摘要: 中富萤石矿是江西省近年来探明的一处大型萤石矿床,其矿床地质特征和控矿因素 研究较薄弱。通过分析中富萤石矿床地质特征,浅析控矿因素。结果表明:中富萤石矿矿体形态 和产状受控于构造破碎带,宽破碎带处矿体厚度往往也随之增大。矿石矿物为萤石,脉石矿物主 要为石英;矿石结构以破碎结构、碎斑结构等为主,构造以块状构造、条带构造、角砾状构造等为 主;矿石类别包括萤石型、石英—萤石型和萤石—石英型。研究区内萤石矿床的成矿作用与区内 地层、岩浆岩、构造紧密相关,其三位一体作用联合控制着萤石成矿流体的形成、沉淀和富集。研 究区内断裂众多,同时岩浆岩十分发育,这些因素有利于区内萤石矿的形成。

Abstract: The Zhongfu Fluorite Deposit is a large-scale fluorite deposit discovered in Jiangxi Prov⁃ ince in recent years. Its geological characteristics and ore-controlling factors are poorly studied. By analyz⁃ ing the geological characteristics of Zhongfu Fluorite Deposit, the ore-controlling factors are analyzed. The results show that the shape and occurrence of the ore body of Zhongfu Fluorite Deposit are controlled by the structural fracture zone, and the thickness of the ore body at the wide fracture zone tends to increase. Ore minerals are fluorite and gangue minerals are mainly quartz. The ore structure is mainly broken structure and porphyroclastic structure, and the structure is mainly block structure, strip structure and breccia struc⁃ ture. Ore types include fluorite type, quartz-fluorite type and fluorite-quartz type. The mineralization of flu⁃ orite deposits in the study area is closely related to the strata, magmatic rocks and structures in the area, and its trinity jointly controls the formation, precipitation and enrichment of fluorite ore-forming fluids. There are many faults in the study area, and magmatic rocks are well developed. These factors are condu⁃ cive to the formation of fluorite deposits in the area.

Key words: fluorite, ore-forming regularity, ore-controlling factors
