中文摘要：
陕西省铧厂沟金矿是一个主要赋存于海底基性火山喷流细碧岩中的金矿床。在野外地质工作的基础上，对主矿带样品的测试数据进行了数学地质分析和原生晕分带序列计算。结果表明，Aull矿体的原生晕轴向分带序列从上至下为：Hg-Sb-Ni-As-Bi-Cu-Au-Co-Zn-W-Mo-Mn-Pb-Ag-Cd； Au8矿体的原生晕轴向分带序列从上至下为：Cu-Co-W-Au-Ni-Sb-Mn-As-Pb-Bi-Hg-Mo-Ag-Zn-Cd；并提出了主矿带理想原生晕分带序列：Sb-As-Cu-Hg（前缘晕）→Au-Ag-Bi-Pb-W（近矿晕）→Ni-Co-Mn-Mo-Zn-Cd（尾晕）。结合微量元素衬值空间变化规律，建立了2个矿体的原生晕叠加理想模型。Aull矿体在1150m中段以前缘晕和尾晕叠加为特征；在1110m中段，发育较强的尾晕。Au8矿体在1150m和1070m中段以前缘晕和尾晕叠加为特征；在1110m中段，矿体减薄，近矿晕减弱，发育很弱的前缘晕和尾晕。综合分析认为，Aull矿体到达中下部，向深部仍有一定延伸；Au8矿体已经接近尾部，深部可能存在新的矿体。
英文摘要：
On the basis of field geological work, the paper analyzes the microelements of the samples of the main ore zone, with the methods of geo-mathematic analysis and the calculation of the primary halo zoning. The result shows that the primary halo axial zoning sequence of ore body Aul I is Hg-Sb-Ni-As-Bi-Cu-Au-Co-Zn-W- Mo-Mn-Pb-Ag-Cd, and the primary halo axial zoning sequence of ore body Au8 is Cu-Co-W-Au-Ni-Sb-Mn-As- Pb-Bi-Hg-Mo-Ag-Zn-Cd. The ideal primary halo axial zoning sequence of the main ore zone is brought forward, which is Sb-As-Cu-Hg（ front halo elements）→Au-Ag-Bi-Pb-W（ near-ore hole elements）→Ni-Co-Mn-Mo-Zn-Cd （rear halo elements）. According to the characteristics of contrast halo zoning of the two ore bodies, the idealzoning models of the primary superimposed halos are built. In ore body Aul I, the front halo is coexistent with the rear halo in 1,150 m middle section, and the rear halo appears obviously in 1,110 m middle section. In ore body Au8, the front halo is coexistent with the rear halo in 1 , 150 m and 1,070 In middle sections; the near-ore halo is decreased in !, 110 m middle section with ore body thinning and the weakening of the front and the rear halos. According to the results mentioned above, ore body Aul 1 is extending to the deep part; the underlying part of ore body Au8 is not deep, but there is a new ore body in deep part.
