More Details About the Yamato 791132 Meteorite
The Yamato 791132 meteorite was discovered in 1979. It was recovered in Antarctica (-71.5, 35.66667). It has a mass of 1.9 grams.
Yamato 791132 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 791132’s official classification is LL5/6. The LL5/6 meteorite classification denotes a group of meteorites from the LL group of ordinary chondrites, known for their low iron and low metal content and relatively large chondrules. These meteorites exhibit characteristics of both petrologic type 5 and type 6, indicating they have undergone significant metamorphism, resulting in a blend of features like homogenized mineral compositions and the coarsening of secondary phases such as feldspar, bridging the characteristics of these two types.
The Yamato 791132 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.
