摘　　要：本文的研究工作围绕聊城许营区域内的重磁异常数据展开了深入且细致的探索。本研究充分利用了已知的物性参数等资料,详细剖析了该区域的重磁场特征;同时,紧密结合该地区的具体地质特征及所呈现的异常情况,以此对成矿问题展开深入讨论。值得一提的是,在山东齐河—禹城地区,近年来不断有矽卡岩型富铁矿被发现,聊城许营地区和齐河禹城地区有着相似的地质条件,二者都受到西侧聊考断裂的控制,属于同一构造单元,重点对比了二者的地球物理场特征,并且深入分析了与铁矿相关的地球物理找矿标志之间的相关性。通过这些工作,清晰地展现了在聊城许营地区开展重磁工作找矿的有效性,这也为今后重磁异常技术在类似地质勘查场景中的应用提供了极具价值的参考。This paper presents a comprehensive and in-depth investigation of the heavy magnetic anomaly data in the Xuying region of Liaocheng.In the course of the study,the known physical parameters were employed in order to conduct a comprehensive analysis of the heavy magnetic field characteristics of this region.Furthermore,these analyses are integrated with the geological context,the location,and the anomalies of the region to facilitate a comprehensive discussion of the metallogenic problem.It is noteworthy that in the Qihe-Yucheng area of Shandong province,the occurrence of skarn-type iron ore deposits has been documented on an ongoing basis in recent years.The geological conditions of the Liaocheng Xuying area and the Qihe Yucheng area are analogous,with both regions exhibiting a fault along the western margin and belonging to the same tectonic unit.The study compares and analyzes the two geophysical field characteristics and the correlation between the geophysical prospecting markers associated with iron ore.It demonstrates the effectiveness of heavy magnet prospecting in the Xuying area of Liaocheng and provides a valuable reference for the application of heavy magnet anomaly technology in similar geological exploration scenarios in the future.
