Mount Yirtkuq Bulak 005 (MYB 005)        41°49’47.69"N, 90°26’10.14"E

Xinjiang, China

Find: 2021 Sep 10

Classification: Ordinary chondrite (H6, melt breccia)

History: (Ziyao Wang) Discovered by Aikeranmu Jiapaer in the desert near Xiao’er Bulake, Shanshan, on Sept. 10, 2021. He sold the meteorites to Ziyao Wang.

Physical characteristics: (Ziyao Wang and R. Bartoschewitz) Many brownish-yellow stones weighing between 560 g to below 10 g, total weight 6330 g. The surface shows heavy fractures that are filled with carbonates and quartz grains.

Petrography: (R. Bartoschewitz, Bart) The specimen consists of a brown stained chondrite clast beside a much finer grained dark-gray melt rock. The chondrite presents a strong recrystallized matrix with indistinct chondrules and metal and sulfide as small aggregates and melt veins.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa18.2±0.3 (n=12); pyroxene Fs16.7±0.6Wo1.2±0.2 (n=8); feldspar An14±1Or6±2 (n=3); chromite CRAL 85, FFM 72 (n=2). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 5.02

Classification: Ordinary chondrite (H6-melt breccia, W2)

Specimens: 20.9 g on deposit at Kiel, main mass with Ziyao Wang, and 117 g polished mount with Bart.
