The present China is located in the southeastern part of the Asian continent and the middle segment of the west Pacific active belt. Viewed from the major lithospheric plate map of the globe, it lies in the southeast of the Eurasian plate, with the Pacific and the Philippine Sea plates on the east, and the Indian plate on the south. In the geological history, the main part of China marked by the SinoKorean, Yangtze and Tarim cratons was situated in the interchange domain between Gondwana and Siberia: in Paleozoic time, it was located in the south of the PaleoAsian Ocean, belonging to a structurally complicated continental margin of Gondwana; and in Mesozoic time, located on the north of the Tethys, being a part of Laurasia. The tectonic evolution of China in the Phanerozoic has been controlled successively by the PaleoAsian Ocean, TethysPaleoPacific and PacificIndian Ocean dynamic systems, forming the PaleoAsian Ocean, Tethys and Pacific tectonic domains. Either the PaleoAsian Ocean or the Tethys was not a simple ocean basin, but a structurally complex ocean system made up of seafloor rift zones (small oceanic basins) and numerous microcontinents. As a result of the superimposition of the MesoCenozoic Pacific and Tethys tectonic domains on the Paleozoic PaleoAsian Ocean tectonic domain, the tectonic map of China presents a mosaic structure on plane and an overpass architecture in threedimensional space. Therefore, China is the most structurally complex region not only in Asia, but also in the world. Overlapping and compounding of the dynamic systems in different periods have made the polycyclic tectonismmagmatism and mineralization dominate over the geology of China. Thus, the orogenic belts, metallogenic belts and the large petroliferous basins of China are mostly polycyclically superimposed.
