Alatage Mountain 017 (AM 017)        41°41’13.4"N, 92°56’21.9"E

Xinjiang, China

Found: 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: 129.2 g (only 1 piece) no fusion curst, gray surface

Petrography: Chondrule types mainly include barred olivine, granular olivine, and porphyritic olivine-pyroxene. The matrix is coarse-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 50% of metal and sulfide is oxidized.

Geochemistry: Minerals are uniform. Olivine: Fa22.4±0.9 (n=10); low-Ca pyroxene: Fs118.8±0.9Wo1.8±0.8 (n=10)

Classification: Ordinary chondrite L5; S5; W2.

Specimens: 26 g sample and one thin section are deposited in GUT.
