| 摘 要： | 原生晕法在长期大量的勘探实践中，已被证明是一种有效推测隐伏矿体，进行找矿预测的地球化学勘探方法.在永新金矿床的勘查基础上，通过采集永新金矿区内见矿效果最好的180号勘探线上的4个钻孔的岩石样品，开展了钻孔原生晕的分析.确定了该矿床前缘晕元素组合为As-Sb-Hg，近矿晕元素组合为Au-Ag-Cu-Pb-Zn，尾矿元素组合为W-Mo-Bi-Co-Ni-Cd.与前人总结的金矿经典分带模型相比，前缘晕出现了尾晕元素，同时尾晕序列中也有前缘晕的元素出现，显示了"反分带"的特征，说明在矿体的头部和尾部均有盲矿存在，而依据矿体发育形态来看，矿体头部继续往南东的盲矿已被剥蚀，而矿体尾部往北西方向是下一步勘查的重点.

| Abstract: | Primary halo has proved to be an effective geochemical exploration method for concealed orebodies prediction and prospecting by a number of long-term practices. Based on the exploration of Yongxin gold deposit, the paper analyzes the primary halo of drill holes by collecting rock samples from four boreholes along the No. 180 exploratory line with the best ore-discovery in the area. The results define the front halo element association of As-Sb-Hg, near-ore halo of Au-Ag-Cu-Pb-Zn and rear halo of W-Mo-Bi-Co-Ni-Cd. Compared with the typical zoning model of gold deposits summarized by previous researchers, the existence of rear halo elements in front halo and the front halo elements also in rear halo sequence shows the reverse zoning feature, indicating the blind ores exist in both the upper and lower of orebody. As the blind ores in the upper part to southeast has been denuded according to the orebody developing form, further exploration should focus on the lower part to the northwest. |
