Yamato 86716 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.
Yamato 86716’s official classification is CM2. The “CM2” classification applies to a carbonaceous chondrite from the CM group, specifically of petrologic type 2, known for its small chondrules, significant fine-grained matrix, and plentiful hydrated minerals. This type of meteorite is defined by its high content of water-related minerals, the presence of nickel-bearing sulfides, and a considerable amount of small, round particles within its structure.
The Yamato 86716 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.
