More Details About the Elephant Moraine 90006 Meteorite
The Elephant Moraine 90006 meteorite was discovered in 1990. It was recovered in Antarctica (-76.28523, 156.44781). It has a mass of 23.9 grams.
Elephant Moraine 90006 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.
Elephant Moraine 90006’s official classification is CK5. A “CK5” meteorite is a type of carbonaceous chondrite from the CK group that is both anomalous and of petrologic type 5. Carbonaceous chondrites are a major class of meteorites with specific chemical characteristics, and CK chondrites have unique properties such as abundant fine-grained matrix, distinctive chondrules, and a high degree of oxidation. A CK5 meteorite has been metamorphosed to petrologic type 5, which means it has undergone changes that homogenized its mineral composition, converted low-Ca pyroxene to orthopyroxene, and caused the growth of secondary minerals while blurring chondrule outlines.
The Elephant Moraine 90006 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.
