【摘要】 南安集海背斜和南玛纳斯背斜属于准噶尔南缘山前中西段第一排构造带,构造变形异常强烈,呈典型的堆跺式双重构造.通过应用断层相关褶皱的构造几何分析方法,用计算机对南安集海-南玛纳斯背斜带内的基干地震剖面进行了构造解析,南玛纳斯背斜是在霍-玛-吐断裂上叠加一堆跺式双重构造组成,向西南玛纳斯背斜上的堆跺式双重构造逐渐消失,同时霍-玛-吐断裂位移量逐渐转换成反向逆冲断层,形成南安集海背斜的复合型构造三角楔.通过构造解析,弄清了它们在三维空间中的过渡转换关系,对后继的南缘山前构造带的勘探开发具有参考意义.更多还原

【Abstract】 Southern AnJiHai anticline and Southern MaNaSi anticline belong to the first row of middle-west tectonic zone near southern Junggar Basin. Its tectonic deformation is intensive, presenting a typical antiformal duplex. By using the structural geometric model method of folding related to fault, we constructed the geological outline of Southern Anjihai -Southern Manasi anticline belt by analyze the skeleton seismic profile of this region. Southern Manasi anticline is built up by a antiformal duplex on Huo-Ma-Tu fault, and die out to the west. At the same time the displacement of Huo-Ma-Tu fault transmit to backward thrust gradually, and formed the Southern Anjihai compound structural triangle wedge. In the process of constructing structural configuration and tectonic assemble mode , we raveled the transition relationship in three -dimensional space of Southern Anjihai-Southern Manasi anticline, and it has very important reference and supervise sense to the subsequent exploration and development processes near southern Junggar Basin.更多还原
