| 中文摘要: |
| 原生晕找矿方法自20世纪80年代以来，在我国地质勘查领域得到广泛关注与应用，是被公认为寻找盲矿体和深部矿床最具前景的技术手段之一。 本研究以完肯金矿为研究对象，通过系统开展代表性勘查线剖面原生晕测量工作，建立了矿区主矿体的原生晕垂直轴向分带序列。 研究结果表明，矿区元素分带序列自上而下依次为：（Bi、Hg、W）→（Au、As、Cu）→（Ag、Mo、Pb、Sb）→Sn→Zn。 进一步分析显示，矿区前缘晕元素主要富集于矿体中上部，近矿晕元素集中分布于中下部，而尾晕元素在矿体上部和下部均有出现。 这种独特的元素空间分布特征揭示了完肯金矿具有多期次叠加成矿的特点，为深入认识矿床成因机制和指导深部找矿提供了重要依据。 |

| The primary halo prospecting method has garnered significant attention and application in China's geological exploration sector since the 1980s, being widely recognized as one of the most promising technical approaches for detecting blind ore bodies and deep -seated deposits. This study focuses on the Wanken Gold Deposit, where a vertical axial zoning sequence of primary halos for the main ore body was established through systematic primary halo measurements conducted on representative exploration line profiles. The results demonstrate that the element zoning sequence in the mining area progresses from top to bottom as: （Bi, Hg, W） →（Au, As, Cu）→（Ag, Mo, Pb, Sb）→Sn→Zn. Further analysis reveals that front halo elements predominantly concentrate in the upper-middle sections of the ore body, proximal halo elements cluster in the middle-lower portions, while tail halo elements appear in both upper and lower sections. This distinctive spatial distribution pattern of elements indicates the characteristic of multi-stage superimposed mineralization in the Wanken Gold Deposit, providing critical evidence for understanding the deposit's genetic mechanisms and guiding deep-level prospecting efforts. |
