Opaque Assemblages in CK and CV Carbonaceous Chondrites

Introduction: CK carbonaceous chondrites are the only group of carbonaceous chondrites that exhibit thermal metamorphism. As a result, CKs display features of metamorphism such as silicate darkening, recrystallization and shock veins. Calcium Aluminum Inclusions and Fe-Ni metal are rare.

Spectral reflectance properties of carbonaceous chondrites: 7. CK chondrites

The reflectance spectra of 15 CK chondrites have been measured as part of an ongoing study of carbonaceous chondrite reflectance spectra. The available sample suite includes multiple grain sizes and samples with petrologic grades varying from CK4 to CK6. CK reflectance spectra are all characterized by an olivineassociated absorption band in the 1.05 lm region. Compared to pure olivine, CK spect...
