R4 Meteorite Classification

Class Description

The R4 classification is assigned to a unique type of meteorite known as an R chondrite, which stands out from other chondrite groups due to its specific chemical composition and highly oxidized minerals. This meteorite is classified as type 4, indicating it has undergone a moderate level of metamorphism, leading to the homogenization of its olivine minerals and the recrystallization of its finer matrix, while maintaining a high presence of chondrules.
