水地球化学测量在森林沼泽景观区区域化探异常追踪中的作用研究

Study on the Role of Hydrogeochemical Survey for Tracing Regional Geochemical Anomaly in Forest and Swamp Landscapes

对水地球化学测量在森林沼泽景观区域化探异常追踪阶段的地位和作用进行了研究，发现了水体中热液型铅锌矿床和铜金矿化、斑岩型铜矿床的指示元素种类。以相对低密度（0．5点／km^2－2点／km^2）和小采样量（每点25ml）的水地球化学测量可达到快速有效缩小找矿靶区、指明找矿有利区段、指导下一步工作部署的目的。

The significance and action of hydrochemical survey on follow - up for regional anomaly in forest and swamp landscape were researched. It was fond that hydrochemical guide elements to the hydrothermal Pb - Zn, Cu - Au deposits and porphyry copper deposits. The hydrogeochemical survey with lower density （0.2 - 2 sample/ km^2 ） and less quantity （ 25 ml per sample） could rapidly reduce useful targets and indicate favorable place for EX- PLORATION.
