摘　　要：通过对新疆吉木萨尔大龙口背斜核部露头剖面的野外观察、实地测量和特征描述,分析研究了其构造发育特征和演化模式。认为大龙口背斜核部露头的构造属于"褶皱相关断层"范畴,岩层能干性对构造变形具有重要影响,最为典型的是发育了"褶翼楔入组"、"类冲起"和"分离反向褶曲"3种特殊的构造样式。This study conducted field observation, field measurements and feature description of the outcropped profile at the Dalongk- ou anticline core in Jimsar County of Xinjiang, and analyzed its tectonic development feature and evolution model. It is suggested that, the outcrop of the Dalongkou anticline core belong to a ＂fold-related fault＂, and the rock strength has an important effect on the tecton- ic deformation. Three types of special tectonic styles were typically developed in the outcrop, i.e., the Limb Wedge Group Structure, Similar Pop-up Structure and Separation Reverse Fold Structure.
