Lamproite and kimberlite of the Sayany area: Composition, sources, and diamond potential.

The article presents a study on the composition, sources, and diamond potential of lamproite and kimberlite found in the Eastern Sayany area. It states that the Eastern Sayany area is a foreboding region for the discovery of original diamond deposits of various genetic types. It notes that several stages of lamproite and kimberlite intrusion are being identified within the Eastern Sayany area including the Mesoproterozoic, Neoproterozoic, and Middle Paleozoic. Moreover, the study speculates on the primary estimations of isotope geochemical specifics of deep sources of lamproitic, kimberlitic, and alkaline ultrabasic magmatism of the Siberian Platform region in Russia.
