Fluorite
Fluorite or fluorspar is the mineral form of calcium fluoride (CaF 2).The mineral may occur as massive (Fig. 1.15) or vein-type deposit, in association with metallic minerals forming a part of mineralization.The associated minerals include barite, calcite, quartz, galena, sphalerite, and pyrite (Fig. 1.16).The vein-type mineralization is of hydrothermal origin.
