Monazite is a reddish-brown phosphate mineral containing rare earth metals. It occurs usually in small isolated crystals. There are actually at least four different kinds of monazite, depending on relative elemental composition of the mineral:
monazite-Ce (Ce, La, Pr, Nd, Th, Y)PO4
monazite-La (La, Ce, Nd, Pr)PO4
monazite-Nd (Nd, La, Ce, Pr)PO4
monazite-Sm (Sm, Gd, Ce, Th)PO43
monazite-Ce (Ce, La, Pr, Nd, Th, Y)PO4
monazite-La (La, Ce, Nd, Pr)PO4
monazite-Nd (Nd, La, Ce, Pr)PO4
monazite-Sm (Sm, Gd, Ce, Th)PO43
