摘要
作为对中国东部陆缘地带大型盆地区及邻区地质—地球物理综合研究的部分结果 ,本文的基本认识 :(1)穿过松辽盆地的 1孙吴—双辽断裂可能是东倾的低角度壳内断裂 ;(2 )松辽盆地和渤海湾盆地可能属于“混合型裂谷盆地” ;(3)东海盆地台北坳陷处在多期次张性应力场环境中 ,使在其西部附近产生张性正断层系 ;(4)欧亚大陆东部新生代区域构造运动总体处于右旋走滑拉张环境 ,其动力因素包括板块运动和地幔物质运动 ;(5 )研究区莫霍面具有较为复杂的变化 ;(6 )复合尺度研究方法是地质—地球物理综合分析的必要手段 .
The comprehensive geolgy Geophysics analysis of large basins and their surrounding areas in eartern China achieved many maluable results. Some of them are published here. They are as follous: (1) Sunwu Shuangliao fracture, which crosses Songliao basin, may be the intracrustal fracture that inclines eastward and has low angle; (2) Songliao basin and Pohaiwan basin may be the 'mixed rift basin'; (3) Because Taipei sag of East China Sea basin stands in the many stage tensile stress field, tensile normal fault system are generated near the west of Taipei sag; (4) The stress field of Neozoic tectogenesis stands in the dextrorotatory slippery tensile situation in the east of Eurasia. The geodynamical factors include plate movement and the motion of matter in mantle; (5) Moho has complex change in research zone; (6) Composite scale method is an essential method for the comprehensive analysis of geology geophysics.
