Northwest Africa

Purchased 2004 August

Achondrite (ureilite)

A single stone of 123 g was purchased in Erfoud, Morocco. Description and classification (J. Wittke and T. Bunch, NAU): typical ureilite that mostly consists of medium to coarse-grained olivine and pigeonite. Extensive reduction (R5) has affected more than 60 vol. % of all olivine and ~15 vol. % of pigeonite. Carbonaceous-metal-silicate masses are also extensively developed. Olivine cores, Fa12.3 (FeO/MnO = 19), Cr2O3 = 0.60 wt. %; olivine rims, down to Fa1.2; pigeonite cores, Fs10.9Wo5.2. Also, interstitial Al-rich augite, K-rich glass, Fe3C, and probable diamond. Interstitial metal is mostly weathered to various iron oxides; no observable primary graphite. Low weathering grade and lightly shocked (S2). Specimens: type sample, 21.1 g, NAU; main mass, Birdsell.
