Euxenite is a rare mineral, which is also referred to as euxenite-y and euxenite-(Y) or Yttriomicrolite. This mineral is typically found in igneous rocks, granitic pegmatites, and alluvial sediments. With its black or brown color, Euxenite is known for its high content of rare earth metals, including yttrium, niobium, and tantalum. Some possible synonyms for Euxenite include yttrium-niobium-tantalum oxides, yttrobetafite and betafite, Yttrian columbite, and niobite. Additionally, Euxenite can be associated with other rare minerals such as epidote, magnetite, apatite, and monazite.
