摘要:综合利用人工和天然地震剖面解释,地面地质资料分析,揭示了位于塔里木盆地西北缘的南天山库孜贡苏
断陷盆地的形成与演化过程。结果显示,库孜贡苏断陷为北北西向的伸展断陷,其断陷结构为西断东超的箕状断
陷,一直延伸到库孜贡苏断陷内部。库孜贡苏断陷盆地反映了中生代和新生代两期的变形。剖面平衡恢复和构造
建模研究指出研究区在中新生代以来东西方向缩短量为38.51km,缩短率为46.11%。

Abstract:Based on various data such as2D seismic profile and field geologic survey,the structural features and evolution process of the Kuzigongsu downfaulted basin,which located in northwestern margin生活方式对健康的影响
of Tarim Basin,Southern Tienshan has been disclosed.The study indicates that the Kuzigongsu downfaulted is the NNE trending extensional fault depression,and the fault depression structure is a west-faulting east-overlapping’s dustpan-shaped rift,and stretches inland to Kuzigongsu downfaulted.The Kuzigongsu downfaulted basin reflects two periods of Mesozoic and Cenozoic deformation.Based on structural deformation analyzing and balanced section technology,this area has been shortened38.51km (from east to west)since Cenozoic,and its shortening rate is46.11%.
Keywords:the Kuzigongsu downfaulted basin;structural characteristics;balanced cross-section;northwestern margin of Tarim Basin
