On the basis of the existing researches of basin worldwide and basin analysis, this paper establishs the new principle of basin classification, discusses the dynamics types of basin evolution, and further expounds the geodynamics mechanism of basin evolution and expansion from three aspects of the lithosphere plate, deep lithosphere and lithosphere supergene action. The new classification principle is ensured to be systematic, scientific, and practical. According to our research, the basin classification should first consider the geodynamic environment of basin formation and evolution, including the lithosphere plate and deep effect environment and lithosphere supergene action, and then take all kinds of geologic function and the dynamic process of basin formation and evolution, such as tectonic setting(extending, compressing and shear process), thermal effect and gravity division into account for main classification, finally, the different nature of the basin basement and crustal types, as continental crust, oceanic crust or transitional region basin, as well as the history of basin sedimentary filling and tectonic palaeogeography, evolution of the small class segment such as marine sedimentary basin, continental basin, and transitional facies basin should be considered for the further sub-classification. In the process of basin formation and evolution, the basic dynamic type of basin includes: The prototype basin evolution under a single tectonic or thermal system, the prototype basin evolution under a single gravitation system, the superimposed basin evolution under multiple thermal tectonic systems and the residual basin evolution under multiple tectonic thermal systems. In a single tectonic or thermal system, from lithosphere plate and mantle and crust action, prototype basin dynamic types have extension basin(intracontinental extension basin, continental extension basin, oceanic extension basin and back-arc extension basin), the flexural basin(back-arc flexural basin, peripheral torsion flexural basin and intracontinental flexural basin), strike-slip basin(strike-slip extending basin and strike-slip compressing basin) and craton basin(craton retreating basin, craton expanding basin and craton migrating basin).The superimposed basins under multiple tectonic thermal systems include the superimposed basin and composite basin, while the residual basins under multiple tectonic thermal systems includes the residual basin caused by extend uplift under local subsidence, fold-thrust uplift, underthrust to part impaction uplift, peripheral uplift. The earth dynamics mechanism of basin formation and evolution include the lithospheric plate mechanism, lithospheric deep mechanism and supergene action mechanism of the lithosphere. Lithospheric plate mechanism includes a plate extending, compressing and shearing action while lithospheric deep mechanism include the effect of asthenosphere and super mantle plume in the lithosphere, especially the crust-mantle. Lithospheric supergene action mechanism is supposed to be most important, including effect of gravity of basin, atmosphere, ocean and biology. This study could provide the important theoretical foundation for the evolution of the lithosphere, crust-mantle action, and the earth dynamics process and accumulation metallogenic mechanism, and could be valuable for for the mineral resources, energy resources and water resources exploration and development of sedimentary basin, and disaster prevention and environmental protection as well.
