萤石的研究现状及其地质学意义

The Research Status of Fluorite and Its Geological Significance

摘要: 随着世界氟化工的快速发展，氟化工行业以其产品具有高性能、高附加值而被誉为“黄金产业”。作为一种重要的非金属矿产资源，主要成分为CaF2的萤石成为工业上提取氟的主要来源，萤石丰富的色彩，强大的发光性使其在宝石市场也占据一定的地位。从上世纪40年代开始，各路学者便展开了对萤石矿床的深入研究，到如今我国多个省市都发现了许多大小不一的萤石矿床，由于各地的地貌差异萤石矿的成因和种类也各不相同。本文先简要论述了萤石的宝石学特征、颜色成因、世界产地分布及其在实际生活中的用途，初步介绍了萤石矿选方法，萤石在世界上的产地众多，我国作为全球萤石产量最多的国家之一，本文通过结合前人文献总结出我国产出的三类主要萤石矿产类型——沉积改造型、热液充填型和伴生型，再以河南萤石矿产、内蒙古萤石矿产和湖南萤石矿产研究了萤石矿床的分布地区，成矿期，成矿类型，最后结合全文分析了我国萤石矿产的研究现状及延伸出相关地质学意义以及萤石矿产的发展。

Abstract: With the rapid development of the world’s fluorine chemical industry, the fluorine chemical in-dustry is known as the “golden industry” for its high performance and high added value. As an important non-metallic mineral resource, fluorite, which is mainly composed of CaF2, has become the main source of industrial fluorine extraction. The rich color of fluorite and its strong luminosity make it occupy a certain position in the gem market. Since the 1940s, scholars from various fields have carried out in-depth research on fluorite deposits. Many fluorite deposits of different sizes have been discovered in many provinces and cities in China. Due to the differences in geomorphology, the genesis of fluorite deposits and the types are also different. This paper briefly discusses the gemological characteristics, color genesis, distribution of world origin and its use in real life. The fluorite ore mining method is introduced. The fluorite is produced in the world. China is a global fluorite. One of the countries with the highest output, this paper summarizes the three main types of fluorite minerals produced in China by combining the predecessor literature—sedimentary transformation type, hydrothermal filling type and associated type, followed by Henan fluorite mineral and Inner Mongolia fluorite. Minerals and Hunan fluorite minerals have studied the distribution area of fluorite deposits, metallogenic period, metallogenic types, and finally combined with the full text to analyze the research status of fluorite minerals in China and extend the relevant geological significance and the development of fluorite minerals.
