	MONAZITE (Cerium Lanthanum Thorium Neodymium Yttrium Phosphate)
		Monazite is a primary ore of several rare earth metals most notably thorium, cerium and lanthanum.
		Monazite is radioactive, sometimes highly radioactive, and specimens are often metamict.
		Monazite, as already mentioned, forms in phosphatic pegmatites but is actually a standard trace constituent in many ordinary igneous, metamorphic and vein filling rocks.

	UMass monazite research
		Monazite dating using the electron microprobe has become increasingly popular over the past decade, especially as a tool for constraining the age of deformation or metamorphic events.
		Detailed compositional mapping of individual monazite grains reveals micro-domains wich can often be linked to microstructures, metamorphic minerals, or metamorphic reactions, allowing specific timing constraints to be placed on stages in the structural or metamorphic history.
		At UMass, we are carrying out monazite dating as part of mapping and tectonic analysis of the Western Churchill Province, Canada, in the Southwestern US, and collaboratively in a number of other areas around the world.
