Allan Hills 84028 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.
Allan Hills 84028’s official classification is CV3. The “CV3” classification denotes a carbonaceous chondrite from the CV group, specifically a petrologic type 3 meteorite, known for its large chondrules, many with igneous rims, and significant refractory inclusions. These meteorites, characterized by a substantial matrix and divided into oxidized and reduced subgroups, feature a rich abundance of chondrules and a mineral composition that indicates low water alteration and a lack of equilibrium in its mineral assemblages.
The Allan Hills 84028 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.
