More Details About the Asuka 87031 Meteorite
The Asuka 87031 meteorite was discovered in 1987. It was recovered in Antarctica (-72.0, 26.0). It has a mass of 15.21 grams.
Asuka 87031 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 87031’s official classification is Ureilite. A “Ureilite” is a type of stony meteorite that belongs to the ureilite group. These meteorites are unique because they are ultramafic and contain interstitial carbon in the form of graphite or diamond. Most ureilites consist of olivine and pigeonite, but some may have different pyroxenes, and a small portion are polymict breccias, which means they contain additional feldspathic material along with typical ureilitic components.
The Asuka 87031 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.
