摘要
为解决秦岭柳梢沟矿区深部找矿问题,在柳梢沟金矿区开展了电化学找矿研究,利用衬度异常法等地质统计学方法对地电提取数据进行处理。结果表明,在3个不同矿区的已知矿体上方集中出现了明显的地电提取的主成矿元素异常及衬度累加异常,说明地球电化学勘查找矿方法是有效的。结合矿区地质特征和主成矿元素的关系,初步建立了秦岭柳梢沟隐伏金矿地电化学理想找矿模型,并在已知矿体外围开展隐伏矿预测工作,圈出了4处具有找矿前景的异常靶区。
For deep prospecting in Liushaogou district, a variety of geo-statistics methods are used for data pro-cessing, such as statistical method, contrast anomaly method and so on.The research on 3 known district shows that the clear anomalies of major ore-forming elements and accumulative contrast anomaly are found above the known ore body.The method is effective in prospecting concealed ore deposit.According to the relationship be-tween geologic setting and major ore-forming elements, ideal geo-electrochemical prospecting model is set up for gold deposits in Liushaogou district.Besides, four exploration targets are in the peripheral zone.
