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。
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.
