摘　　要：　锡林郭勒金成矿带颇具找矿潜力,文章总结了成矿带的地球物理、地球化学特征,采用数理统计分析方法,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As×Sb×Bi/Ti×Mo×W。根据研究成果部署的深部钻探工程取得了较好的找矿效果。Xilinguole Au belt in the middle of Nei Monggol is of great potential. By analysing geophysical and geochemical results and geophysical and geochemical feature of Au deposits in the belt and adopting math statistical analysis As-Sb-Hg-Bi-Li-Sr-Ba-Ag-Pb-Au-Cu-Zn-Sn-V-Co-Nr-Ti-Mo-W, the axial ore element zoning is determined with As, Sb, Hg, Bi, as the head halo elements, Au, Cu, Zn, as the main ore element and Ti, Mo, W as end elements. According to the axial zoning As×Sb×Bi/Ti×Mo×W is the criteria for denutation degree of Au ore bodies. Ore exploration engineerings based on the above mentioned have shown good results.
