浅钻地球化学勘查方法在红花尔基钨矿勘查中的应用效果

Application effect of shallow drilling geochemical exploration method in Honghuaerji tungsten ore exploration

内蒙古东北部半干旱草原荒漠区,浅覆盖层主要为风积砂土层,造成在金属矿产勘查过程中地质填图测量、土壤地球化学测量、水系沉积物地球化学测量等手段难以取得显著的效果。而在红花尔基钨矿勘查过程中,通过实践证明浅钻地球化学勘查方法在该类地球化学景观区内能够有效、快速的圈定地球化学异常区,能够辅助地质工作填制基岩地质图,同时确定矿化蚀变范围及进一步缩小找矿靶区,应用效果显著。

In the semi-arid grassland desert area of Northeast Inner Mongolia,the shallow overburden is mainly aeolian sandy soil layer,which makes it difficult to achieve remarkable results by means of geological mapping survey,soil geochemical survey and stream sediment geochemical survey in the process of metal mineral exploration.In the exploration process of Honghuaerji tungsten deposit,the practice has proved that the shallow drilling geochemical exploration method can effectively and quickly delineate the geochemical anomaly area in this kind of geochemical landscape area,assist the geological work to fill in the bedrock geological map,determine the mineralization alteration range and further narrow the prospecting target area,and the application effect is remarkable.
