| 摘 要： | 为了探索播卡深部的找矿空间及找矿方向,本文在播卡矿区钻孔样品分析数据的基础上,研究了播卡金矿床的元素富集规律、元素组合、元素异常在地表及空间的分布特征,建立了播卡金矿的原生晕分带模型、地球化学勘查模式,提出了不同深度的原生晕判别指标,在此基础上对播卡金矿的深部隐伏矿体进行了预测。结果显示播卡金矿的深部及邻区具有寻找隐伏矿体的良好前景。

| Abstract: | In order to better explore the ore prospecting space and direction in the depths of the Boka gold deposit,element enrichment regularity,element association,surface and spatial distribution characteristics of element anomalies were studied in this paper based on geochemical analytical data of some drilling samples in the Boka gold deposit.In addition,primary halo zoning model,geochemical exploration model and primary halo discrimination indicators of ore bodies in different depths of the deposit were built up subsequently.On this basis,deep-concealed ore bodies in the Boka gold deposit have been predicted,and the result shows that the depths and adjacent areas of the Boka gold deposit have good potential for prospecting of deep-concealed ore bodies. |
