摘要:  瑞昌南阳地区位于江西九江—瑞昌成矿带内,区内已发现武山铜矿、城门山铜矿,具有“多位一体”的成矿特征。结合南阳地区土壤地球化学测量、EH4电磁测深、激电中梯测量、高精度磁测成果,对该区主要成矿空间与区域成矿特征进行了对比,认为区内深部具有较好的成矿条件。对区内物化探异常特征进行了详细分析,并布置了钻探工程进行物化探异常验证,在预期部位见到了硫化铜矿化体。结合该区物化探异常特征、地质特征与区域典型矿山地质特征、矿化特征的对比分析,指出了南阳地区找矿突破的主攻方向。

Abstract: The Nanyang Area of Ruichang City is located in the JiujiangRuichang metallogenic belt.Wushan Copper Deposit and Chengmengshan Copper Deposit are found in the belt,which is presented with multiple metallogenic geological characteristics.The soil geochemical survey method,EH4 electromagnetic sounding method,IP intermediate gradient method and highprecision magnetic survey are used in this area,based on the above geophysical prospecting results,the comparison analysis of the main metallogenic space and regional metallogenic characteristics is done,which indicated that the metallogenic conditions of the depth of the Nanyang Area is good.The regional geophysical and geochemical anomaly characteristics is analyzed in detail,and the anomalies are verified by using drilling engineering,the copper sulfide mineralized body is found in the expected position.Based on the regional geophysical and geochemcial characteristics and geological characteristics,and the comparison analysis results of these characteristics and geological and mineralization characteristics of the regional typical mines,the main prospecting directions and prospecting potential of Nanyang Area are discussed.
