Processing of xenotime concentrate

Hydrometallurgy, 1998
Xenotime is a rare earth phosphate mineral which is a rich source of yttrium and heavy rare earths. Earlier experimental studies have been carried out in this laboratory on the chemical processing of hand-sorted xenotime obtained from the Bihar region to rare earth oxide intermediates.

Shocker: xenotime can date impacts

2023
Constraining precise ages for impact events is crucial in establishing Earth’s history, and several geochronometers have been developed to date impacts. We present electron backscatter diffraction (EBSD), sensitive high-resolution ion microprobe (SHRIMP) and atom probe tomography (APT) data from shocked xenotime [(Y,HREE)PO4] collected from ...

Response of xenotime to prograde metamorphism

Contributions to Mineralogy and Petrology, 2011
Xenotime is a widespread accessory mineral in lower greenschist to upper amphibolite facies metasedimentary rocks from the Palaeoproterozoic Mount Barren Group, southwestern Australia. Xenotime is closely associated with detrital zircon, commonly forming syntaxial outgrowths, in samples of sandstone, micaceous quartzite, slate, phyllite, garnet-bearing

An empirical garnet (YAG) – xenotime thermometer

Contributions to Mineralogy and Petrology, 2000
A pronounced negative correlation between the yttrium concentration in garnet ([Y]Grt) and temperature has been observed in xenotime (YPO4)-bearing metapelites from central New England, USA. The [Y]Grt decreases roughly two orders of magnitude (∼5500 to less than 100 ppm Y) over a 150 °C interval. A regression of ln([Y]Grt) against estimated reciprocal
