DYNAMIC CLASSIFICATION OF SEDIMENTARY BASINS AND THEIR STRUCTURAL STYLES
Liu Hefu (China University of Geosciences;Beijing 100083)
Sedimentary basins can be classified in terms of (1) geometry, (2) kinematics, (3) dynamics, and (4) chronology. In dynamic terms, the basins fall into three main categories: (1) extensional basins, (2) compressional basins and (3) strike-slip basins. Special geometric features of these basins can be identified in different evolution stages in terms of plate movement. Their relevant structural styles are extensional, compressional and strike-slip. Structural analyses provide both theoretical and technical means for oil and gas exploration. Classification of basins can be made on the basis of the theories of global dynamic system and plate tectonics. Structural styles comparison can provide various geological models for the prediction of trap types and for the interpretation of seismic reflection profiles.
【Keyword】：extensional basin, compressional basin, strike-slip basin, structural styles, geodynamics.
