Writeup from MB 109:
Utting 33°59.20’N, 114°0.10’W Arizona, United States Find: 2020 Jan 28 Classification: Ordinary chondrite (H4) History: While searching for additional stones of the Bouse (L4-6) meteorite, a cluster of broken fragments was recovered by Robert Verish on January 28, 2020. Sample was taken from the 294 g specimen. Physical characteristics: Many stones are dark-brown, angular fragments. Some stones have one or more sides which appear to be a thick, desert-varnished patina, which is indistinguishable from a relict fusion-crust. A cut surface reveals an interior with small, matrix-supported chondrules of various colors. Petrography: (D. Sheikh, FSU) Chondrules moderately abundant (500±50 µm). Sample composed of olivine, low-Ca pyroxene, troilite, Fe-Ni metal, and Fe-oxides. Geochemistry: Olivine (Fa17.8±0.2, n=16), low-Ca Pyroxene (Fs16.1±0.4Wo1.2±0.2, n=25). Classification: Ordinary Chondrite (H4) Specimens: 27.2 grams at UCLA; main mass with Verish. | ||||||||||||||||||||||||||||||||||||
