Graves Nunataks 98019’s official classification is Eucrite-br. The “Eucrite-br” classification indicates a brecciated type of achondrite from the eucrite group, characterized by a composition without chondrules and an origin from a differentiated celestial body. These meteorites, primarily composed of Fe-rich pyroxene and Na-poor plagioclase, are a common type of basaltic achondrite, sharing geochemical properties with diogenites and howardites within the HED meteorite group, and possibly associated with asteroid 4 Vesta.
The Graves Nunataks 98019 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.
