Writeup from MB 103:
Northwest Africa 8443 (NWA 8443) Morocco Purchased: Feb 2013 Classification: Iron meteorite (IAB complex) History: A single specimen was purchased in February 2013 by Andreas Koppelt from a Moroccan dealer in Zagora. Physical characteristics: The 164.2 g mass is shield shaped and oriented with moderate weathering. The leading edge of the specimen is characterized by a ~7 × 7 mm circular depression. Petrography: Optical investigation reveals a well-developed Widmanstätten pattern consistent with a fine octahedrite. Plessite is common. Geochemistry: Bulk composition: INAA data (J. Duke and C. Herd, UAb): Ni=9.59±0.08 wt%, Co=0.504±0.003 wt%; Ir=0.83±0.04, Au=1.58±0.02, Ga=49.4±0.6, As=15.1±0.2, W=0.28±0.07, Re<0.1, Cr=40±13, Cu=292±22, Ge=115±22 (all μg/g). Classification: (C. Herd, UAb): IAB complex, fine octahedrite. Trace element composition suggestive of Udei Station grouplet of Wasson and Kallemeyn (2002). Specimens: Type specimen of 22.6 g, including slice used for INAA, at UAb. Most of the main mass remains with A. Koppelt. | ||||||||||||||||||||||||
