'''Xenotime-(Gd)''' is athe [[Xenotimegadolinium]] speciesendpoint of [[Xenotime]] with the ideal formula {{chem2|Gd(PO4)}},. It is being one of the few known [[gadolinium]]-dominant [[rare earth mineral]]s.

==Discovery==

It was first described in 2024 from on gadolinium rich [[xenotime-(Y)]] from [[Prakovce]] in Slovakia. Besides [[yttrium]], the examined type material bore further [[rare earth elements]] such as [[dysprosium]], [[samarium]] and [[terbium]]. <ref name=Ondrejka2024>{{cite journal |vauthors=Ondrejka M, Bacik P, Majzlan J, Uher P, Ferenc S, Mikus T, Stevko M, Caplovicova M, Milovska S, Molnarova A, Rössler C, Matthes C |date=2024-11-14 |title=Xenotime-(Gd), a new Gd-dominant mineral of the xenotime group from the Zimná Voda REE–U–Au quartz vein, Prakovce, Western Carpathians, Slovakia |url=https://www.cambridge.org/core/journals/mineralogical-magazine/article/xenotimegd-a-new-gddominant-mineral-of-the-xenotime-group-from-the-zimna-voda-reeuau-quartz-vein-prakovce-western-carpathians-slovakia/BAE272E641CD070077D393E07047A620 |journal=Mineralogical Magazine |volume=88 |issue=5 |pages=613-622 |doi=10.1180/mgm.2024.62 |pmc= |pmid= |access-date=2024-12-27}}</ref>
