Abstract: Following the Chinese-subduction (C-subduction for short) viewpoint proposed by Prof. Luo Zhi-li in 1984, it resounded inten-sively in China's geology circles. In the past near 20 years, this viewpoint has been verified by more and more geological phenomenon, and accepted by more and more people. According to the viewpoint, suggestions are made that C-subduction belt is between old folded mountains and inland basin marginal depressions in geotectonic location; in the early stage, it belongs to normal faults followed by reverse faults in the late stage, becoming active sliding subduction faults along mountains in basinal depression margin; it is in good oil-generating conditions: in the early stage of shaping thrust belt tend to be thicker marine and continental-marine interaction deposits,in the late stage form foredeep basins, in Meso-Cenozoic appear favorable oil-generating environment of lake facies; Qinghai-Tibet highland growing up is related to the C- subduction activity along Longmenshan mountain besides associating with collision between India Plate and Eurasia Plate in Cenozoic; C-subduction occurs not only in western-central China, but also in easterm China. Hence, this C-subduction viewpoint enriches and perfects the models about forming Meso-Cenozoic orogenic zone in plate theory,which definitely is an innovation on geotectonic theory made by Chinese geology researchers.
