Carbonaceous chondrite (CR2)

This black stone weighs 442.6 g. It is heavily fractured, with a portion fusion crusted. Classification and mineralogy (CAS): There are abundant large (1 - 4 mm in diameter), multi-layered and metal-rich type I chondrules, and a few type II chondrules. A spinel-rich inclusion (380 × 680 μm in diameter) was found. Metallic Fe-Ni is abundant (5.9 vol%), and occurs predominantly inside chondrules. Silicates are FeO-poor: olivine, Fa1.4±0.6, low-Ca pyroxene, Fs2.1±0.6. Accessory phases are phyllosilicates, sulfides and magnetite. Shock stage, S1; weathering grade, W1.
