Northwest Africa 1611 (NWA 1611)

(Northwest Africa)

Find date unknown

Classification: Iron meteorite (IAB-MG)

Petrography: Sample is an octahedrite, probably a coarse octahedrite with band-width poorly determined to be 1.6 mm + 0.7 mm or -0.5 mm. Sample consists almost entirely of kamacite. A few dark plessite fields, maybe 2% of the total area, are highly elongated. A mineral along some kamacite boundaries appears to be schreibersite.

Geochemistry: Co (mg/g) 4.68, Ni (mg/g) 67.4, Ga (µg/g) 84.9, Ge (µg/g) 303, As (µg/g) 13.5, Ir (µg/g) 1.81, Au (µg/g) 1.55.
