Northwest Africa 5667 (NWA 5667)

(Northwest Africa)

Purchased: 2008

Classification: Ordinary chondrite (L3)

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

Physical characteristics: Dark grayish rock almost completely covered by fusion crust.

Petrography: The meteorite diplays a fresh grayish interior and shows a perfect chondritic texture with sharply defined, often flattened, and well packed chondrules (apparent mean diameter about 0.7 mm). The fine-grained matrix contains sulfides and FeNi metal. The meteorite is a breccia with up to 1.2 cm sized related L3 and black impact melt clasts.

Geochemistry: The mean concentration of Cr2O in ferroan olivine is 0.07±0.06 wt% (n=21).

Classification: L chondrite based on magnetic susceptibility, metal content, and apparent chondrule diameter.
