内蒙古金蟾山矿电吸附法找矿与有利区预测

    Exploration and play fairway prediction of the Jinchanshan mine in Inner Mongolia using electro-adsorption method

    • 摘要: 为评价金蟾山矿区资源潜力,应用电吸附方法对金蟾山矿区2条化探剖面土壤样品进行金属元素含量测试分析。结合矿区地质条件,通过研究化探剖面土壤金属元素含量特征,得出以下结论:已知矿床上方Au、Ag、Cu、Pb、Zn呈明显正异常,元素异常区与矿体对应良好,证实该技术方法在该区有效、可行;研究发现矿区1线剖面拐棒沟—阳坡—小西沟矿化带西边见Ⅰ、Ⅱ两处化探异常,2线剖面夹于拐棒沟—阳坡—小西沟矿化带和南大洼—李麻子沟—漏风峁矿化带中间地段及该剖面最西端见Ⅲ、Ⅳ两处化探异常,综合矿区地质情况分析,Ⅰ、Ⅲ两个异常区成矿地质条件良好,是有利的勘查区。通过本次有利区预测,为该矿区下一步的勘查指明了方向。

       

      Abstract: To evaluate the resource potential of the Jinchanshan mining area, this study conducted analysis and tests of metal element content in soil samples from two geochemical profiles using the electro-adsorption method. By combining the geological conditions of the mining area, this study revealed pronounced positive geochemical anomalies of Au, Ag, Cu, Pb, and Zn above the known gold deposits. The anomalous areas corresponded well with deposits, confirming the effectiveness and feasibility of the electro-adsorption method in the study area. The study identified geochemical anomalies Ⅰ and Ⅱ to the west of the Guaibanggou-Yangpo-Xiaoxigou mineralization zone in the first geochemical profile. Along the second profile, located between the Guaibanggou-Yangpo-Xiaoxigou and Nandawa-Limazigou-Loufengmao mineralization zones, anomalies Ⅲ and Ⅳ were observed at the westernmost end. The comprehensive geological analysis of the mining area indicates that the Ⅰ and Ⅲ anomaly zones exhibit favorable geological conditions for mineralization, serving as play fairways. The play fairway prediction conducted in this study provides targets for future exploration in the mining area.
