More Details About the Frontier Mountain 90212 Meteorite
The Frontier Mountain 90212 meteorite was discovered in 1990. It was recovered in Antarctica (-72.95551, 160.43643). It has a mass of 3.7 grams.
Frontier Mountain 90212 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 90212’s official classification is L6/7. The L6/7 meteorite classification refers to a group of meteorites that belong to the L category, known for their lower iron content. These meteorites are in an advanced stage of metamorphism, straddling the boundary between type 6 and type 7, which means they have undergone extensive geological changes that significantly alter their mineral composition and structure, leading to highly homogenized minerals and a loss of original features like chondrules.
The Frontier Mountain 90212 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.
