摘　　要：福建将乐三溪萤石矿床赋存在F1北东向断裂内,晚侏罗世中细粒正长花岗岩与成矿关系密切,围岩蚀变主要为硅化、叶蜡石化等中低温热液蚀变组合,矿床成因类型属中低温热液充填型脉状萤石矿床。区内成矿地质条件有利,萤石成矿具有多期性,矿区西部矿体仍有向深部延伸的趋势,推测矿区东部萤石矿体被F2错位到了深部。因此认为矿区东部2~6勘查线以及深部具有良好的找矿前景,建议矿山继续开展勘查工作。The Sanxi fluorite deposit in Jiangle,Fujian,is hosted within the NE-trending F1 fault.The late Jurassic medium-fine grained syenogranite has a close relationship with mineralization.The wall rock alterations are mainly low to medium temperature hydrothermal alteration assemblages such as silicification and pyrophyllitization.The genetic type of the deposit belongs to the low to medium temperature hydrothermal filling vein-type fluorite deposit.The metallogenic geological conditions in the area are favorable,and fluorite mineralization is polyphasic.The ore bodies in the western part of the mining area still show a trend of deep extension.It is speculated that the fluorite ore bodies in the eastern part of the mining area have been displaced to deeper parts by F2.Therefore,it is considered that there are good prospecting prospects in the exploration lines 2~6 in the eastern part of the mining area and at depth.It is recommended that the mine continue to carry out exploration work.
