Writeup from MB 107:
Gumu 33°10.17’N, 85°41.86’E Tibet, China Find, possible fall: June 25, 2018 Classification: Ordinary chondrite (H6) History: There was a rumor that a meteorite fall had happened in the Qiangtang region of Tibet. A local farmer first found a 0.5 kg meteorite on June 25, 2018. After that, 14 kg and 24.5 kg were collected in the same location on July 1 and Aug 5, 2018. Physical characteristics: About 20 pieces were found, with a total weight of ~39 kg. A few of them are covered with black fusion crust, and some show rusty spots. Petrography: (N. Wang, Y. Xu and Y. Lin, IGGCAS) It is an equilibrated oridinary chondrite, with homogeneous compositions of olivine and pyroxene. Most of the feldspars are >50 μm in size. The chondrules are very poorly delineated. Fe-Ni metal and troilite, with minor phosphate make up about 20% of the volume. Geochemistry: The chemical compositions of olivine and pyroxene are homogeneous across the thin section. Olivine: Fa19.1±1.2 (n=28), orthopyroxene: Fs16.3±0.9Wo1.4±0.4 (n=34) Classification: H6 (N. Wang, Y. Xu and Y. Lin, IGGCAS) Specimens: Main mass with P.
