More Details About the Asuka 87346 Meteorite
The Asuka 87346 meteorite was discovered in 1987. It was recovered in Antarctica (-72.0, 26.0). It has a mass of 132.11 grams.
Asuka 87346 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.
Asuka 87346’s official classification is CO3.3. The “CO3.3” classification applies to a carbonaceous chondrite within the CO group, specifically a type 3 meteorite, indicating a particular degree of metamorphism within this class. These meteorites are known for their small chondrules, minimal refractory inclusions, and a composition that showcases a balance between abundant chondrules and a mineral assemblage that is not fully equilibrated, often featuring low-calcium pyroxene grains with unique twinning patterns.
The Asuka 87346 meteorite is a “find” 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.
