Frontier Mountain 90200 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.
Frontier Mountain 90200’s official classification is Ureilite-pmict. The “Ureilite-pmict” classification refers to a specific type of meteorite from the ureilite group, which are unique achondrites, meaning they are stony meteorites without chondrules and come from a body that has undergone differentiation. This particular ureilite is identified as a polymict breccia, indicating it is a composite of various rock fragments, including a mix of minerals like olivine and pigeonite, and occasionally contains carbon in the form of graphite or diamond.
The Frontier Mountain 90200 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.
