Writeup from MB 106:

Northwest Africa 11335 (NWA 11335)

(Northwest Africa)

Purchased: 2016 June

Classification: Carbonaceous chondrite (CO3)

History: Purchased by Ben Hoefnagels in June 2016 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Relatively small chondrules (apparent diameter 600±400 μm, N = 10), angular mineral fragments and some very fine grained CAI occur in a fine grained matrix (~40 vol.%, sepia brown in thin section).

Geochemistry: Olivine (Fa0.2-82.5, Cr2O3 in ferroan examples 0.12-0.31 wt.%), orthopyroxene (Fs0.7-1.1Wo0.7-3.3, N = 3), subcalcic augite (Fs0.6Wo29.2), augite (Fs0.8Wo36.4).

Classification: Carbonaceous chondrite (CO3). Chondrules are larger than in typical CO3.

Specimens: 20.3 g including one polished thin section at UWB; remainder with Mr. B. Hoefnagels.
