In this regard , the study of kimberlite has the potential to provide information about the composition of the deep mantle and about melting processes occurring at or near the interface between the cratonic continental lithosphere and the underlying convecting asthenospheric mantle .
The study of kimberlite has the potential to provide information about the composition of the lower mantle . Little is known about melting processes at or near the interface between the cratonic continental lithosphere and the underlying convecting asthenospheric mantle .
