Writeup from MB 104:

Northwest Africa 5928 (NWA 5928)

(Northwest Africa)

Purchased: 2009

Classification: Ureilite

History: The meteorite was purchased in 2009 from a local meteorite dealer in Agadir, Morocco.

Petrography: The meteorite displays a pronounced cumulate texture of up to 1-mm pigeonite and olivine crystals. It contains abundant flaky graphite; olivine displays characteristic reduced rims. It is less coarse-grained than NWA 6069, and thus the two meteorites are likely not paired.

Geochemistry: Reduced rims in olivine: Fa6.3-9.2; Cr2O3 in ol: ~0.6 wt%.
