The relation between the Altyn Tagh fault and the Cenozonic basin

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.
