摘　　要：甘肃省萤石资源较丰富,主要分布在金塔县北、高台县东北以及永昌县西至天祝县西北一线,萤石品位变化较大。本文在收集和整理以往萤石矿相关资料的基础上,结合近几年萤石矿勘查成果,通过对省内已发现和评价的29处萤石矿的地质特征、控矿因素及成矿时代等分析研究,共划分了6个萤石成矿区带,并总结和分析了各成矿区带的地质特征及找矿潜力。为今后开展省内萤石找矿及研究提供参考。Gansu province is rich in fluorite resources,mainly distributed in the north of Jinta county,the northeast of Gaotai county,and the west of Yongchang county to the northwest of Tianzhu county and the ore grade changes greatly.On the basis of collecting and sorting out the related data of fluorite mines in the past,combined with the exploration results of fluorite mines in recent years and the division results of metallogenic belt in Gansu province,this paper makes a detailed analysis of the geological characteristics,ore-controlling factors and metallogenic age of 29 fluorite mines discovered and evaluated in Gansu province.and divides 6 fluorite metallogenic belts and the geological characteristics and prospecting potential of each metallogenic belt are summarized and analyzed.It provides reference for fluorite prospecting and research in the future.
