Petrography: (T. Zhang, S. Hu and Y. Lin, IGGCAS) The meteorite consists of kamacite and minor taenite and schreibersite, with trace graphite. Different from Xinjiang (a) by the absence of rhomb-like micrometer-sized schreibersite grains.

Geochemistry: Mineral compositions and geochemistry: (G. Wang, GIGCAS, T. Zhang, S. Hu and Y. Lin, IGGCAS) Kamacite: 5.57-6.47 wt.% Ni, 0.04-0.18 wt% Co; Taenite: 9.73-41.5 wt.% Ni. Bulk compositions: Ni: 6.04 wt.%, Ga: 89.7 ppm, Ge: 318 ppm, Ir: 5.01 ppm.

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