摘要
安徽庐江县鸭池山萤石矿属中低温热液充填型矿床。本文通过地质调查、电子探针及流体包裹体分析等手段,揭示了鸭池山萤石矿矿石特征与成矿机制。该矿石成分以萤石、石英、方解石为主,含少量绿泥石、硫铁矿等,矿石呈细粒脉状、团块状构造。成矿流体源于热液与深部流体混合,早期岩浆演化与晚期流体作用对高品位矿体形成起关键作用。矿体沿控矿断裂及岩体接触带分布,反映控矿构造与岩体侵位的关联。该成果为庐江及周边萤石矿勘查提供了理论依据。
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.
