Yamato 790992 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 790992’s official classification is CO3.5. The “CO3.5” classification is assigned to a carbonaceous chondrite in the CO group, signifying it as a type 3 meteorite with a level of metamorphism that places it towards the higher end of this category. Characterized by a mix of small chondrules and minimal refractory inclusions, these meteorites exhibit a balance of abundant chondrules and minerals that are not yet fully equilibrated, including low-calcium pyroxene grains with distinctive twinning.
The Yamato 790992 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.
