• Xenotime - Wikipedia

    en.wikipedia.org/wiki/Xenotime Xenotime is a rare-earth phosphate mineral, the major component of which is yttrium orthophosphate (Y P O 4).It forms a solid solution series with chernovite-(Y) (Y As O 4) and therefore may contain trace impurities of arsenic, as well as silicon dioxide and calcium.The rare-earth elements dysprosium, erbium, terbium and ytterbium, as well as metal elements such as thorium and uranium (all ...

    www.mindat.org/min-4333.html Xenotime-(Y) was found by the Norwegian mineralogist Nils Otto Tank (1800-1864) and first described by the Swedish chemist Jøns Jacob Berzelius in 1824 as Phosphorsyrad Ytterjord from a granite pegmatite at Hidra, Flekkefjord, Norway.Later, Glocker (1831) introduced the name Ytterspath.The name xenotime was finally coined by the French mineralogist François Sulpice Beudant (1832) in his 2 ...

    wgnhs.wisc.edu/minerals/xenotime-y Formula: YPO 4 Tetragonal Description: Xenotime-(Y) is a rare accessory mineral generally found in complex pegmatites. It resembles zircon in physical appearance and may be mistaken for it. It is noticeably softer than zircon, however. MARATHON COUNTY: Xenotime-(Y) has been reported as yellow to brown crystals up to 1 mm in diameter in pegmatites of the Nine Mile pluton, such as are exposed in ...

  • Xenotime - National Gem Lab

    nationalgemlab.in/xenotime Xenotime-(Y) is one of the very few yttrium gems. Xenotime is also a rare earth element (REE) mineral which means it contains some of the elements from the lanthanide series of elements. Although the chemstry of Xenotime is generally accepted as YPO4, analysis by electron microprobe reveals trace amounts of the REE elements dysprosium (Dy),

    www.dakotamatrix.com/mineralpedia/8314/xenotime-y Xenotime-(Y) The yttrium in Xenotime had been mistaken for a new element at the time of its discovery, hence it being named for the Greek for “vain” and “honor.” While exceptional crystals are uncommon, there are abundant localities at which Xenotime can be found occurring as an accessory mineral in rocks with alkali to granitic ...
