Continent of China & adjacent areas was pieced together by the orogenic belts in different periods, and consisted of the five type lithospheres (Qiu et al., 2006, 2014). The area between the different type lithospheres was defined the lithospheric discontinuity zones (Kutina, 1995), which show differences on the many aspects such as the crust-mantle structure, rock composition, heat flow and thickness of the crust and the subcontinental lithospheric mantle, and should be have the close relationship with the metallogenesis. five types lithospheres are recognized in east China, including Eerduosi and Yangzi cratonic lithosphere, Yanshanian orogenic-type lithospheres represented by the Da Hinggan and Yanshan-Taihang mountains and central segment of the Nanling Mountains remain, rifttype lithospheres represented by the Songliao plain, North China plain and sea areas off Fujian and Guangdong, oceanic crust-type lithospheres represented by the Central sea basin of the South China Sea, and the island arc-type lithosphere represented by that of Taiwan. Masses of the lithospheric discontinuity zones in east China means having the important factors would cause the strongest and more active tectonic-magmaticmetallogenic events.
