研究区经1 5万水系沉积物测量化探取样,根据样品测试结果共圈定4个Pb、Zn化探异常区,结合室内综合数据整理及野外异常成因分析,得出该地区Pb、Zn异常分3种类型:密西西比河谷型(MVT)、热液充填型和花岗斑岩型。其中,密西西比河谷型(MVT)异常区具有分布面积大、强度高、相关元素叠加性好的特点,是该地区铅锌矿的一级找矿前景区。
According to the test results of the samples, a total of 4 Pb and Zn geochemical anomalous zones were delineated. Combined with the comprehensive indoor data and the analysis of the causes of the anomalies in the field, the Pb and Zn anomalies in the area were obtained Three types: Mississippi Valley (MVT), hydrofill and granite porphyry. Among them, the Mississippi Valley-type (MVT) anomaly area is characterized by large area of distribution, high intensity and good superimposition of relevant elements, which is the primary prospecting prospect for lead-zinc deposits in the area.
