中国中、新生代含油气盆地成因类型、构造体系及地球动力学模式

GENETIC TYPES,TECTONIC SYSTEMS AND GEODYNAMIC MODELS OF MESOZOIC AND CENOZOIC OIL AND GAS BEARING BASINS IN CHINA

讨论了中国中、新生代含油气盆地的成因类型、构造体系和地球动力学模式：（１）按照地球动力学背景，将中国中、新生代盆地划分成伸展、缩短挠曲和走滑３种成因类型；（２）提出了含油气盆地构造体系的概念，并按照盆地成因类型、板块构造背景和构造演化讨论了中、新生代含油气盆地构造体系的分布；（３）根据构造几何学、运动学和动力学、火山岩岩石地球化学、基底和岩石圈结构以及地温场等特征，建立了有关大陆内伸展盆地和前陆盆地的地球动力学模式。

The genetic types, tectonic systems and geodynamic models of Mesozoic and Cenozoic oil and gas bearing basins in China are studied:(1)based on the geodynamic setting, the Mesozoic and Cenozoic basins in China are classified as three types of extensional, shortening flexural and strike slip basins;(2)the concept of basin tectonic system is suggested, and based on the genetic types, plate tectonic setting, tectonic evolution and the occurrence of the basin tectonic systems of Mesozoic and Cenozoic basins in China are outlined;(3)according to the structural characteristics of Mesozoic and Cenozoic basins in China, such as structural geometry kinematics and dynamics, petrological and geochemical characteristics of volcanic rocks, basement block structure, lithosphere character and geothermal background,the geodynamic models of extensional and foreland basin formation are established.
