Abstract： The Chongping Fluorite Ore in Hezhou City is located in the southern end of the Guposhan composite rock body at the northeast corner of the Dayao Mountains uplift， the Central Guangxi-Northeast Guangxi fold system and the Nanhua Active Belt， and the lithology in the area is single， and it is late Jurassic syenite granite. The northeast trending fault zone provides a migration pathway and enrichment space for mineral bearing hydrothermal fluids， while magmatic activity provides a source of material for fluorite mineralization. The fluorite deposit in this area is a medium to low temperature hydrothermal filling type vein deposit， and its ore type is quartz-fluorite type.
