| 摘 要： | 在分析矿床地质特征的基础上,结合前人资料探讨了栖霞山铅锌多金属矿的成矿物质来源、控矿因素和矿床成因。成矿流体主要由来自深部的含矿热液、源自石炭—二叠系碳酸盐岩的有机流体和地表渗流雨水组成。其中,有机流体在矿物沉淀富集过程中起到较为重要的作用。矿体主要受纵向断裂F2、上下构造层之间不整合面和石炭—二叠系碳酸盐岩地层控制,认为在栖霞山深部,沿纵向断裂F2的延伸方向仍有较大找矿空间。

| Abstract: | Based on the analysis of the geological properties of the ore deposit, the authors discussed the ore-forming material sources, ore control factors and the genesis of the deposit in combination with the previous study. The ore-forming fluid was composed of orebearing hydrothermal fluid from deep source, organic fluid from C-P carbonate rock and meteoric water. The organic fluid played an important role in the precipitation and enrichment of ore forming elements. The ore body was controlled by longitudinal fault (F2), unconformity surface over and under the structural layers and C-P carbonate rock. It was concluded that in the deep part of the deposit, there was prospecting potential along the extension of longitudinal fault (F2). |
