l’盆地的地球動力學分類 盆地形成機制和類型是一個爭議較多的主題,可以從系統論角度進行定性、定時和定量3方面來分析:定性就是從全球動力學角度和活動論觀點來確定盆地形成機制和性質;定時就是從板塊構造運動學角度和階段論觀點來研究盆地演化序列和構造轉化或構造反轉特征
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.
