Yamato 790199 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 790199’s official classification is H. The “H” group represents a category of ordinary chondrites notable for their high iron content and significant presence of siderophile (iron-loving) elements. Characterized by relatively small chondrules, approximately 0.3 millimeters in size, these meteorites have oxygen isotope compositions that align more closely with the terrestrial fractionation line compared to other ordinary chondrites.
The Yamato 790199 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.
