• Bastnäsite - Wikipedia

    en.wikipedia.org/wiki/Bastn%C3%A4site The mineral bastnäsite (or bastnaesite) is one of a family of three carbonate-fluoride minerals, which includes bastnäsite-() with a formula of (Ce, La)CO 3 F, bastnäsite-() with a formula of (La, Ce)CO 3 F, and bastnäsite-() with a formula of (Y, Ce)CO 3 F. Some of the bastnäsites contain OH − instead of F − and receive the name of hydroxylbastnasite.
