Writeup from MB 110:
Mount Yirtkuq Bulak 006 (MYB 006) 41°40’N, 90°30’E Xinjiang, China Find: April, 2021 Classification: Ordinary chondrite (H5) History: Many meteorite specimens were found by Pengli Chen, Bo Yu and Hua Li in Xiaoerbulake gobi desert of Turpan, Xinjiang, in April, 2021. The place, Xiaoerbulake, is named for the alkali and saline-rich feature in this area. Physical characteristics: More than 100 specimens were recovered in the Xiaoerbulake area. The individual specimen with partial to full black fusion crust weighs from 50 to 50000 g. Some large specimens have been broken into smaller pieces due to terrestrial weathering. The total mass exceeds 400 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. Few relict chondrules and some shock induced melt veins and pockets are observed in the polished sections. Most plgioclase grains are less than 50 mm in length. Some Fe-Ni metal grains have been transfomred into Fe-oxides at the margins. Geochemistry: Mineral compositions and geochemistry: (J. Ji, S. Hu and Y. Lin, IGGCAS ) The olivine and pyroxene are homogeneous in chemical compositions. Olivine: Fa=18.8±0.4 (n=47), orthopyroxene: Fs16.5±0.3Wo1.4±0.3 (n=46), clinopyroxene: Fs6.1±0.4Wo46.1±0.4 (n=3), plagioclase: An13.5±1.1Ab80.7±1.5 (n=32). Classification: ( J. Ji, S. Hu and Y. Lin, IGGCAS ) H5 Specimens: The main mass is held by Pengli Chen, Bo Yu, Hua Li | ||||||||||||||||||||||||||||||||||||
