  • Monazite: Mineral information, data and localities.

    www.mindat.org/min-2750.html The great majority of "monazite" is monazite-(Ce), the La-, Nd-, Sm- and Gd-dominant members are all very rare. Monazite usually contains small amounts of Th or sometimes U, both making it radioactive. For "monazite-(Y)", see písekite-(Y) (this has a pyrochlore structures and thus is not a member of this group).
