摘　　要：山东省萤石矿床类型主要有热液充填石英-萤石脉型、重晶石-萤石型、萤石-铅锌硫化物型3种,主要分布在胶北隆起区和胶南隆起区,其分布轮廓主要受位于两个隆起区西侧的郯庐断裂带控制。区内断裂构造发育,提供良好的成矿空间条件。山东省萤石矿的成矿来源主要是岩浆活动形成的富含Ca、F等元素的热水溶液,与中生代燕山晚期的岩浆活动关系密切。截至2021年底,山东省查明萤石矿产地13处,累计查明萤石矿石量为975.9万t,矿物量(CaF_(2))为334.61万t;保有萤石矿石量为519.17万t,矿物量(CaF_(2))为176.8万t,均已停采。Fluorite deposits in Shandong Province are mainly hydrothermal filling quartz-fluorite vein type,barite-fluorite type,fluorite-lead-zinc sulfide type 3,mainly distributed in the Jiao bei uplift area and the Jiao nan uplift area,and its distribution profile is mainly controlled by the Tantanlu fracture zone located in the west of the two uplift areas.Fracture tectonic development in the area,providing good spatial conditions for mineralization.The source of fluorite ore mineralization in Shandong Province is mainly the hot water solution rich in Ca and F formed by magmatic activities,which is closely related to the magmatic activities in the late Yanshan period of the Mesozoic Era.By the end of 2021,Shandong Province identified 13 fluorite ore production sites,with a cumulative identified fluorite ore amount of 9759000 t,and a mineral amount(CaF_(2))of 3346100 t;the retained fluorite ore amount of 5191700 t,and a mineral amount(CaF_(2))of 1768000 t,which have been stopped mining.
