Writeup from MB 110:
Hinkley 34°59.12’N, 117°7.98’W California, United States Find: 2021 Feb 12 Classification: Ordinary chondrite (H4) History: On February 12, 2021, while searching for meteorites, Robert Verish found in gravel (between two blow-outs) a weathered, granular fragment of a stony meteorite. Physical characteristics: Initially considered to be a porous basalt because of a lack of a fusion-crust and a grayish-black groundmass that was sparkly. Recognized as a possible meteorite due to a solitary white chondrule, standing-out in high-relief, along the edge. Petrography: (D. Sheikh, FSU) Specimen is a chondrite containing chondrules (~500±100 µm), Fe-Ni metal, Fe-oxides, and chlorapatite. Geochemistry: Olivine (Fa19.0±0.4, range Fa18.2-19.4, n=10), Low-Ca Pyroxene (Fs17.0±0.6 Wo1.6±0.1, range Fs16.2-19.3 Wo1.0-1.8, n=24). Classification: Ordinary chondrite (H4). Specimens: 3.2 grams at UCLA; main mass with Verish. | ||||||||||||||||||||||||||||||||||||||
