Northwest Africa 2198 is considered a “Valid” meteorite. “Valid” meteorites are typical meteorites with average weathering, while “relict” meteorites are those that have been extremely altered, either due to weathering over time or human intervention.
Northwest Africa 2198’s official classification is R4. 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.
The Northwest Africa 2198 meteorite is a “Found” meteorite. Meteorites are classified as “falls” if they were observed falling and recovered, while “finds” are those discovered later, often weathered by longer exposure to Earth’s environment and without a record of being seen as they fell.
