CONTINENTAL RIFT VALLEY SYSTEM AND SEISMIC ACTIVITIES IN NORTHEAST CHINA |
| |
| Abstract: | The Northeast China continent is restricted by the regional stress field, and within it, are developed the NE trending Xialiaohe and Songliao rift valleys. The continental basement is filled with the loose clastic sediments of continental fades, from 1000 up to 5000m in thickness. From the rifts border were ejected lava of olivine basalt and hot water springs, as a result, formed the rings as the earthquake-control zones. The mechanism of the rift valley formation could be viewed as a reflection |
