Writeup from MB 106:
Northwest Africa 11265 (NWA 11265)
Purchased: 2017 Jan
Classification: Carbonaceous chondrite (CV3)
History: Purchased by Martin Goff in January 2017 from a Moroccan dealer.
Petrography: (A. Irving and S. Kuehner, UWS) Ellipsoid-shaped granular chondrules (apparent diameter 730±500 µm, N=38) and elongate CAI (both showing preferred orientation) are set in a fine grained, fractured matrix (~45 vol.%, sepia brown in thin section). One CAI contains the assemblage corundum+gehlenite+spinel+perovskite.
Geochemistry: Olivine (Fa1.7-48.2, N = 3), orthopyroxene (Fs0.5-1.0Wo1.0-0.7, N = 3), subcalcic augite (Fs3.3Wo32.1; Fs15.5Wo25.3; N = 2)
Classification: Carbonaceous chondrite (CV3). Chondrule size and matrix abundance are slightly anomalous features. Probably paired with NWA 11256.
Specimens: 59.1 g including one polished thin section and one polished mount at UWB; remainder with Mr. M. Goff.
