|Name:||From the Greek μονάζει "to be solitary" in allusion to the rarity of its presence in the first known localities.|
Unclassified members of the Monazite Group. See also: Monazite-(Ce),Monazite-(La),Monazite-(Nd),Monazite-(Sm), Unnamed (Gd-dominant monazite),
The name monazite, without a elemental suffix, was the accepted name for all material in this group, regardless of the REE-bearing components' relative abundance. The suffixes were added when the naming convention for all REE-bearing members was devised and implemented.
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)".
