Northwest Africa 13323 (NWA 13323)

(Northwest Africa)

Purchased: 2020 Feb

Classification: Carbonaceous chondrite (CK3)

History: Purchased by Mbark Arjdal in February 2020 from a dealer in Timbuktu, Mali.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed granular and some BO chondrules (apparent diameter 950 ± 460 µm, N = 23) plus sparse very fine grained, irregularly-shaped CAI are set in a fine grained matrix (~25 vol.%, deep brown in thin section) containing troilite, altered Cr-magnetite and rare taenite. Chondrules contain rounded grains of Cr-magnetite, some of which has been altered to red-brown iron hydroxides.

Geochemistry: Olivine (Fa17.9±18.4, range Fa0.3-44.1, N = 6), low-Ca pyroxene (Fs3.6±5.0Wo2.0±2.4, range Fs0.6-9.4Wo0.5-4.8, N = 3), pigeonite (Fs1.1Wo11.5), subcalcic augite (Fs1.4Wo29.2; Fs1.1Wo35.8; N = 2), diopside (Fs0.8Wo40.3), magnetite (Cr2O3 = 0.2-7.0 wt.%, N = 2).

Classification: Carbonaceous chondrite (CK3).

Specimens: 20.2 g including one polished thin section at UWB; remainder with Mr. M. ARJDAL.
