【摘要】 江西仙姑台铜多金属矿位于九瑞矿集区,是近年整装勘查区中发现的斑岩—矽卡岩—热液充填型铜多金属矿床。本文在系统分析其成矿地质背景、控矿条件、找矿标志、土壤地球化学及地球物理等特征的基础上,归纳并提取了矿床的找矿信息。根据前二者基本可以圈定找矿区段,再结合1∶1万土壤异常、1∶1万高精度磁测上延50 m磁异常、激电探测视极化率与视电阻率异常,以及EH-4连续电导率剖面测量异常等多元信息,便能较为有效地确定隐伏矿体的大致分布位置。依此建立了仙姑台铜多金属矿床的综合勘查模型,对该区寻找此类矿床有着十分重要的意义。更多还原

【Abstract】 The Xiangutai copper polymetallic deposit is located in the Jiujiang-Ruichang ore concentration area,Jiangxi Province. It is a porphyry-skarn-hydrothermal filling type copper polymetallic deposit found in the integrated exploration area in recent years. Analyzing systematically the ore-forming geological background,ore-controlling conditions,prospecting indicators,and soil geochemical and geophysical characteristics,this paper induces the deposit prospecting information. The prospecting region can be delineated by the oreforming geological background and ore-controlling conditions, and the general distribution of concealed orebodies can be more effectively delineated coupled with multiple anomalies based on 1 ∶10 000 soil survey,1 ∶10 000 high-precision magnetic survey( upward continuation to 50 m),IP detection of apparent chargeability and the apparent resistivity,and EH-4 continuous conductivity profile measurements. Therefore,it is very important to establish a comprehensive prospecting model in the search for such deposits in the study area.更多还原
