Writeup from MB 107:

Mangui        22°2’6"N, 100°10’29"E

Yunnan, China

Confirmed fall: 1 June 2018

Classification: Ordinary chondrite (L6)

History: A fireball was witness seen around 9 pm in Xishuangbanna region of Yunnan province on June 1, 2018. A piece of meteorite with black fusion crust broke through a farmer’s silt-roofed house. A number of pieces of the meteorite varying from 1 to 100s of g have been found by several farmers from Manlun, Manyan, Manlang villages from June 2 to 9. The largest mass (for which coordinates are provided) weighs 1.28 kg and was found near the village of Mangui.

Physical characteristics: Most fragments are partially or fully covered with black fusion. Thin black shock-induced melt veins can be seen in the exposed areas of most samples.

Petrography: (S. Hu, Y. Lin and J. Ji, IGGCAS; Q. Zhou, NAOC; Li Ye, PMO) Equilibrated ordinary chondrite texture with poorly defined chondrules and strongly recrystallized matrix. Main minerals are olivine, pyroxene, plagioclase (maskelinized), Fe-Ni metal, and troilite, with minor chromite, chlorapatite and whitlockite. Secondary feldspar grains are 50-100 μm in size. Shock veins and melt pockets are observed.

Geochemistry: Mineral compositions and geochemistry: (S. Hu, Y. Lin and J. Ji, IGGCAS; Q. Zhou, NAOC) The olivine and pyroxene have homogeneous chemical compositions. Olivine Fa25.0±0.6 (n=109), orthopyroxene Fs21.1±0.3 Wo1.6±0.3 (n=66).

Classification: Ordinary chondrite, L6 S5

Specimens: Type specimens at PMO (45 g) and IGGCAS (35 g). Main mass with various Chinese meteorite collectors.
