Northwest Africa 7719 (NWA 7719)

(Northwest Africa)

Purchased: 2012 Dec

Classification: Carbonaceous chondrite (CV3)

History: Purchased in Temara, Morocco by Adam Aaronson in August 2012.

Petrography: (A. Irving and S. Kuehner, UWS) Separated, chondrules (from 0.3 to 1.5 mm) and small, fine-grained CAIs in a light-brown, fine-grained ferroan matrix. Olivine, orthopyroxene, clinopyroxene are present but no metal was found. Fragments of CAI consist separately of hibonite, spinel, and andradite rimmed by clinopyroxene.

Geochemistry: Olivine (Fa0.4-56.8; Cr2O3 in ferroan olivine = 0.09-0.33 wt.%, mean = 0.16 wt.%, sd = 0.09 wt.%, N = 9), orthopyroxene (Fs1.2-2.6Wo0.8-0.4), clinopyroxene (Fs0.6-0.8Wo44.6-41.7).

Classification: Carbonaceous chondrite (CV3).

Specimens: A total of 20.3 g of material and one polished thin section are on deposit at UWB. Aaronson holds the main mass.
