Queen Alexandra Range 99679’s official classification is CK4. The “CK4” classification identifies a carbonaceous chondrite from the Karoonda (CK) group, characterized by a high content of fine-grained matrix, chondrules without igneous rims, and a notable degree of oxidation. As a type 4 meteorite, it has undergone metamorphism leading to uniform olivine compositions, recrystallized matrix, and an absence of primary igneous chondrule glass.
The Queen Alexandra Range 99679 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.
