Writeup from MB 99:

Northwest Africa 4702 (NWA 4702)

(Northwest Africa)

Purchased: 2007

Classification: Iron meteorite (ungrouped)

Petrography: A fresh looking sample; no octahedral pattern visible; thus an ataxite. On a deeply etched surface are fine, quasi-straight lines 0.05 to 0.1 mm long, 0.005 mm wide. They do not seem to be regularly oriented. These could be artifacts produced by the surface preparation.

Geochemistry: Co (mg/g) 4.37, Ni (mg/g) 54.3, Ga (µg/g) 44.6, Ge (µg/g) 110, As (µg/g) 6.00, Ir (µg/g) 0.093, Au (µg/g) 0.70.
