| 摘 要： | 阴山造山带与鄂尔多斯盆地跨越不同的构造单元,是典型的盆、山耦合地带,且是构造活动强、弱的变异地域,了解该区结晶基底分布特征对于深化认识盆山耦合的深部要素和深层动力学过程具有十分重要的意义.本文在最新的高精度的地磁观测剖面和数据采集基础上,与航磁异常场在该区域上的展布进行集成研究.通过磁场特征分析以研究盆地和造山带地域的构造分区和结晶基底起伏,进而对该区的油、气能源和金属矿产资源分布特征及前景进行探讨.这一研究成果为进一步深化认识该区的深部构造格局及其深层动力学过程提供了深部介质磁性结构与属性的重要判据.

| Abstract: | Yinshan orogen and the northern Ordos basin cross different tectonic units, they are typical of basin-mountain coupling zones and transition regions between strong and weak tectonic activities. As a result, the knowledge of the distribution of crystalline basement is of vital importance to identifying and understanding of deep factors contributing to basin-mountain coupling zone as well as deep dynamical processes. Based on updated and highly accurate observational data of geomagnetic profile, we also collect aero-magnetic data of this region, and study the crystalline basement of basin and orogenic belts and the characteristics of tectonic divisions. Then we discuss the distribution features and good prospects of energy and resources in this region. The research results will inevitably provide solid evidence of magnetic structure and properties for further research on this region, including the internal structure and the deep dynamical processes. |
