Northwest Africa 3161 (NWA 3161)

NWA 3161 was discovered in the Sahara Desert in Northwest Africa in August, 2005. A total of 14 stones were found with a Total Known Weight of 2648g. Many of the individuals have relatively fresh fusion crust still present. NWA 3161 has been classified as an LL3.7 and displays a rich colourful interior with wall-to-wall chondrules. There is a little heterogeneity between the stones of this find. Some slices have just the chondrules while others have what looks like a different lithology. A few even have black inclusions such as the slice below. These appear to be most likely of a shock-darkened origin. This specimen is part of the Meteorites Australia Collection (MA.07.0048).
