Mount Yirtkuq Bulak 009 (MYB 009)        41°54.643’N, 90°32.716’E

Xinjiang, China

Find: October 2021

Classification: Iron meteorite (ungrouped)

History: Discovered by Aili and Xuefeng Yang in the desert, Xinjiang Province, in October 2021. Purchased by Ziyao Wang in Oct 2021

Physical characteristics: The single mass is approximately 4 cm long and 1-2 cm wide, and has a dark brown to black exterior.

Petrography: (C. Herd, UAb) Cut and etched surfaces show an equilibrated texture, consisting of numerous sub-mm kamacite grains with 120 degree mineral boundaries. No inclusions were observed and the meteorite appears to be quite fresh.

Geochemistry: ICP-MS data, using sample of North Chile (Filomena) as standard (C. Herd, P. Hill, and S. DuFrane UAb): Ni = 6.1, Co = 0.538 (both wt%); Ir = 0.004, Ga = 15, Ge = 67, As = 14, Sb = 0.3, Ru = 0.2, Re = 0.01, Os = 0.02, W = 1.5, Pt = 0.04, Cu = 186, Au = 0.9 (all μg/g).

Classification: (C. Herd and P. Hill, UAb): Iron, ungrouped. From a low-Ni group but Ir, Pt are too low for IIAB, Au is too low for IAB, and Ga and Ge are too low for any other group.

Specimens: Type specimen of 19.6 g at UAb. Main mass with ZWang.
