Allan Hills A78230’s official classification is Acapulcoite. The “Acapulcoite” classification refers to a meteorite that is part of the primitive achondrite group, indicating it has undergone heating and partial melting, maintaining a composition close to its original chondritic state. These meteorites, linked to the acapulcoite-lodranite family, are equigranular with fine grains, and sometimes include rare, original chondrules, displaying a unique mineral composition that is somewhat different from ordinary chondrites.
The Allan Hills A78230 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.
