More Details About the Yamato 82179 Meteorite
The Yamato 82179 meteorite was discovered in 1982. It was recovered in Antarctica (-71.5, 35.66667). It has a mass of 56.02 grams.
Yamato 82179 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 82179’s official classification is LL3.5. The classification “LL3.5” refers to an ordinary chondrite from the LL group that is petrologic type 3. Ordinary chondrites from the LL group are characterized by their low iron and low metal content, fairly large chondrules, and oxygen isotope compositions distinct from other chondrites. Petrologic type 3 indicates that this chondrite has abundant chondrules, minimal aqueous alteration, and distinctive mineral properties, including monoclinic low-Ca pyroxene grains with polysynthetic twinning.
The Yamato 82179 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.
