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.
