Northwest Africa 7428 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 7428’s official classification is L6-melt breccia. The L6-melt breccia classification is used for a specific type of meteorite from the L group of ordinary chondrites, known for their moderate iron content and moderately sized chondrules. This meteorite is categorized as petrologic type 6, indicating it has undergone extensive metamorphism, leading to uniform mineral compositions and less distinct chondrules, and it is distinctive as a breccia, with a matrix formed from material that has melted, setting it apart from typical type 6 chondrites.
The Northwest Africa 7428 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.
