Keyword Definition

Monazite

Monazite refers to a group of monoclinic phosphates and arsenates, with the formula: MTO4, where M = REE, Th, Ca, Bi; T = P, As.  Individual minerals in this group include:

  • Monazite-(Ce):  Ce, La, Nd, Th)(PO4

  • Monazite-(La):  (La, Ce, Nd)(PO4

  • Monazite-(Nd):  (Nd, La, Ce)(PO4

  • Monazite-(Sm):  (Sm, Gd, Ce, Th)(PO4

The great majority of "monazite" is monazite-(Ce).  Monazite usually contains small amounts of Th or sometimes U, both making it radioactive.
