摘要
根据水系沉积物测量结果,结合地球化学图,介绍了溜河地区Au、Ag、Cu等18种元素的地球化学参数特征及空间分布特征,通过R型聚类分析介绍了测区18种元素的相关组合特征并对组合异常进行圈定,分析了测区地球化学异常特征,阐述了以金为主的内生矿产在次生晕、构造、破碎带及矿化蚀变等方面的找矿标志。
According to the measurement result of water system sediments, combined with geochemical map, the author introduced the characteristics of geochemical parameters and spatial distribution characteristics of 18 elements, such as Au,Ag,Cu and so on, while introduced the correlation characteristics of 18 elements in testing zone through R type cluster analysis and it made delineation of combinatorial anomaly. The characteristics of geochemical anomalies in testing zone are analyzed. The prospecting indicators of gold endogenic minerals in secondary halos were explained, structutes, fractured zones and mineralization alteration.
