Kimberlites in China and Their Major Components: A Discussion On the Physico-Chemical Properties of the Upper Mantle

Kimberlites have been found on the North China platform and Yangtze platform, providing a source of diamond in China, and yielding samples of rocks and minerals for research into the physico-chemical properties of the upper mantle beneath the continental region of China. The purpose of this paper is to discuss the geologic background of kimberlites in China, the mineral components, textures and age of the kimberlites, the deep ultramafic xenoliths, and to discuss models of magma ascent and physico-chemical properties of the upper mantle.
