CK Group
The meteorites of this group are named for Karoonda, a meteorite that
fell in Australia in 1930. There are only about 20 different CK members
known if we exclude all the pairings that have been found so far in the
hot deserts of Africa and on the blue-ice fields of Antarctica. Initially,
those meteorites were regarded as members of the CV group and were
designated as CV4-5. However, more recently, they have been given their
own group since they differ in some respect from all the other
carbonaceous chondrites.
The chondrites of the CK group belong to the petrologic types 3 - 6,
although most of them have been classified as CK4. They are of a dark-grey
or black appearance due to a high percentage of magnetite that is
dispersed in a matrix of dark silicates, consisting of iron-rich olivine
and pyroxene.
