摘要
辽河盆地新生代火山岩的分布规律和岩石学特征表明：辽河盆地新生代的构造环境为大陆裂谷。地壳深部资料显示出辽河地区存在上地幔隆起，它控制了浅部构造的发育。而辽河盆地新生代断裂构造组合，反演出辽河盆地新生代４期的构造应力作用方式。为此，笔者将造山和成盆作用纳入统一的动力学机制，提出了辽河盆地新生代构造演化的动力学模式。
The petrology of the Cenozoic volcanic rocks and their distribution in the Liaohe basin indicate a continental rift environment;The uparching of the upper mantle revealed by geophysical data has controlled the development of the structures on the surface.Four periods of tectonic stresses were determined from the combination pattern of the Cenozoic fractures.Finally,the authors propose a model of the formation and evolution of the Liaohe basin,combining orogeny with basin formation.
