Writeup from MB 106:

Bayin Gobi 001 (BG 001)        41°19.03’N, 105°20.57’E

Nei Mongol, China

Find: 1 May 2015

Classification: Ordinary chondrite (L5)

History: On May 1, 2015, Xueming Tang, a Chinese amatuer, and his companions found this sample in the Bayin Gobi desert. He then sent a 20 g sample, cut from the main rock, to GUT for classification and description. The finder retained the main mass.

Physical characteristics: Total mass: 35 kg (1 piece), no fusion crust, black-brown surface, smoky-gray colored interior.

Petrography: The meteorite consists mainly of a medium-grained granular aggregate of olivine, low-Ca pyroxene and feldspar, with minor amounts of Fe-Ni alloy and troilite. The chondrules are moderately abundant and are readily defined.

Geochemistry: Minerals are uniform. Olivine: Fa=26.1±0.7 (n=12); low-Ca pyroxene: Fs=21.9±0.3Wo=1.6±0.3 (n=11).

Classification: Ordinary chondrite (L5); S2; W1.

Specimens: About 20 g sample and one thin sections are deposited in GUT.
