Xenotime - an overview | ScienceDirect Topics
Xenotime, a phosphate ore, is one of the valuable mineral deposits of rare earths similar to monazite. The main characteristics of xenotime are listed below: (1) The content of yttrium is high while that of the light rare earths is low ( Table 12 ).
Xenotime: Mineral information, data and localities. - mindat.org
The traditional name for this species, almost exclusively referring to xenotime-(Y) (the species xenotime-(Yb) is very rare). The X-ray powder diffraction pattern is similar to that of atelisite-(Y) .
Hydrothermal formation of heavy rare earth element (HREE)–xenotime …
2018年1月24日 · As xenotime is notoriously insoluble, the question arises as to whether these lesser-known deposits form at typical basin temperatures or by influx of much hotter magmatic-hydrothermal fluids. The Browns Range District in northern Western Australia hosts deposits of xenotime that are enriched in HREEs and also uranium.
The Maw zone rare earth element (xenotime) deposit is hosted in brecciated sandstones in the Athabasca Basin and is associated with silicification, hematitization, and tourmalinization (magnesiofoitite).
Geochemical characterisation of xenotime formation environments …
2018年5月5日 · Within the data from the giant Mt. Tom Price deposit (Fig. 16), there is a broad trend of low U and U/Th in the oldest xenotime, and then progressively higher U and U/Th for younger xenotime in the same orebody.
Hydrothermal Rare Earth Element (Xenotime ... - GeoScienceWorld
2017年9月1日 · The Maw zone rare earth element (xenotime) deposit is hosted in brecciated sandstones in the Athabasca Basin and is associated with silicification, hematitization, and tourmalinization (magnesiofoitite).
Understanding geologic processes with xenotime: Composition, chronology ...
2008年9月15日 · Xenotime grows in sediments during diagenesis, in low- to granulite-grade metamorphic rocks, in migmatites, and is common in peraluminous igneous rocks. Xenotime can be a complement, or indeed an alternative, to monazite and/or zircon in geochemical and geochronological studies.
Age, geological setting, and paragenesis of heavy rare earth …
2019年5月2日 · The vein-type xenotime (X2) present in most deposits/prospects returned mainly concordant, but slightly younger ages at ca. 1620 Ma, albeit with some overlap within uncertainty of the breccia-hosted xenotime age.
Hydrothermal monazite and xenotime chemistry as genetic
2023年12月29日 · Notable differences in overall xenotime abundances and concentrations of heavy REEs, Ca, and Sc are distinctive between the different deposit classes for xenotime.
Occurrence, Geology, Mineralogy, and Processing of Monazite, Xenotime …
2022年12月23日 · Monazite, Xenotime, Apatite, and Rhabdophane are each explored through lists of conducted research to develop a synopsis of their characteristics and notable geological deposits.
