Active olivine quarry, operated by Sibelco (earlier North Cape Minerals, and before that, originally, AS Olivin), producing ca. 2 million tonnes a year (1990) with reserves for more than 400 years, situated in the Almklovdalen peridotite massif.
Located in Almklovdalen, a few km from the village of Åheim.

The main rocks are dunite, garnet-peridotite and olivine-websterite.
