Northwest Africa 2679 (NWA 2679)

Morocco

Found: 2004

Classification: Iron meteorite (IAB-sHL)

Petrography (J. Wasson, UCLA): Observations based on two regions with  25 cm2 area. Attractive Widmanstätten pattern.  Kamacite bandwidth ~0.15 mm (Off).  Kamacite bands have high aspect ratios and are irregular in width, becoming much thicker (up to 0.5 mm) when they enclose small schreibersite grains.  Two large (8-9 mm) skeletal schreibersite masses are surrounded by swathing kamacite ~0.7 mm thick.  Modal abundance of schreibersite ~0.4 vol%.  No other inclusions recognized.

Geochemistry: Co (mg/g) 5.59, Ni (mg/g) 111.8, Ga (µg/g) 12.9, Ge (µg/g) <60, As (µg/g) 32.3, Ir (µg/g) 0.174, Au (µg/g) 3.28
