| 摘 要： | 利用断裂活动过程中留下的各种地质标记研究断裂发育史是比较困难的 ,已有的研究方法主要可归纳出七种 ,都存在局限性。岩层离距图法是以地震剖面为基础 ,将穿过断裂的各剖面上的标志层投影到沿断裂走向的铅垂面上 ,得到多组标志层的垂向断距数据 ,然后用下部各标志层的断距减去最上部标志层的断距 ,并作多轮次计算 ,直到最后的断距差近似为零或仅剩一个非零标志层。每一轮次计算代表一个活动期次 ,如果出现负值 ,则表示有构造反转。对松辽盆地敖古拉断裂作了实例计算 ,结果为该断裂发育经历了三个正断活动期和一个逆断活动期 ,与盆地区域性活动有些差别。岩层离距图法比起其他已有方法 ,可靠程度大大提高

| Abstract: | On the basis of comparing other different methods for researching the development history of fractures, the fault distance drawing method by regional seismic data that is brought forward here is much more precise and reliable than the profiling method. To describe the theory and application of this method, Aogula Fracture, the Jurassic successive active rift, in Songliao Basin is illustrated as an example. The calculated result indicates that the fracture has ever experienced the Jurassic, Cretaceous Quantou and Mingshui normal faultings and the Tertiary Yi'an reverse faulting, which were not consistent well with the regional tectonic environments in the basin. |
