摘　　要：针对准噶尔盆地南缘齐古断褶带复杂构造情况,开展了齐古断褶带构造演化研究。在广泛调研天山山体演化、周边地层发育、地表水流变更、地震解释剖面的基础上,以理论地质学为指导,结合研究区内头屯河三叠系—新近系的标准地层剖面、地面地质详查资料、重要地震勘探解释剖面、综合研究报告等资料,研究了喜马拉雅期齐古断褶带平面构造特征、齐古断褶带剖面构造特征,分析了齐古断褶带的主要构造特征,划分出了齐古断褶带的构造模式。研究认为:齐古断褶带构造演化可划分为四个阶段,依次为掀斜阶段、断褶阶段、滑脱阶段和楔入阶段。为齐古断褶带下步油气勘探提供了依据。Aiming at complex structure of Qigu fault-folded belts in Junggar Basin, structural evolution is studied in this paper. By investigating massif evolution of Mount Tianshan, stratum development of surrounding, the change of surface water, seismic interpret profile, regarding theoretical geology as guidelines, combining standard stratigraphic section of between Triassic and Neozoic, surface geology data, important interpretation profile of seismic exploration, integrated research report, plane and profile structural characteristics of Qigu fault-folded belts in the period of Himalaya are researched in this paper. The main structural characteristics of Qigu fault-folded belts is analysed and its structural model is divided. In this paper, it is considered that the structural evolution of Qigu fault-folded belts is divided into four stages, including tilt stage, fault-folded stage, detachment stage and wedging stage. It provides proof to exploration of Qigu fault-folded belts.
