为解决米泉地区构造复杂、地震资料缺乏及品质差导致的地质建模难问题，以岩石物性研究为基础，将重磁电等资料与地震资料进行联合研究；在构造解析理论的指导下，根据区域构造背景和露头标定建立初始模型，通过电震联合解释和重磁震资料的联合反演不断修改完善模型，建立了米泉地区的“后缘为基底卷入的厚皮冲断-前缘为盖层滑脱褶皱”构造模型。研究表明：米泉地区具有“南北分带”的构造特征，自南向北划分为3个带：造山隆起带、山前冲断带和前缘滑脱带。

To resolve the problem of geology modeling caused by complex tectonic deformation,insufficient seismic data,and poor seismic quality in Miquan area,the data of gravity,magnetic,electric and the seismic data were integrated and investigated based on the petrophysical properties.In the guidance of structural analysis theory,the initial model was built according to the regional tectonic background and outcrop calibration,the model was continuously improved by means of electric-seismic integrated inter-pretation and gravity-magnetic-seismic joint inversion,and the Miquan’s geology model of back edge deep thrust resulted from basement engulfing-front edge cap detachment fold was built.The results showed that the Miquan area had tectonic features of belting in south-north,it was divided into three zones from south to north:the orogenic uplift belt,foreland thrust belt,and the frontal detachment zone.
