Abstract: The China continental lithosphere is composed of over 37 small blocks, the formation periods of which are different. Those blocks migrated from Proterozoic to Cenozoic, and dispersed mainly during Paleozoic in Tethys Ocean. They converged gradually during Mesozoic and Cenozoic, and at last formed recent China continental lithosphere. By being influenced on migration of surrounding plates, the normal continental lithosphere formed in middle and northwestern China, the thinner lithosphere with the type of continental crust and oceanic lithosphere mantle occurred since Jurassic, and there is the lithosphere with thicker crust type at southwest China, i.e., Tibet and Qinhai areas. There are many detachments in China continental lithosphere. Besides detachment of lithosphere bottom, the detachments are occurred at Moho discontinuity and middle crust, thus the inner structure of lithosphere is more complex, which caused the stronger deformation, magmatism and many metallic ores. Due to the particularity of China continental lithosphere, the characteristics research of lithosphere evolution is provided with the very important value for theory and practical, and also can develop the plate tectonic theory.
