Systematic study on the structural styles recording in the Qingbaikou system and the Paleoproterozoic basal in the western segment of Quruqtagh indicates,that their deformation assemblages characteristics are overall reflect the structural mechanism of bedding sliding from NW to SE.The age of the rhyolite in the top of the Beisainartag Formation which involved in the deformation and the age of the rhyolite in the base of Nanhuan system which didn’t involved in the deformation indicates that the deformation time interval of this decollement structure movement are (841.5±2.3)Ma to (736 ±3.1)Ma.It is indicated that the tectonic movement might be the record of the early crustal deformation in the northeastern tarim edge,in the breaking up period of the Rodinia supercontinent.%系统分析记录库鲁克塔格地块西段青白口系及古元古代基底顶部构造样式，认为其变形组合特征总体反映了NW向顺层拆离滑脱构造机制。青白口系顶部卷入变形流纹岩及南华系底部未变形流纹岩测年数据显示，本次滑脱构造变形时代限定在（841.0±1.4）Ma~（738.9±5.4）Ma，表明构造变形可能对应Rodinia超大陆裂解事件，为此次构造事件塔里木东北缘地壳变形记录。
