Monazite, a rare earth phosphate mineral is another source of rare earth elements. There are four main varieties of monazite: monazite-Ce, monazite-La, monazite-Nd and monazite-Sm. Monazite may also contain thorium making it radioactive. Monazite occurs as a rather rare accessory mineral in certain granitic rocks and pegmatite veins.
