Lanthanum minerals

Astrocyanite-(Ce) is a bright blue mineral with the chemical formula . Its type locality is Kamoto East Open Cut, Kamoto, Kolwezi, Lualaba, Congo

Monazite-(La) is a relatively rare representative of the monazite group, with lanthanum being the dominant rare earth element in its structure. As such, it is the lanthanum analogue of monazite-(Ce), monazite-(Nd), and monazite-(Sm). It is also the phosphorus analogue of gasparite-(La). The group contains simple rare earth phosphate minerals with the general formula of ATO4, where A = Ce, La, Nd, or Sm (or, rarely, Bi), and B = P or, rarely, As. The A site may also bear Ca and Th.

Belovite-(La) () is the lanthanum analogue of belovite-(Ce). It is a member in the belovite group being a subgroup of the apatite group.
