摘　　要：霍尔果斯背斜、玛纳斯背斜、吐谷鲁背斜三大构造同属准噶尔盆地南缘山前断褶带第二排构造,在空间上呈"品"字型排列。根据断层相关褶皱理论和平衡剖面技术,建立霍玛吐三个构造的二维构造模型,整体解释对比三大构造新、老地震剖面及霍尔果斯、吐谷鲁背斜三维剖面,认为这排构造是早期褶皱与后期断层突破及中深部双重构造的叠加组合。Huoerguosi, Manasi and Tugulu anticlines belong to the second row of structures in piedmont thrust-fold belts in Junggar basin. By means of balance cross-section construction and fault-fold theory, 2D structural modes for these three anticlines are developed. The interpretation and correlation among them in old-new and 3D seismic profiles show that such a row structure is a superimposed combination shaped by early fold and late thrust breakthrough as well as mid-deep structures.
