Writeup from MB 109:

Pakepake 001 38°02.04’N, 83°39.36’E

Xinjiang, China

Find: 2019 Jan

Classification: Ordinary chondrite (L6)

History: The meteorite was Found by Pengli Chen who is a meteorite hunter in gobi desert near to Niya ruin in January, 2019. The Niya ruin is the historic site of the Jingjue Kingdom from the 2nd century B.C. to the 5th century A.D., in Minfeng county , Southern of Xinjiang, China.

Physical characteristics: Five specimens were recovered in the gobi desert. The individual specimen covered by black fusion crust weighs from 100 to 1500 g. The total mass is ~1.5 kg.

Petrography: (J. Ji, S. Hu and Y. Lin, IGGCAS) The meteorite has a typical chondritic texture, mainly composed of olivine, pyroxene, plagioclase, Fe-Ni metal and troilite, with minor other accessory minerals. The matrix displays a high degree of crystallization. Most plgioclase grains are larger than 50 mm in diameter. Some Fe-Ni metal grains have been oxidized along the rims. Shock melt veins and pocket were not identified across the section.

Geochemistry: Mineral compositions and geochemistry: (J. Ji, S. Hu and Y. Lin, IGGCAS) The olivine and pyroxene are homogeneous in chemical compositions. Olivine: Fa=24.2±0.7 (n=27), orthopyroxene: Fs_{20.8± 1.0}Wo_1.4±0.4(n=28)

Classification: (J. Ji, S. Hu and Y. Lin, IGGCAS) L6

Specimens: The main mass is held by Pengli Chen.
