摘　　要：本文对龙湖萤石矿区的地质背景、矿床特征及矿床成因进行了研究分析。研究显示:燕山期岩体为研究区提供了矿物质来源;南华—震旦系洪山组变质岩在燕山期岩体活动时为岩体的矿物质源提供了屏蔽空间;构造破碎带及次级断裂构造为该矿区提供了导矿通道及赋存空间。结合龙湖萤石矿的矿床成因分析认为,矿液在充填断裂带的同时也充填次级断裂构造机制,提出了对断裂构造带充填型脉状萤石矿床的找矿分析。This paper studies and analyzes the geological background,deposit characteristics and ore genesis of Longhu fluorite mining area.Research shows that the Yanshanian rock mass provided mineral sources for the study area.The Metamorphic rock of the Hongshan formation of the Nanhua Sinian system provided shielding space for the mineral source of the rock mass during the Yanshanian rock mass activity.The structural fracture zone and secondary fault structures provide a guiding channel and occurrence space for the mining area.Based on the ore genesis analysis of Longhu fluorite deposit,it is considered that the ore fluid fills the fracture zone and also fills the secondary fault structure mechanism.
