Writeup from MB 109:

Tazhong 001        39°21.14’N, 83°15.49’E

Xinjiang, China

Find: 2019 Jan

Classification: Ordinary chondrite (H5/6)

History: The meteorite was found by Pengli Chen who is a meteorite hunter in middle Taklimakan desert near to Tazhong town, Southern Xinjiang, in January, 2019. Tazhong town was built in desert because of the exploration of oil.

Physical characteristics: Ten specimens were collected in the Taklimakan desert. The specimens are covered by black fusion crust. The partial fusion crust surface is cemented by sand.The masses of specimens are in a range 50 to 1000 g. The total mass is ~ 2 kg.

Petrography: (J. Ji, S. Hu and Y. Lin, IGGCAS)The meteorite has a typical chondritic texture. Few relict chondrules are observed across the section, ranging up to ~1 mm in diameter. The major constituent minerals are olivine, pyroxene, plagioclase, Fe-Ni metal, and troilite, with minor chromite and phosphates. Some plgioclase grains are larger than 50 mm in diameter.Fe-Ni metal grains have been partially oxidized.

Geochemistry: Mineral compositions and geochemistry: (J. Ji, S. Hu and Y. Lin, IGGCAS) The olivine and pyroxene are homogeneous in chemical compositions. Olivine: Fa=17.8±0.9 (n=57), orthopyroxene: Fs15.5± 1.1Wo1.1±0.46(n=43)

Classification: (J. Ji, S. Hu and Y. Lin, IGGCAS) H5/6

Specimens: The main mass is held by Pengli Chen.
