| 为揭示重金属元素的迁移和富集规律，指导黄金资源的勘探与开发，以某金矿床深部矿储层为研究对象，在分析其地质构造、主要出露地层及深部矿储层所处区域的基础上，对其重金属元素富集特征与空间分布进行研究。通过重金属元素富集系数揭示其富集特征；运用ArcGIS 9.0软件绘制空间插值图，描述重金属元素的空间分布。结果显示：区内Cr不富集，As、Ni、Pb、Zn较低富集，Cd、Cu一般富集，Hg中度富集，说明区内深部矿储层重金属元素分布不均匀，可能是地质构造、岩石类型、人为活动等因素影响所致；重金属元素含量受上层有机质内负电荷吸附等影响，总体随金矿储层深度的增加而下降。 |

| Abstract: |
| To reveal the migration and enrichment patterns of heavy metal elements and guide the exploration and development of gold resources, this study takes the deep ore reservoirs of a gold deposit as the research object. Based on an analysis of its geological structure, main exposed strata, and the region where the deep ore reservoirs are located, the enrichment characteristics and spatial distribution of heavy metal elements were investigated. The enrichment characteristics were revealed using the enrichment factor of heavy metal elements; the spatial distribution was described using spatial interpolation maps generated with ArcGIS 9.0 software. The results show that: Cr is not enriched in the area; As, Ni, Pb, and Zn show low enrichment; Cd and Cu show moderate enrichment; and Hg shows moderate enrichment, indicating an uneven distribution of heavy metal elements in the deep ore reservoirs of the area. This uneven distribution may be influenced by factors such as geological structure, rock type, and human activities. The content of heavy metal elements is influenced by factors such as adsorption by negatively charged sites in upper organic matter, and generally decreases with increasing depth of the gold ore reservoirs. |
