摘　　要：根据龙首山地区的岩矿石电性、磁性参数,结合区内铀成矿模式等建立了地电及地磁等地球物理模型,对模型进行了正反演计算,对其结果的电、磁性特征进行了科学合理的定性分析,建立了区内铀矿找矿有利地段的地质-地球物理模型。对S01线实测数据进行了处理及解释,推断了断裂构造的位置、产状,对闪长岩分布范围进行了推断解释,圈定了铀找矿有利地段,收到良好的效果。Electrical model and magnetic model are built by the resistivity and magnetic capacity characteristics of rock.Based on these model,magnetic and electric characteristics are analyzed.It usually tends to form a tectonic fracture,low resistivity and magnetic anomaly in the favorable uranium metallogenic.Builds the uranium deposits geology-geophysical prospecting model of uranium deposit with uranium geology and geophysical characteristics.Through the practice and test,the result shows that fault structure and intrusive rock could be well detected by using the AMT and ground magnetic survey.This proved that it is effective for detecting the favorable uranium area by the uranium deposits geology-geophysical prospecting.
