在塔里木盆地西南地区，“外来地质体”的并入以及后续板内块体间的敛合作用，引起了一系列形变事件，使原来沉积的中新生界前陆层序发生形变，沿西昆仑造山带东侧山麓地带发育前陆褶皱和逆冲带。在英吉沙(克孜勒)地区，受喜山期“陆内榨挤”(朱夏，1991)构造作用，以及由此伴生大型“共轭”剪切(走滑)作用影响，分别出现“薄皮构造”和“飞来峰”构造样式。影响形变的主要因素是地层强度和底部滑脱面横向延伸范围。西昆仑造山带东侧山麓地带，是一个重要的油气资源区。参照邻区的柯克亚地区、乌恰地区油气(藏)发现成果，推断这一地带可能形成油气藏，油气充注期在时代上与最晚强烈逆冲活动期(中新世以来)大致对应。

Structural Geology Features in Yingjisha Area of Southwest Talimu Basin

??A series of structural deformations had been formed as the overgrowth of strange geological block and intraplate squeezing activity in the southwest area of Talimu Basin,Which made the foreland sequence of Mz-Kz deformed.The foreland folding thrust belt and the foothill belt in the east of West Kunlun orogen are developed.In Yingjisha area,affected by the actions of intraplate squeezing and X conjugate shear,the structural patterns of thin skinned structure and nappe outlier had been formed.The deformations were controlled by formation strength and glide plane.The foothill belt is an important hydrocarbon resource area.Comparing with the exploration results in the adjacent regions as Kekeya and Wuqia,an oil gas reservoir filled by the source rock buried depth with the thrust nappe action could be in the area.
