CK Meteorite Classification

Class Description

The CK classification refers to a meteorite that is a member of the Karoonda (CK) group of carbonaceous chondrites, which are known for their composition closely resembling the Sun’s, especially in terms of magnesium to silicon ratios, and oxygen isotopic values that differ from those found on Earth. While it belongs to this distinct group characterized by a high proportion of fine-grained matrix, chondrules without igneous rims, and a notable level of oxidation, the specific petrologic type of this meteorite has not yet been determined, indicating that its exact metamorphic stage is still to be classified.
