Writeup from MB 106:

Alatage Mountain 014 (AM 014)        41°41’14.1"N, 92°56’16.8"E

Xinjiang, China

Find: 1 May 2013

Classification: Ordinary chondrite (L5)

History: An expedition found 42 meteorites between 30 April and 1 May 2013 in a 2.7 × 1.4 km area 80 km east of Alatage Mountain. The expedition included Bingkui Miao, Yangting Lin, Shijie Li, Deqiu Dai, Wenjie Shen, Sen Hu, Lei Kesi, Peng Wang, and Zhipeng Xia.

Physical characteristics: Total mass: 18.3 g (only 1 piece) no fusion crust, gray surface

Petrography: The matrix is fine-grained and the feldspars have sizes over 2 μm. Shock-induced metal-sulfide veins and melt pockets are pervasive. Many mineral grains are heavily fractured. More than 40% of metal and sulfide are oxidized. Possibly paired with Alatage Mountain 013. The wide shock veins (>200 μm) and ringwoodite indicate shock stage S5.

Geochemistry: Minerals are uniform. Olivine: Fa23.0±1.1 (n=7); low-Ca pyroxene: Fs18.9±0.4Wo1.7±0.3 (n=7)

Classification: Ordinary chondrite L5; S5; W2.

Specimens: 3 g sample and one thin section are deposited in GUT; 14 g at Hunan University of Science and Technology, China.
