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.
Vågenes
On Vågenes, on one of the prominences out toward Eitrevågen, one finds garnets in anorthosite. The garnets are both older, and not least bigger, than average.
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.
Urangsvågen-Rubbestadneset
In 1868 the first stone workers came to Rubbestadneset to take out the granite for the Skoltegrunns Pier, predecessor of the Skoltegrunns wharf in Bergen. Later granite was also taken out from the area, around Innværs Fjord and UransvågenN. The activity probably peaked around 1900, with over 40 men at work. 15 years later, it was finished.
Ulven
In the region of Ulven phyllite occurs with Hordaland's youngest fossils, and a beautiful quartz conglomerate. The phyllite and conglomerate got squeezed into the bottom of an ancient oceanic crust, made of gabbro and greenstone, in the heart of the Caledonide mountain chain.
Ulvanosa
Some mountains have rounded shapes, while others have steep slopes and sharp edges. Ulvanosa (1246 mos.) has both. The forms reflect the type of bedrock below, and the forces that were in effect when they were formed.
Sålesnes
Jondal has one of the country’s oldest slate quarries. Roof tiles have been extracted here since the end of the 1700s, but the quarry is much older. Kvernurdi is mentioned in a diploma in 1421, when Bård Sigurdsson at Torsnes became the owner through a settlement. Already then it must have been customary to cut millstones here.
