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
