摘　　要：在相山火山盆地1:5万物化探数据基础上,通过对已知铀矿床的平面和剖面物化探异常特征分析,系统总结了相山铀矿床的物化探异常特征,构建了相山铀矿床的物化探异常模型,并以此为依据建立了相山铀矿田高放射性异常、高地球化学元素异常、高磁异常、电阻率异常陡变、重力异常陡变及低阻异常为异常特征的“三高二陡一低”物化探找矿模式,为相山地区铀矿勘查中物化探方法的应用提供了依据,也为该地区的铀成矿预测及钻探工程部署提供了技术支撑。Based on the geophysical and geochemical data with the scale of 1:50000 in Xiangshan volcanic basin,this paper systematically summarized the characteristics of geophysical and geochemical anomalies at Xiangshan uranium deposit by analyzing the characteristics of geophysical and geochemical anomalies of the known uranium deposit in plane and profile,and constructed the geophysical and geochemical anomaly model of Xiangshan uranium deposit.Based on the above results,the geophysical and geochemical prospecting model named“Three-high with two-steep and one-low”was established,the model is characterized by high radioactivity anomaly,high geochemical element anomaly,high magnetic anomaly,steep change of resistivity anomaly,steep change of gravity anomaly and low resistivity anomaly.This prospecting model will not only provide a basis for the application of geophysical and geochemical exploration methods in uranium exploration in Xiangshan area,but also the technical support for uranium metallogenic prediction and drilling engineering deployment in this area.
