Writeup from MB 110:
Utting (b) 34°00.62’N, 113°55.34’W Arizona, United States Find: 2021 Jan 12 Classification: Ordinary chondrite (H4) History: A cluster of eight broken fragments were recovered by Anton Clemons and Robert Verish on January 12, 2021. Thin section was taken from the 4.3 g fragment. Physical characteristics: All the fragments are dark-brown, and angular. Some fragments have one or more sides that appear to be a relict fusion-crust, which is indistinguishable from a thick, desert-varnished patina. A cut surface reveals an interior with small, matrix-supported chondrules of various colors. Petrography: (D. Sheikh, FSU) Sample is an ordinary chondrite containing chondrules (Av. 450±50µm), Fe-Ni metal, and troilite. Geochemistry: Olivine (Fa19.8±0.9, range Fa18.8-21.9, n=17), Low-Ca Pyroxene (Fs17.5±0.6 Wo1.1±0.2, range Fs16.5-18.7 Wo0.7-1.3, n=17). Classification: Ordinary Chondrite (H4) Specimens: 21 grams and a thin section at UCLA; main mass with Verish. | ||||||||||||||||||||||||||||||||||||||
