Allan Hills 88020 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 88020’s official classification is H3.5. An “H3.5” meteorite is a type of ordinary chondrite from the H group with petrologic type 3 characteristics. Ordinary chondrites are a major class of meteorites known for their abundant chondrules, and the H group within them is distinguished by its high iron content and smaller chondrules. Petrologic type 3 indicates that the meteorite has low degrees of alteration and unequilibrated mineral assemblages, with specific features like monoclinic low-Ca pyroxene grains and polysynthetic twinning.
The Allan Hills 88020 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.
