    The classification of fluorite deposits in China

    • 摘要: 通过对中国萤石矿床的成矿作用研究, 综合考虑萤石矿床的成因类型和工业类型, 将中国萤石矿床划分为沉积改造型、热液充填型和伴生型3种矿床类型。在全面分析萤石矿典型矿床的成矿条件、控矿因素和成矿作用的基础上, 总结成矿要素, 以相同或相似的二级成矿必要要素组合确定沉积改造型、热液充填型萤石矿床的亚类型, 沉积改造型进一步划分出2个矿床式, 热液充填型划分出5个矿床式, 伴生型按伴生主矿种划分出4个矿床式。文章分析了每一个矿床式的成矿地质背景, 成矿条件、矿床特征、控矿因素和成矿作用, 总结了每一个矿床式的二级成矿必要要素。

       

      Abstract: The fluorite deposits have been divided into three types, i.e., sedimentary-reformation type, hydrothermal fluid filling type and accompanying type on the basis of studying ore-forming process of the ore deposits and synthesizing their genetic types and industrial types. Based on an analysis of the ore-forming conditions, ore control factors and mineralization of characteristic fluorite deposits, this paper summarizes metallogenic factors. And then the sedimentary-reformation deposits and hydrothermal fluid filling deposits have been divided into subtypes. The sedimentary-reformation deposits are classified into two deposit types, the hydrothermal fluid filling deposits into five deposit types and accompanying deposits into four deposit types according to principal commodity. Ore-forming geological background, ore-forming conditions, deposit features, ore-control factor and mineralization of each deposit type are analyzed, and the secondary and necessary factors of mineralization are summarized.
