河北省老迷沟地区钼(银)矿远景区地球化学异常特征及找矿潜力分析

Geochemical anomly characteristics and potential of Laomigou Mo(Ag)property in Hebei province

1∶20万区域化探及区域地质调查成果显示,老迷沟地区为钼、银矿成矿远景区。文章通过对该区进行1∶1万土壤地球化学测量,发现Mo,Ag元素的均值及变异系数较高,且Mo,Ag元素的相关性也较高,综合化探异常由NE向和NW向的Mo,Ag异常带组成,有较多伴生元素叠加,规模较大,呈现较明显的浓集;槽探工程揭露已发现一定规模的钼矿化带,处于NE向断裂破碎蚀变带中,有向深部延伸的趋势。老迷沟地区成矿条件及地球化学环境较好,具有较大的钼(银)矿找矿潜力。

Both geochemical and geological surveys at scale 1 ： 200,0 00 reveal that Laomigou area is a potential Mo （Ag） property. Average content of Mo, Ag and the variation coefficient and correlation are relatively high. Integrated geochemical anomly in large scale comprises of NE and NW Mo, Ag anomalies and is accompanied by more by-product elements and concentration centers. Trenching encounters a Mo mineralization zone located in a NE altered cataclastic rock zone. The anomly over the zone is accompanied by Ag anomly and is caused by the mineralization which shows extension tendency to depth. Laomigou property is located in better geochemical setting thus potential for further prospecting.
