This paper describes briefly the major developments of the research on salt tectonics in oil-gas-bearing basins in recent years.These developments include mainly the geological modeling of salt tectonics, three-dimensional visualization, physical and numerical modeling, balanced cross-section and restoration, and deformation mechanisms of salt tectonics.Salt tectonics, distributed widespread in oil-gas rich areas such as the Persian Gulf Basin, the North Sea, Gulf of Mexico, Caspian Basin, North Europe and African passive margins, are closely related to hydrocarbon accumulations.Polyphase salt layers and a variety of salt tectonics are developed in the Tarim, Bohai Bay, Jianghan and Sichuan basins.Research work must focus on salt and salt-related deformation assemblages, 3-D geological modeling and 3-D visualization, origin and geodynamic evolution of salt tectonics in China.Regional salt caps are the key to the preservation of oil-gas pools in Tarim, Bohai Bay, Sichuan basins and marine carbonate rocks in south China.It is very important to understand the processes of tectonic evolution, structural styles and hydrocarbon accumulation by studying salt tectonics.
