| 中文摘要: |
| 本文通过在西藏邦卓玛地区开展的1:10000土壤地球化学测量工作，运用元素的变化系数、元素富集离散特征对邦卓玛地区土壤地球化学测量的12种微量元素进行地球化学统计分析，论述了12种微量元素的成矿潜力，得出Au、Ag、W、Pb、Sb5种元素具有较大的成矿潜力，并通过相关分析、因子分析确立了测区内元素组合特征，共划分了三组主成矿元素组合（即Au-Ag-Cu-Bi-W；Pb-Sn；Sb），运用衬值异常法在区内圈定组合异常，结果显示，组合异常明显，异常套合较好，大体呈NW向串珠状展布，根据组合衬值异常叠加，在研究区内圈定了4个重点靶区，为下一步在该区内寻找Au、Ag、Sb、W、Pb等多金属矿提供了理论依据。 |
