阿尔金断裂与周缘新生代盆地关系
The relation between the Altyn Tagh fault and the Cenozonic basin

摘要: 通过野外填图工作,在阿尔金断裂附近填绘出一系列的新生代地层,对这些地层目前的展布与阿尔金活动断裂的关系分析认为,始新世以来阿尔金断裂对沉积盆地表现出明显的控制作用,表现为明显的左行走滑,并兼具向北西方向掀斜的逆冲活动。乌尊硝尔盆地(索尔库里盆地西部)中的主体沉积是第四系。盆地的东南边界是阿尔金南缘主断裂;盆地西南缘,第四系沉积受东西向北倾正断层控制;盆地北缘为近东西向北倾右行逆冲脆性断裂。盆地的西部边缘超覆在基岩之上,不受断裂控制。Abstract: We mapped some Cenozonic strata in Suwushenjie, neighbouring the Altyn Tagh. According to the relation of the distribution of these strata to the Altyn Tagh fault, we believe that the Altyn Tagh did not slip in the early-mid Jurassic and the Jurassic was not controlled by the Altyn Tagh fault; the Altyn Tagh fault began to controlled sedimentation basin since Eocene.It is indicated that the Altyn Tagh fault had slipped in that time. Quaternary deposit is the main sedimentation of the Wuzunxiaoer(the west part of Xorkol)basin. The southea stedge of the basin is controlled by the main Altyn Tagh;on southwest edge,the westeast strike and dip north normal fault confined Quaternary deposit;the north part of the basin is westeast strike and dip north fault which is a dextral strike slip and brittle fault. The west edge of the basin overlapped on bed rock,there is not any sub stantive relation with the Altyn Tagh fault.
