The author believes that it is very difficult to explain large-scale magmatism in eastern China during Mesozoic with the hypothesis of Pacific plate subduction, and that the magmatism might be equivalent to several felsic large igneous provinces in different periods, probably related to the Mesozoic super mantle plume activity in East Asia. In this paper the author believes that the large-scale magmatic activity was probably related to the plume from the lower mantle. The large igneous province has rich mineral resources: resources such as copper, nickel, chromium, platinum and palladium might be related to the mafic igneous province, whereas resources like gold, copper, tungsten, tin, molybdenum, bismuth, antimony and uranium might be related to the felsic large igneous province.
