Several feldspar quarries in a granite pegmatite located 5km SE of Evje center and 1 km N of Lauvland.
Bjørlykke locality nr 107.
Note on the mineral list:
The mineral Schetelig (1931) called thalenite was later shown to be a beta-phase of Y2Si2O7 with a thortveitite structure (Neumann 1985). It is identical with the mineral described as keiviite-(Y) from Kola, Russia by Voloshin et al. (1983).
A re-examination of original material of tombarthite-(Y), which was described from Høgetveit, shows that all samples are heterogeneous, and hence not constituted by a single mineral. It was thus descredited by IMA in 2016 (Proposal 16-K).
NOTE RW 2021:
It is actually more correct to say "Høgetveit Quarries", since there are several separate quarries located in this pegmatite.
