Thalénite-(Y) from
Hundholmen, Narvik, Nordland, Norway


Locality type:Quarry
Classification
Species:Thalénite-(Y)
Formula:Y3Si3O10F
Comments:Vogt (1922) described thalénite-(Y) from Hundholmen. Later EMP analysis of thalénite-(Y) from Hundholmen has showed this to be a fluorthalénite-(Y) (Raade & Kristiansen 2009). But later in 2014 fluorthalénite-(Y) was descredited as a species by IMA (IMA 14-D), when Thalénite-(Y) was redefined as a F-dominant species with ideal composition Y3Si3O10F.
