摘要
最早在八卦庙地区进行1/5万分散流普查找矿时发现了多元素分散流异常;在用1/2万化探次生晕扫面检查异常时发现了Ag异常;在用1/万分散流检查Ag异常时发现了Au异常。在初期发展过程中化探原生晕起到了指导布设工程、布置采样的作用。从金矿的发现发展来看寻找金矿的有效方法:发现异常→确认异常→发现矿体→探明矿床(结合金矿普遍规律,含矿岩石与周围岩石有明显差异来圈定含矿岩石的分布范围,达到快速探明矿体的目的)。
Multi-elements dispersion train anomalies have been found in the survey by1：50000 dispersion trains in Baguamiao area,silver anomalies have been found in the 1：20000 geochemical secondary halos examination and,gold anomalies have been detected in 1：10000 dispersion strain examination to check the silver abnormals. During the early days of this progress,geochemical primary halo took the role of guiding the project layout and sampling position design. From the process of discovering and developing the gold mine,we concluded that the effective method for finding the gold deposit is：discovering the anomalies-examine,verifying the former anomalies,finding the ore body,prospecting the ore body.
