Ølve- Mining

All in all there are ten known copper mines and two iron mines on the Ølve peninsula. Geologically, the nine mines on Varaldsøy Island also should be figured in. The industry began at Lilledal in 1642 wth the mining of iron ore. From Jernsmauget by Dyråsen, the iron ore was sent to the iron works in eastern Norway.

Lussand- geology

Hardangerfjorden kløyver Hordaland i to. Den etter måten rettlinja fjorden skjer seg liksom på skeive inn i landet. Ikkje som Sognefjorden og Nordfjord – dei krokar og buktar seg innover meir eller mindre vinkelrett på kysten. Hardangerfjordens utforming har røter 400 millionar år tilbake i tida, då den veike sona i fjellet, der isen seinare tok grådig for seg, vart danna. Denne sona stig på land ved Lussand.

Kvamskogen

The different bedrock types that got shoved in over Hordaland in Cambro-Silurian times still remain, layer by layer, almost like a cake. But at Kvamskogen the cake has been turned upside down.

Vesoldo

Folds are to be found everywhere in the remains of the Caledonian mountain chain. Some were formed during the collision with Greenland, others stem from the time when the mountain chain collapsed. Few can compare with the giant fold that remains in the mountain area around Tørvikenuten, Vesoldo and Hellefjellet.
