应用多种地球物理方法研究结果 ,经过综合对比分析 ,编制了中朝地台东北缘及其邻区岩石层厚度图 ,探讨了软流圈顶部埋深分布特征的大地构造意义及地球动力学特征。指出软流圈顶部埋深与中新生代以来构造活动和现代断裂活动及地震活动具有较为密切的关系。海拉尔盆地、渤海湾 -下辽河盆地、松辽盆地等是上地幔软流圈普遍上隆地带 ,也是现今地震活动和地表下沉地区 ,认为它们与上地幔软流圈上隆具有明显的联系。
Using a variety of geophysical methods to study the results, the thickness maps of the lithosphere in the northeastern margin of China-DPRK platform and their adjacent areas have been compiled through comprehensive comparative analysis. The significance of geotectonic and geodynamic characteristics of the distribution characteristics of the top of the asthenosphere is discussed . It is pointed out that the top of the asthenosphere has a close relationship with tectonic activity, modern fault activity and seismic activity since Mesozoic and Cenozoic. The Hailaer Basin, the Bohai Bay-Lower Liaohe Basin, and the Songliao Basin are all common uplifts in the upper mantle asthenosphere and are also the present-day seismic activity and surface subsidence areas. They are clearly associated with asthenosphere uplift in the upper mantle.
