Abstract
Four CB type carbonaceous chondrites, Gujba, Bencubbin, NWA 4025 and NWA 1814 were investigated to describe high-pressure polymorphs formed in their melting textures. Many kinds of high-pressure polymorphs were identified from all samples, implying that the parent-body of CB type carbonaceous chondrite was heavily shocked.
