中文摘要:
      巴斯湖铅锌矿位于青海省西南部唐古拉山北坡,三江成矿带西段。依据1∶5万地球化学测量资料,对巴斯湖铅锌矿中7种成矿指示元素的分布、相关性、组合异常等特征进行了分析研究,结果显示巴斯湖地区Pb、Zn、Ag等中低温热液元素呈明显富集状态,为区内主要成矿矿种,结合地质特征,圈出2处铅锌综合异常,9条铅锌矿化体,说明研究区具有良好的寻找铅锌矿的地球化学条件,同时也说明粒级为-10~+60目的1∶5万地球化学测量工作可以在区内发挥良好的找矿指导作用,这对巴斯湖以及整个三江成矿带西段的下步找矿勘查工作都具有很好的借鉴指导作用。
英文摘要:
      The Basihu Pb-Zn deposit is located in the north slope of Tanggula mountain in the southwest of Qinghai province, in the western segment of the Sanjiang Metallogenic Belt. Based on the 1∶50,000 geochemical survey, The distribution, correlation and assemblage anomalies of seven metallogenic indicator elements in Basihu Pb-Zn deposit were analyzed and studied. The results showed that the medium and low temperature hydrothermal elements such as Pb, Zn and Ag were obviously enriched in the Basihu area, is the main metallogenic minerals, Combined with geological features, Two comprehensive anomalies and nine ore body of Pb-Zn were identified. It indicates that the study area has good geochemical conditions for searching for Pb-Zn ore. At the same time, it also indicates that the 1∶50,000 geochemical survey with a grain size of -10 ~ +60 can play a good guiding role in ore prospecting in the region. This will be a good reference for the next step of prospecting and exploration in Basihu and the whole western segment of the Sanjiang region.
