

Petrography: (T. Zhang, S. Hu and Y. Lin, IGGCAS) The iron contains a low abundance of taenite, and show plessitic intergrowths of kamacite and taenite. Schreibersite has two types of occurrence, as coarse and elongated grains between kamacite boundaries, and as abundant rhomb-like micrometer-sized grains in kamacite. Minor dauberrite, troilite, sphalerite and graphite were found.

Geochemistry: Mineral compositions and geochemistry: (G. Wang, GIGCAS, T. Zhang, S. Hu and Y. Lin, IGGCAS) Kamacite: 5.01-6.80 wt.% Ni, 0.08-0.18 wt% Co; Taenite: 9.77-49.2 wt.% Ni. Bulk compositions: Ni: 6.22 wt.%, Ga: 94.9 ppm, Ge: 321 ppm, Ir: 4.43 ppm.

Classification: (G. Wang, GIGCAS, T. Zhan, S. Hu and Y. Lin, IGGCAS) IAB, main group

Specimens: The main mass is held by Zhigan Li.
