Metallogenic Geological Conditions and Status of Exploration and Development of Fluorite Deposits in Shandong Province
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 9 759 000 t,and a mineral amount(CaF2)of 3 346 100 t;the retained fluorite ore amount of 5 191 700 t,and a mineral amount(CaF2)of 1 768 000 t,which have been stopped mining.
