Abstract: Studies on tectonisms in oil/gas-bearing regions in China, ranging from views on geosyncline and platform theory to those on the theory of Plate Tectonism, were applied to researches on the textures, movements and evolutions of the lithosphere, which consists of the crust and the upper mantle. The mechanism of deep crustal movements in neo-global stage (since Indosin-ian Period) was clarified, and the impact of origins and evolution of Meso-zoic to Cenozoic rift basins and depressions, and structures on the generation, transportation, accumulation, preservation and mineralization of hydrocarbon resources were also studied. These studies contributed a lot to the discoveries of numerous oil/gas fields, both onshore and offshore.
