| 中文摘要: |
| 南庄铅锌矿床的发现丰富了豫西南二郎坪群的矿产。为明确下一步找矿方向，也为在该区寻找类似矿床提供地质参考，本文在分析区域地质、矿区地质及矿体地质特征的基础上，总结了矿床成矿规律，发现该矿床的矿体多数呈隐伏状，主要产于火神庙组石英角斑凝灰岩中，层控特性明显，同时与古火山机构和褶皱构造关系密切，矿化富集和蚀变特征具一定的规律性。本文总结了综合找矿标志，初步建立了找矿模式，指出 IN含矿蚀变带深部、VD含矿蚀变带及其东段和IIC含矿蚀变带具有很大的找矿潜力。 |
| 英文摘要: |
| The discovery of the Nanzhuang lead-zinc deposit has enriched the mineral resources of the Erlangping Group in southwestern Henan. In order to clarify the future prospecting direction and provide a geological reference for finding similar deposits in this area, this article summarizes the metallogenic laws of the deposit based on the analysis of regional geology, mining area geology and geological characteristics of the ore body, and discovers the ore body of the deposit. Most of them are concealed, mainly produced in the quartz keratophyre of the Huoshenmiao formation, with obvious stratification characteristics, and are closely related to ancient volcanic structures and fold structures. The mineralization enrichment and alteration characteristics have certain regularities. We summarized the signs of comprehensive prospecting, and initially established a prospecting model. It was pointed out that the deep part of the IN ore-bearing alteration zone, the VD ore-bearing alteration zone and its eastern section, and the IIC ore-bearing alteration zone have great prospecting potential. |
