General information regarding this meteorite:
Carbonaceous meteorites are some of the most primitive and pristine meteorites and formed in oxygen-rich regions of the early solar system. CR carbonaceous chondrites are named after the 1824 Renazzo fall in Italy. As of March 2010, there are only 15 other NWA meteorites classified as CR2. CR2 meteorites have a high amount of metal and can typically display armored chondrules with nickel-iron or iron sulfide rims. Type 2 chondrites are characterized by abundant hydrated minerals and abundant fine-grained matrix.
