| 中文摘要: |
| 内蒙古中西部地区横跨华北地台和内蒙地槽两个大地构造单元, 华北地台北缘是我国重要的多金属成矿带, 成矿地质背景优越, 贵金属矿床类型多样, 找矿潜力巨大。文章作者通过野外地质工作, 首次在地槽区宝音图岩群地层中发现了金银矿, 并对恼楞金银矿地质特征、地球化学特征、矿体特征及金银的赋存状态进行了初步研究, 总结了矿床成因及控制因素, 探讨了其成矿时代。 |
| 英文摘要: |
| In geotectonic term, the middle-west area of Inner Mongolia crosses over the two tectonic units, i.e., North China platform and Inner Mongolia geosynclines. Among them, the North China platform is one of key polymetallic metallogenic belt, where there are favorable mineralization conditions and varieties of precious metal deposits occur and thus there is great prospecting potential in the platform. Through the field exploration, the Naoleng gold-silver deposit was first found in the Baoyintu Group strata within Inner Mongolia geosynclines by the authors. Based on the integrated study of geological characteristics, geochemical characteristics, ore-body characteristics and the mineral phases of gold and silver in the Naoleng gold-silver deposit, the metallogenic mechanism, genesis and ore-controlling factors were summarized in this paper and finally the mineralization age was discussed. The study result will guide the further exploration work in the region. |
