Xenótimo (Xenotime). Xenótimo, xenotímio ou xenotímia (do grego xenos, "estranho", e time, "honra") é um mineral raro composto de fosfato de í, com fórmula química YPO4. Forma uma solução sólida com a chernovite-(Y) (YAsO4) e portanto pode conter impurezas vestigiais em que se incluem arsénio, dióxido de silício e cálcio; as terras raras …

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). (2) The content of thorium is lower than that in monazite (Table 13). (3) The composition of tungsten-containing xenotime …

A more robust approach combines a regional structural framework with precise high-resolution, in situ U–Pb geochronology of monazite and xenotime because these phosphate minerals are commonly cogenetic with sulfide mineral assemblages hosting gold and have a bulk closure temperature for U–Pb well above 600 °C (Vielreicher et al. …

Xenotime-(Y) and monazite are common accessory phosphates that control the rare earth element (REE) budget in many rocks. Whereas monazite preferentially incorporates the light REE (LREE) from La to Gd, the xenotime incorporates the heavy REE (HREE) from Tb to Lu (Ni et al. 1995).For monazite, the REE patterns are steep with a negative slope …

Monazite and xenotime are the main REE-bearing minerals found in these deposits. The refractory character and high density of these minerals enabled their chemical preservation during transportation from the eluvial sites, where there was mechanical weathering of the parent rock materials, to their placer (depositional) sites [59, 60]. The ...
