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。
The Huachanggou gold deposit in Shaanxi Province mainly occurs in the submarine volcanic jet billet. On the basis of field geological work, mathematical geoanalysis and primary halo zoning sequence calculation were carried out. The results showed that the combinations of halogens of Sb, Hg, As and Cu were the frontal halo elements, and the combinations of Au, Ag, Bi, The primary zonation axial banding sequence of the northern ore belt from top to bottom is Hg-Bi-Mo-Au-Ag-As-Cu-Pb-Co-W-Mn-Sb-Ni-Zn-Cd. Combined with the variation rule of trace elements in space, the ideal model of superposition of primary blues in the northern ore belt was established. Three small ore bodies A, B and C were developed from middle 950 m to middle 830 m. A orebody The tail part is overlapped with the head part of B orebody, while the distance between B and C ore bodies is relatively large. The middle part of 830 m has reached the tail part of the ore body and the ore body extends to the deep part.
