| 摘 要： | 岩石圈流变性取决于岩石圈的地热状态、物质组成和结构，并量化为岩石圈总强度。沉积盆地的沉降和抬升是地球最上层流变带形变的响应，岩石圈板块对构造应力的响应在很大程度上取决于岩石圈流变性在横向和纵向上的不均一性。辽西、辽北、松辽盆地区岩石圈流变性存在明显差异，因而岩石圈总强度明显不同，在晚中生代伸展过程中，变形方式、变形幅度不同，分别形成了断陷盆地、多断少坳型盆地和断坳型盆地。

| Abstract: | The rheology of the lithosphere which determines the overall strength of the lithosphere is controlled by geothermal, composition and structure of the lithosphere. The response of lithosphere to tectonic forces is controlled by the spatial variation of strength of rheology of the lithosphere. Sedimentary basins are expression of rheological deformation process on a lithospheric scale. With great differences in lithospheric rheology and strength, there developed fault basin, more fault and less depression basin and fault depression basin in west Liaoning, north Liaoning and Songliao basin area respectively. |
