Four stones together weighing 1502 grams were purchased from a Moroccan meteorite dealer in January 2017 and a type sample submitted for classification by myself. It was classified as a Carbonaceous meteorite from the CV class, a CV3. There were some anomalies noted by classifying scientist Tony Irving where he noted that – “These meteorites have a greater than typical proportion of matrix for CV3 chondrites, and the mean chondrule size is lower than is regarded as typical” and “The fact remains that the specimens that you have obtained are special members of the CV3 class”

Writeup from MB 106:

Northwest Africa 11265 (NWA 11265)

(Northwest Africa)

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.
