Fluorite formation
WebFluorite is a mineral that mostly occurs in hydrothermal veins. The chemical composition is very simple: CaF 2. It is not very common mineral because fluorine (F) makes up only 0.06% of the mass of the crust and there are other minerals … WebMar 14, 2024 · According to the modern concept about the structure of nonstoichiometric fluorite phases M1−xRx F 2+x, the defects formed as a result of heterovalent isomorphic replacement of M2+ cations by R3+ cations are grouped into clusters. The anion core of the clusters consists of interstitial anions.
