| 摘 要： | 巴彦宝力道金矿区位于内蒙古苏尼特左旗,区内发育与金矿化有关的破碎蚀变带和糜棱岩化带。通过研究地质及物化探工作成果,建立本区地球物理、地球化学成矿模式,采用相关分析和“格氏法”等方法,确定了矿床元素轴向分带序列为:As-Sb-Hg-Bi-Li-Sr-Ba-Ag-Pb-Au-Cu-Zn-Sn-V-Co-Cr-Ni-Ti-Mo-W,前缘晕元素为As、Sb、Hg、Bi,主成矿元素为Au、Cu、Zn,尾晕元素为 Ti、Mo、W。据轴向分带特征,确定金矿体剥蚀程度的判别指标为w(As)×w(Sb)×w(Bi)/w(Ti)×w(Mo)×w(W)。建立了找矿标志,为下一步地质找矿提供了依据。

| Abstract: | The Bayanbaolidao gold ore district lies in Sonid Left Banner of Inner Mongolia.The fractured alteration zone and the mylonitized zone are related to gold mineralization of this area.On the basis of geological, geophysical and geochemical achievements,geophysical and geochemical exploration models were constructed.With correlation analysis and "Geshifa" method, the axial zoning sequence of the elements is defined as As-Sb-Hg-Bi-Li-Sr-Ba-Ag-Pb-Au-Cu-Zn-Sn-V-Co-Cr-Ni-Ti-Mo-W.The front halo elements are As,Sb,Hg and Bi.The essential elements that form the mineral deposit are Au, Cu and Zn.The rear halo elements are Ti,Mo and W.According to the axial zoning characteristics,the criterion for the denudation extent of the gold deposit is w(As)×w(Sb)×w(Bi)/w(Ti)×w(Mo)×w(W).The determination of ore-prospecting criteria provides the basis for further geological exploration. |
