Writeup from MB 104:

Northwest Africa 8480 (NWA 8480)

(Northwest Africa)

Purchased: 2012 Dec

Classification: Iron meteorite

History: Purchased in Agadir in December 2012

Physical characteristics: A single dark smooth ellipsoidal mass.

Petrography: (J. Gattacceca, CEREGE): Quench texture with dendritic/cellular metallic FeNi set in a troilite matrix. Typical metal islands are 100-150 μm in size. 67 vol% FeNi, 33 vol% FeS. Spherical droplets of phosphates up to 50 μm in diameter. Rare euhedral chromite up to 50 μm.

Geochemistry: Metal Fe93Ni6.4Co0.6 (N=5), Co content of metal (0.61 wt%), sulfides Fe0.50S0.50 (N=3), chromite Cr#=1.00, FeO/MnO=70 (N=4), phosphate Fe3.05P1.95O8 (N=2).

Classification: Iron. Minimal weathering. This meteorite is probably a nodule from a larger one. Co content of metal and MnO/MnO of chromite are a priori not compatible with provenance from an ordinary chondrite.

Specimens: 5.5 g in CEREGE. Main mass with Labenne.
