More Details About the Acfer 085 Meteorite
The Acfer 085 meteorite was discovered in 1990. It was recovered in Foggaret Ezzaouia, d’In Salah District, In Salah, Algeria (27.58333, 3.95). It has a mass of 293 grams.
Acfer 085 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.
Acfer 085’s official classification is H5. The “H5” classification indicates a high-iron ordinary chondrite from the H group, characterized by its relatively small chondrules and siderophile elements, with oxygen isotope ratios nearing Earth’s values. This type 5 meteorite has undergone significant metamorphism, leading to a uniform composition of minerals like olivine and pyroxene, growth of secondary minerals, and less distinct chondrule features.
The Acfer 085 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.
