Writeup from MB 109:
Cleghorn Lakes 34°15.396’N, 115°47.188’W California, USA Find: 2018 May 13 Classification: Ordinary chondrite (LL3) History: On May 13, 2018, while searching for meteorites, Robert Verish found in a saddle (formed by the pediment of two mountain ridges) a tight cluster of many fragments of a stony meteorite. Physical characteristics: Over 150 angular fragments were recovered (total over 1100 g) with many that could be physically paired, but not enough to reconstruct the original mass. Many fragments are missing, estimated to be 30%. A return trip to the find site resulted in only an additional 20 g. Petrography: (D. Sheikh, FSU) Abundant chondrules (900±50 μm) set in a fine-grained matrix containing accessory chromite, Fe oxides, and stained Fe-Ni metal. Geochemistry: Olivine (Fa0.7-44.3, n=53), Low-Ca Pyroxene (Fs1.2-29.9Wo0.2-3.9, n=83). Classification: Ordinary Chondrite (LL3) due to chondrule size and magnetic susceptibility. Specimens: 40 grams at UCLA; main mass with Verish. | ||||||||||||||||||||||||||||||||||||||||
