  • Bastnäsite Wikipedia

    Bastnäsite is closely related to the mineral series parisite. The two are both rareearth fluorocarbonates, but parisite's formula of Ca(Ce, La, Nd) 2 (CO 3) 3 F 2 contains calcium (and a small amount of neodymium) and a different ratio of constituent could be viewed as a formula unit of calcite (CaCO 3) added to two formula units of bastnäsite.
