In this paper, three types of igneous petrotectonic assemblage s in t hree tec tonic settings, and their corresponding lithosphere—asthenosphere systems are p ut out. Disc uss ion emphatically on the constraints of the magmatism and deep crust—mantle proc e sses to the metallogenesis, and briefly on the environmental effect has been made. The significance of study on the evolution trend of the lithosphere-a sthenosphere system for the prediction of the China continent in the future is a lso discussed.
