摘　　要：在对准噶尔盆地南缘及邻区构造演化和对地震等地球物理资料分析的基础上 ,研究了该区中新生界构造样式 ,识别出压缩、走滑和反转三大构造样式类型。根据构造样式空间分布 ,对构造变形在平面上的东西分段性与南北分带性、垂向上变形的差异性以及走滑扭动变形特征和扩展方式进行了研究。该区油气成藏条件优越 ,构造控油作用明显 ,山前冲断带的断层相关褶皱。Three structural styles, including compression, strike slip and inversion, are identified in the southern margin of Junggar basin based on analysis of structural evolution and seismic interpretation in this area and adjacent area. According to the spatial distribution of these structural styles, the E W segmentation and S N zonation of structural deformations, vertical differences of deformations, as well as deformational features of strike slip wrench movement and their extending patterns have been studied. This area has favorable hydrocarbon accumulation conditions, and the control of structures on hydrocarbons is remarkable. The favorable exploration areas include fault related folds in piedmont thrust zones, anticlinal structures in the footwalls of piedmont thrusts and the anticlinal structures in the outer zone of piedmont thrust belt.
