| 中文摘要: |
| 阴山位于西南三江成矿带的最南段,区域上是重要的铜、铅、锌、金、银矿床集中区。作者以孟连地区已知矿床控矿构造为出发点,利用阴山1∶25 000土壤地球化学测量数据进行R型因子分析,得出4组与成矿有关的元素组合,再以因子得分为基础,圈定该区异常,从而得出下一步找矿方向:与原生金矿或红土型金矿有关的因子F3(Au-As)；与隐伏斑岩型钼铜矿床有关的因子F2(Mo-Cu)；与热液型铜铅锌金银有关的因子F1(Zn-Bi-Sb-Mn-Co-W-Pb-Cu-As)和F4(Ag-Pb)。 |
| 英文摘要: |
| The Yinshan area located in the most southern part of three rivers metallogenic belt in southwestern China, is an important mineralization cluster area of copper, lead, zinc, gold and silver deposits. On the basis of ore-controlling structures of known deposits in Menglian area, four groups related to ore-forming elements combination are obtained by using R-mode factor analysis for the soil geochemical survey data on a scale of 1∶25 000 in Yinshan area.Then abnormal zones are defined by multiplying factor score which provide prospecting direction in the next stage exploration:1) F3 factor (Au-As) is closely related to primary gold deposit or laterite type gold deposit； 2)F2 factor (Mo-Cu) possibly indicates concealed porphyry Mo (Cu) deposit； 3)F1 factor (Zn-Bi-Sb-Mn-Co-W-Pb-Cu-As) and F4 factor (Ag-Pb) both indicate hydrothermal Cu-Pb-Zn-Au-Ag deposit. |
