摘　　要：德里特地区位于东昆仑南构造带东段,成矿地质条件较好。在研究区内采用地面高精度磁测和激电剖面测量的合物探方法对该区进行找矿预测,结合地质成矿条件,发现了6条含矿蚀变带,圈出42条矿体,成因均与构造热液有关。在综合找矿成果的基础上,建立了地质-地球物理找矿模型,以成矿地质体+高磁异常+高极化率+中-低电阻率为找矿标志,对研究区矿产进行找矿预测,可取得较好的找矿成果。The Derite area is located in the eastern section of the South Kunlun tectonic belt,characterized by favorable metallogenic geological conditions.In this study,a combination of high-precision surface magnetic survey and induced polarization profile survey using geophysical prospecting methods was employed for exploration and prediction purposes.By integrating the geological and metallogenic conditions,six ore-bearing alteration zones and 42 orebodies were identified,all associated with tectonic hydrothermal processes.Based on comprehensive prospecting results,a geological-geophysical prospecting model was established.Utilizing indicators such as ore-forming geological bodies+high magnetic anomalies+high polarization+medium-low resistivity enables more effective mineral prospecting predictions within the study area.
