大别山地区萤石矿地质背景及地球化学特征探讨

文章通过研究区内萤石矿床(点)地质背景、矿体特征与部分萤石矿及围岩样品的主量、稀土和微量元素的测试分析,系统总结了大别山地区萤石矿床地质特征,初步了解区内萤石矿及围岩的岩石地球化学特征。研究表明,该地区燕山期的中酸性花岗岩是区内萤石矿成矿母岩,断裂交汇部位是萤石矿重要的赋矿部位,矿化石英脉和萤石蚀变岩带是区内萤石矿(化)体的主要赋存形式,硅化作用与区内萤石矿(化)体的形成关系密切。

Discussion on geological background and geochemical characteristics of fluorite deposit in Dabieshan area

This paper systematically summarizes the geological characteristics of fluorite deposits in the Dabieshan area by studying the geological background of fluorite deposits (points), the characteristics of ore bodies and the main quantities of rare fluorite and surrounding rock samples, rare earths and trace elements. To understand the geochemical characteristics of the fluorite ore and surrounding rocks in the area. The study shows that the Yanshanian medium-acid granite in the area is the fluorite ore-forming parent rock in the area. The intersection of the fracture is an important ore-bearing part of the fluorite ore. The mineralized quartz vein and the fluorite altered rock zone are the fireflies in the area. The main form of occurrence of quarry (silver) body, silicification is closely related to the formation of fluorite ore in the area.
