Writeup from MB 109:

Northwest Africa 13019 (NWA 13019)

(Northwest Africa)

Purchased: 2016

Classification: Carbonaceous chondrite (CK6)

History: The meteorite was purchased from a meteorite dealer in Erfoud, Morocco.

Physical characteristics: Brownish rock without fusion crust.

Petrography: The meteorite predominantly consists of fine-grained recrystallized matrix mainly composed of ferroan olivine. Chondrules are sparse and only weakly defined. Minor phases include intermediate plagioclase (grain size about 80 μm), low-Ca pyroxene, Ca-pyroxene, and troilite. Cr-rich magnetite is abundant; metal is virtually absent.

Geochemistry: olivine: Fa30.0±0.1, FeO/MnO= 120±13, n=11; low-Ca pyroxene: Fs25.4±0.4Wo0.7±0.1, FeO/MnO= 72±8, n=14, Ca-pyroxene: Fs13.1±0.6Wo44.6±1.9, n=11; Cr2O3 in magnetite is about 3.0 wt%.
