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. There are two types of large igneous provinces in the world: one is mainly mafic LIP, and the other is felsic LIP. The two types of large igneous provinces in China are respectively represented by the Permian Emeishan basalt and the eastern China large-scale magmatic activity. Both were possibly related to the plume activities; nevertheless, in the mafic large igneous province, massive basalt eruption took place together with partial melting when the plume migrated upward to the bottom of the lithosphere, whereas in the felsic igneous province, the magmatic formation of felsic composition could directly bake and heat the lower crust when the plume reached the crustal bottom. Researchers generally consider that the large-scale magmatic activity during Mesozoic was related to westward subduction and asthenosphere uplift of Pacific plate. 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.
