Abstract:
Based on the results of multiple geophysical research methods,the lithosphere thicknessisolines of the northeastern margin of Sino-Korean platform and its neighboring area havebeen compiled and the geotectonic significance and the geodynamic characteristics of depthdistribution of asthenosphere roof have been also discussed.The authors proposed that closerrelation exists between the depth of asthenosphere roof and the tectonic activity as well as themodern faulting and seismic activity from Meso-Cenozoic Era till now.The upper mantleasthenosphere is generally uplift in Hailar basin,Bohal Bay-Xia Liaohe basin andSonghuajiang-Liaohe basin.Meanwhile,there exists modern seismic activity and groundsubsidence in this area.It is result from the uplift of upper mantle asthenosphere.
Key words:  Upper mantle asthenosphere  Lithosphere  Gradient belt  Dynamical parameter
