摘要


     libri" size="3">Basin formation and its structure record basin tectonic evolution, which reflects the different periods of tectonic settings. As the development of the exploration in oil and gas, lots of seismic sections have been accumulated. This provides a large number of basic data for comparison of the characteristics of basins. Materials from hundreds of important sedimentary basins were collected to study the basin tectonic evolution and evolutionary background systematically based on the global structure theory.

The evolution and structure of basin groups in Asia were controlled by the ancient Asian continent, Tethys, and west Pacific tectonic zone. By the cffection of plate boundary, different basin groups in the same continent have close relationship in structure, sedimentation, and tectonic events. Basins containing the richest oil and gas are mainly located within the plate, away from the extrusion plate boundary. These basins generally have a huge cumulative deposition thickness, weak interior faulting, and stable sedimentary and tectonic subsidence.
