NWA 801, Carbonaceous CR2 Meteorite, Micromount


In 2001, NWA 801 was recovered from a Saharan strewnfield in Morocco. At first appearances, it was a relatively unremarkable, chondrule-rich meteorite covered in desert varnish. It was classified at the American Museum of Natural History has a carbonaceous chondrite of the CR2 type (a rare type at the time in 2001).

Carbonaceous chondrite (CR2)

History: M. Farmer and G. Hupe recovered a total of approximately 5 kg of many individuals and fragments from Zagora, Morocco. Many whole and sliced specimens have been sold over the last several years.

Physical characteristics: Many whole stones and fragments, all with desert varnish and brown/orange color. Numerous chondrules, many on the order of ~ 1 mm in apparent diameter, are visible.

Petrography: (G. Benedix and C. Smith, NHM) The thin section studied is dominated by millimeter-sized Type I PO and POP chondrules, which are often rimmed with and/or contain metallic Fe-Ni blebs. Metallic Fe-Ni also occurs as rounded, millimeter-sized grains within the matrix. Interstitial to chondrules and metal is a fine-grained matrix rich in phyllosilicate.Two Type II chondrules were also observed. Pervasive veins of rust occur throughout.

Classification:Carbonaceous chondrite (CR2); moderate to extensive weathering.

Type specimens: A total of 77.4 g of sample and two sections are on deposit at NHM. Farmer holds several grams, KCCU holds approximately 10 g, AMNH hold several grams
