中文摘要：
陕西省铧厂沟金矿主要赋存于海底基性火山喷流细碧岩中。在野外地质工作的基础上,进行了数学地质分析和原生晕分带序列计算。结果表明,Sb、Hg、As、Cu为前缘晕元素组合,Au、Ag、Bi、Pb、Zn为近矿晕元素组合,Co、Ni、W、Mo、Mn、Cd为尾晕元素组合;北矿带原生晕轴向分带序列从上至下为：Hg-Bi-Mo-Au-Ag-As-Cu-Pb-Co-W-Mn-Sb-Ni-Zn-Cd。结合微量元素衬值空间变化规律,建立了北矿带的原生晕叠加理想模型：在950 m中段到830 m中段之间自上而下发育A、B、C三个小矿体;A矿体尾部和B矿体头部叠加在一起,而B、C两个矿体间隔的距离较大;830 m中段已经到达矿体尾部,矿体向深部延伸较小。
英文摘要：
The Huachanggou gold deposit of Shaanxi Province occurs in the submarine basic volcanic effusive spillite.Based on field geological work in the Huachanggou gold deposit,this paper analyzes trace elements of the samples in the north ore zone by such means as geo-mathematic analysis and calculation of the primary halo zoning.The result shows that the front halo elements are Sb,As,Cu,Hg,the near-ore halo elements are Au,Ag,Bi,Pb,W,and the rear halo elements are Ni,Co,Mn,Mo,Zn,Cd.The primary halo axial zoning sequence from the top to the deep part of the north ore zone is Hg-Bi-Mo-Au-Ag-As-Cu-Pb-Co-W-Mn-Sb-Ni-Zn-Cd.According to the characteristics of threshold halo zoning,the ideal zoning model of the primary superimposed halos is built.Three ore bodies（A,B and C） appear in the area form the 950m level down to the 830m level.The tail of ore body A is stacked on the top of ore body B,while ore body C is far away from ore body B.The tail of the ore body C appears at the 830m level,and the its downward extension is not large.
