More Details About the Yamato 74160 Meteorite
The Yamato 74160 meteorite was discovered in 1974. It was recovered in Antarctica (-71.75278, 36.08889). It has a mass of 31.4 grams.
Yamato 74160 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 74160’s official classification is LL7. The classification “LL7” represents an ordinary chondrite from the LL group that is of petrologic type 7. In simple terms, this meteorite has undergone extensive metamorphism, almost reaching the point of melting, resulting in equilibrated minerals and blurred chondrule structures, although it’s important to note that the term “type 7” is not consistently used or widely accepted in scientific literature.
The Yamato 74160 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.
