| 摘 要： | 应用平衡剖面法计算了济阳拗陷新生代不同时期的第一主张应力方向：Ek-Es4时期，盆地主应力方向为NNE向；Es3+2时期为NNW向；Es1-Ed时期为NWW向；新近纪和第四纪为近N-S向.区域第一主应力方向与盆地断裂活动性、构造变革面、盆地沉降史均具有较好的吻合性.济阳拗陷是以断陷为主，叠加走滑的复合型盆地，经历了裂陷+走滑-走滑-裂陷-拗陷4个阶段.

| Abstract: | The balanced section method is adopted to calculate the directions of the first principal tensile stress during Cenozoic period in Jiyang depression.The result shows that the principal stress direction is NNE during Ek-Es4,NNW during Es3+2,NWW during Es1-Ed,and N-S in Neogene and Quaternary.The first principal stress directions are closely correlated with the fault activity,tectonic interface changing and subsidence history of the basin.The Jiyang depression is a composite basin which is dominated by rift and superimposed with strike slip.The basin has experienced four stages,namely,rift plus strike slip,strike slip,rift,and depression. |
