CK4/5 Meteorite Classification

Class Description

The CK4/5 meteorite classification refers to a group of meteorites that are part of the CK (Karoonda) type within the carbonaceous chondrites, known for their composition similar to the sun’s and distinctive oxygen isotope properties. These meteorites straddle the boundary between type 4 and type 5, indicating they have undergone significant but not full metamorphism, resulting in a mix of characteristics like uniform mineral compositions and the beginnings of secondary mineral growth.
