Monazite, xenotime, and allanite are REE1-minerals sensu stricto because lanthanides (La…Lu) and yttrium are critical constituents in them. Apatite does not require REE, but because it contains substantial REE in many rocks, it is included in this review. All four minerals also host unusually high radionuclide concentrations, notably Th and U, forming the basis of their utility as geochronometers.

This quartet of accessory minerals is playing an increasingly important role in petrochronology because they provide ways to link robust spot ages to petrogenetic (P–T) conditions so can lend petrogenetic context to chronology based on other minerals....
