1. Endogenesis: mainly formed by hydrothermal process, and generated with metal sulfide and carbonate at medium and low temperature. There are two types of hydrothermal fluorite deposits: first, calcite is the main biogenic mineral in view of fluorite veins in limestone, but it is seldom used. Sometimes it is mixed with barite and lead zinc sulfide for half a life. The other is aimed at fluorite veins produced in rhyolite, granite and schist, and calcite is less in biogenic minerals, mainly in time;
2. Sedimentation: Bedding occurs in sedimentary rocks containing gypsum, anhydrite, calcite and dolomite, or in sandstone as cements and detrital minerals.
