沈阳地区地壳稳定性的讨论

A DISCUSSION OF STABILITY OF THE CRUST IN THE SHENYANG AREA, LIAONING

沈阳地区位于中朝准地台Ⅲ级构造单元的下辽河断陷与铁岭—靖宇台拱的衔接地带,区内地质构造较复杂。北东向、北北东向和北西向三组主要断裂,无论其形成时代早晚均具多期活动特点,且存新构造运动中部发生了不同程度的继承性活动,从而影响了沈阳地区地壳稳定程度。对此在今后城市发展和规划时,应给予足够重视。

Shenyang area is located bonding zone between the lower Liao Rever Basin and Tieling-Jingyu Swell in the Sino-Korean quasi-platform. The geological structure in the area is very complicated. Three sets of faults in the direction of northeast, north-northeast and northwest all show features with multiperiod activity whether their formation age no matter early or late of is early or late. They display inherit mobility in varying degrees in new tectonic movement, and have influence on the stability of thecrust of Shenyang area. City planing and developing must pay sufficiently attention, to the fact.
