摘要

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, the authors also collect aero-magnetic data of this region, and study the crystalline basement of basin and orogenic belts and the characteristics of tectonicdivisions.  The 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.
