More Details About the Yamato 82195 Meteorite
The Yamato 82195 meteorite was discovered in 1982. It was recovered in Antarctica (-71.5, 35.66667). It has a mass of 25.24 grams.
Yamato 82195 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 82195’s official classification is LL3.7. The classification “LL3.7” denotes an ordinary chondrite from the LL group that is petrologic type 3. These chondrites, part of the LL group, are characterized by their low iron and metal content, fairly large chondrules, and distinctive oxygen isotope compositions. Petrologic type 3 indicates that this chondrite has abundant chondrules, minimal aqueous alteration, and unique mineral properties, including monoclinic low-Ca pyroxene grains with polysynthetic twinning.
The Yamato 82195 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.
