Northwest Africa 3140

Morocco

Purchased 2004 April

Achondrite (ureilite)

A 750 g dense, broken, greenish-grey stone (one large and several smaller pieces) was purchased in Tagounite from a Moroccan dealer by A. and G. Hupé (xHupé) in 2004 April.  Classification and mineralogy (A. Irving and S. Kuehner, UWS): Mainly olivine (core Fa22.2, CaO = 0.31 wt.%, MnO = 0.43 wt.%, Cr2O3 = 0.53 wt.%) with subordinate pigeonite (core Fs17.9Wo9.1, Cr2O3 = 1.26 wt.%, FeO/MnO = 26.2) and interstitial metal plus finely granular carbon phases (including diamond, judging from difficulties in cutting this specimen). The rims of grains of both olivine (Fa13.8, CaO = 0.35 wt.%, MnO = 0.49 wt.%, Cr2O3 = 0.43 wt.%) and pigeonite (Fs12.1Wo9.4, Cr2O3 = 1.25 wt.%, FeO/MnO = 16.4) exhibit characteristic reduced compositions against interstitial matrix.  Specimens: type specimen, 20 g, and one polished thin section, UWS; main mass, xHupé.
