Description

Over the years, NWA 3133 has scientifically been looked at as being a primitive achondrite, ordinary chondrite L7, Metachondrite, CR, CV3, and CV7. However, in 2019 it has been proposed that NWA 3133 might well be a CV8(1). This is a completely recrystallized member of the CV-clan of carbonaceous chondrites as a result of a progressive thermal metamorphism. It is composed of a fine-grained matrix of mostly olivine, orthopyroxene and lesser amount of plagioclase. According to the Meteoritical Bulletin Database, NWA 3133 is 1 of only 3 meteorites approved as a CV7. A n exceptional specimen ~ end-cut not often seen in this size .
