Abstract
The Yachishan fluorite deposit in Lujiang County,Anhui Province,is a medium-low temperature hydrothermal filling-type deposit.This study,based on geological surveys,electron probe analysis,and fluid inclusions analysis,systematically investigates the ore characteristics and mineralization mechanisms.The ore is primarily composed of fluorite,quartz,and calcite,with minor chlorite and pyrite,exhibiting fine-grained vein-like and agglomerated textures.Mineralization resulted from the mixing of hydrothermal and deep-source fluids,where early magmatic evolution and subsequent fluid activity were critical for high-grade ore formation.Ore bodies are spatially associated with fault systems and intrusive rock contacts,highlighting the structural and magmatic controls.These findings establish a theoretical foundation for fluorite exploration in the Lujiang region and adjacent areas.关键词
