| Writeup |
Writeup from MB 102:
Northwest Africa 7573 (NWA 7573) (Northwest Africa) Purchased: 2012 Classification: Carbonaceous chondrite (CK3) Petrography: Clearly discernible chondrules and abundant irregularly shaped CAIs set in a greenish-grayish groundmass. Chondrules often contain clear glass. Magnetite is dispersed in the fine-grained matrix and metal is virtually absent. Opaque phases dominated by Cr-rich magnetite. FeS uncommon. CAIs less abundant that in CV3 chondrites and also a high matrix/chondrule ratio argues for CK. | ||||||||||||||||||||||||||||
