Writeup from MB 104:

Northwest Africa 6069 (NWA 6069)

(Northwest Africa)

Purchased: 2009

Classification: Ureilite

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

Petrography: The meteorite shows a cumulate texture of 0.1 to 1 mm olivine and pigeonite grains that typically join at 120 degree grain boundaries. Carbon is present as flaky graphite attesting to a rather low degree of shock metamorphism. Olivine displays characteristic reduced rims. It is more coarse-grained than NWA 5928, and thus the two meteorites are likely not paired.

Geochemistry: Reduced rims in olivine: Fa7.5-9.4; Cr2O3 in ol: ~1 wt%.
