xenotimeREE
XenotimeREE is a term used in mineralogy to refer to xenotime minerals that contain notable concentrations of rare earth elements (REEs). Xenotime itself is a phosphate mineral with a general composition expressed as (REE, Y)PO4, where the REE component includes yttrium and heavier lanthanides. In practice, xenotimeREE denotes varieties in which one REE is dominant, leading to end-member names such as xenotime-(Y), xenotime-(Dy), xenotime-(Er), xenotime-(Yb), and xenotime-(Tm).
Chemically, xenotimeREE minerals crystallize in the tetragonal system and typically appear as brown to yellow-brown crystals
Occurrence and exploration emphasize xenotimeREE as a potential source of heavy REEs, which are critical for
In mineral nomenclature, xenotimeREE can be labeled as xenotime-(REE) to reflect the dominant rare earth in
