针对色力布亚断裂以往研究中存在的问题,从构造较简单的北部入手,对断层的断期及活动性作了分析,得出其活动期始于中新世初、消亡于上新世、中新世末是断裂最活跃时期的结论,并证明二叠纪末色力布亚断裂无断开形迹。文中还介绍了采用画试商剖面求取始断期的方法,其效果是好的。 In view of the existing problems in the study of the Sericite fault, from the relatively simple northern part, the fault period and activity of the fault were analyzed. It is concluded that the active period of the fault began in the early Miocene and died in the Pliocene , And the end of Miocene is the conclusion of the most active period of fracture. It is also proved that there is no disconnection of Permian Late Permian Libya fault. The paper also introduced the use of painting quotient profile cut-off period of the method, the effect is good.
