CR7 Meteorite Classification

Class Description

The CR7 classification denotes a type of carbonaceous chondrite meteorite from the CR group, which has undergone significant metamorphic changes to the extent that it almost reached the melting point. Characterized by equilibrated minerals and barely discernible or absent chondrules, these meteorites belong to a class known for their near-solar magnesium-to-silicon ratios and oxygen isotopes that diverge from those found on Earth, featuring distinctive large chondrules with fewer refractory inclusions and a considerable presence of metal.
