摘 要 通过矿山实地调查、收集并研究湖南省现有的萤石地质资料后可知,至2017年底,湖南省已发现萤石矿床44处;累计查明储量16911.3203万吨,保有储量12471.1834万吨;保有资源量大,位居全国第一;但开发利用率很低,仅为26.26%。成因类型主要有岩浆热液充填型萤石矿和矽卡岩型钨锡矿床伴生萤石矿。成矿时代集中在燕山期,且主要为燕山晚期。湖南省萤石矿的找矿工作,主攻类型应以热液充填型单一萤石矿为主;找矿重点应是湘东、湘南地区。

Abstract: According to the field survey of the existing fluorite geological data in Hunan , by the end of 2017, 44 fluorite deposits had been discovered. The total proved reserves were 16.91 million tons and the retained reserves are 12.47 million tons. The retained reserves were ranking the first in China; But the rate of exploitation and utilization was low, only 26.26 percent. The main genetic types are magmatic hydrothermal filling fluorite deposits and skarn tungsten-tin associated fluorite deposits. The metallogenic epoch is concentrated in the Yanshanian Period, and mainly in the late YanshanianPeriod.The prospecting work of fluorite ore should focus on hydrothermal filling type.The prospecting area should focus on Eastern and Southern Hunan.

湖南省螢石矿勘探开采历史悠久,长期被地质学者重视。基于“湖南省非金属矿产资源利用现状调查及发展规划”和“中国矿产志”项目,通过矿山实地调查、收集并研究湖南省现有的萤石地质资料,对湖南省萤石资源的分布和利用现状进行总结,分析资源潜力,指出找矿方向,为进一步开展湖南省萤石资源开发利用工作提供决策依据。
1 资源储量及分布
湖南省有已查明萤石资源储量的矿床数44个,分布在郴州市、岳阳市、衡阳市、张家界市、株洲市、邵阳市、长沙市和益阳市8个市州,其中40个已建成矿山,4个为未占用矿区。矿床类型主要为岩浆热液型,其次为矽卡岩型。矿床规模大、中、小型皆有,以中小型为主。矿物组成累计查明储量16911.3203万吨,采损量4440.1369万吨,保有储量12471.1834万吨。(表1)。
另外,全省已发现具有一定找矿潜力的萤石矿点7处,分布在岳阳市(3处),郴州市(2处),常德市(2处)。……
