Classification: Ureilite

History: Purchased by Blaine Reed in February 2019 from a Moroccan dealer at the Tucson Gem and Mineral Show.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Protogranular texture of non-equant olivine and pigeonite grains showing preferred dimensional orientation. Olivine has reduced, more magnesian rims associated with very fine grained Fe metal. No carbon phases were observed in the studied thin section.

Geochemistry: Olivine (cores Fa20.3-24.5, N = 13; rims Fa9.6-18.8, N = 6; Cr2O3 in all olivine = 0.6-0.8 wt.%), pigeonite (Fs11.8-19.5Wo10.2-12.4, N = 9; Fs10.9Wo15.2; Fs13.5Wo6.4).
