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.

Minor accessory mineral in both acidic and alkalic igneous rocks and their pegmatites. IMA Status: Valid Species (Pre-IMA) 1832 : Locality: Hidra (Hitterø), Flekkefjord, Vest-Agder, Norway Link to MinDat.org Location Data. Name Origin: From the Greek xenos - "foreign" and time - "honor." Name Pronunciation: Xenotime-(Y) Synonym: ICSD 79754

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.

Xenotime is a yttrium phosphate mineral that contains a high rare earth oxide content, particularly heavy rare earth elements. It is often found alongside monazite and is a significant source of heavy rare earth elements.

Xenotime describes a group of several closely related phosphates, arsenates, and vanadates composed of rare earth elements. The term is generally used to describe the most common member of the group, Xenotime- (Y), which is the yttrium phosphate end member of this series.

Xenotime, widely distributed phosphate mineral, yttrium phosphate (YPO4), though large proportions of erbium commonly replace yttrium), that occurs as brown, glassy crystals, crystal aggregates, or rosettes in igneous rocks and associated pegmatites, in quartzose and micaceous gneiss, and commonly

Dec 9, 2024 · Xenotime, a unique mineral, is a source of rare earth elements like yttrium and has various uses in technology, medicine, and industry. It's found in countries like Brazil, Norway, and the United States.

Xenotime is a very rare mineral, it is an accessory mineral in some alkaline granite, syenite and similar siliceous rocks. Optical properties: • Color: Colorless or pale yellow-brown • Form: Euhedral stubby bipyramidal crystals • Relief: Moderate • …

Sep 15, 2008 · Xenotime is a tetragonal mineral (space group I4 1 /amd) with a zircon-type structure. It is characterised by an ideal formula of AT O 4 where A represents yttrium (Y 3+ ) and T a tetrahedrally coordinated atom of phosphorous (P).

This simple specimen consists of a single crystal of Xenotime, a rather rare yttrium mineral. It has reasonably good tetragonal prismatic form with well-defined edges and faces, and shows a bright, almost vitreous luster.
