The Høydalen locality consists of 2 separate amazonite pegmatite dikes, which are situated a few hundred meters apart. The pegmatites are hosted in a Precambrian metamorphosed gabbroic rock. Both pegmatite dikes have been worked as 2 different quarries; the upper and lower quarries. Lepidolite was mined here in the period 1941-43. Occasional blasting during the years has revealed several mineral species. It is the type locality of tveitite-(Y).

For a period the quarries were opened as a touristic collecting site with an entrance fee. The quarries are now abandoned. Collecting at dumps is not allowed without permission from the landowner!

Note to the mineralist:
A study of the purple and pink micas from Høydalen, has shown that
=> the very coarse grained mica varies between polylithionite and trilithionite,
=> the coarse grained purple mica can be classified as polylithionite
=> and the medium grained purple mica consist of intergrown ferroan muscovite and polylithionite (Rosing-Schow et al. 2017).
