青海都兰红旗沟金矿床构造叠加晕深部找矿预测

摘要

The Hongqigou gold deposit is a typical one in the Au-bearing altered cataclastic rock zone Ⅸ in the Wulonggou ore deposit-clustered area in Qinghai province.Based on analysis of element combination,characteristics of the element correlation variation,distribution of primary halo in the ore-hosting structure,elements zoning and vertical and axial zoning sequence variation law and the primary halo superimposition characteristics is discussed the ore fluid geochemistry and built the ore prospecting model.Then the second enrichment zone in the deposit is located and the favorable ore-hosting space is predicted to depth.It is still potential to depth.%红旗沟金矿床是青海省五龙沟矿集区Ⅸ号含金破碎蚀变带中的典型金矿床.文章通过对矿床元素组合、元素相关变化特点及主矿体赋矿构造中原生晕分布、组分分带、垂(轴)向分带序列变化规律、原生晕叠加特点等地球化学特征的综合分析,探讨了该矿床成矿热液活动地球化学规律和找矿标志模型,圈定了矿床深部第二富集带及矿化带深部有利盲矿赋矿空间,预测矿区深部具有较大的找矿潜力.
