Alatage Mountain 030 (AM 030)        41°41’19.9"N, 92°56’32.5"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: 49.7 g (only 1 piece) no fusion crust, gray surface

Petrography: The meteorite consists of olivine, orthopyroxene, and feldspar, associated with comparatively minor amounts of clinopyroxene, Fe-Ni, diopside, troilite, chromite and phosphate. In the section, the sizes of mineral are mostly <100 μm, and the sample shows a recrystallization texture. More than 40% of metal and sulfide are oxidized.

Geochemistry: Minerals are uniform. Olivine: Fa21.8±0.7 (n=24); low-Ca pyroxene: Fs19.1±2.1Wo3.4±1.5 (n=20)

Classification: Ordinary chondrite (L5); S5; W2

Specimens: 11 g sample and one thin section are deposited in GUT.
