Northwest Africa 13309 (NWA 13309)

(Northwest Africa)

Purchased: 2019 Sep

Classification: Ordinary chondrite (LL3.15)

History: Purchased by Mbark Arjdal in September 2019 from a dealer in Timbuktu, Mali.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed, fairly closely packed, relatively unequilibrated, glass-bearing chondrules (apparent diameter 900 ± 560 µm, N = 23) plus some isolated mineral clasts are set in a sparse opaque matrix rich in kamacite, taenite and troilite.

Geochemistry: Olivine (Fa16.2±8.3, range Fa0.6-26.9, N = 9; Cr2O3 in ferroan olivines 0.07-0.55 wt.%, mean 0.25±0.16 wt.%, N = 33), low-Ca pyroxene (Fs14.4±5.0Wo1.5±1.8, range Fs7.4-21.5Wo0.3-4.7, N = 5), subcalcic augite (Fs19.2Wo31.1), diopside (Fs1.2Wo44.5). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.51.

Classification: Ordinary chondrite (LL3.15). Chondrule sizes and magnetic susceptibility support an LL rather than L class. Subtype based on Cr2O3 contents of ferroan olivines per Figure 15 of Grossman and Brearley (2005).

Specimens: 38.2 g including one polished thin section at UWB; remainder with Mr. M.Arjdal
