monazite
This term refers to a specific mineral group prized primarily for its concentration of rare earth elements and thorium. It is used almost exclusively in geological, mineralogical, and industrial contexts, particularly regarding the extraction of cerium and lanthanum.
As a mass noun representing a mineral species, it is typically treated as uncountable when referring to the substance in general. To specify individual crystals or distinct deposits, practitioners use partitive constructions such as a grain of monazite or a crystal of monazite.
