Varaldsøy- mining
There is still a lot of ore in the abandoned mines on Varaldsøy Island. If today's prices and availability of ore continue, it is doubtful whether the mines will resume operation. But, the pyrite is there, if the market should return. On Varaldsøy Island one finds at least nine mines and prospect pits, that for the most part date back to the latter part of the 1800s.
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.
Trail toward Kyrkjedøri
Roughly 550 million years ago, what is now Finse lay at the bottom of the sea - the remains of mud and clay that were deposited in this sea have ended up on the roofs of Norway. Also the thrust sheet from the continental collision has found its way to Finse, after a several hundred kilometre-long, trek through the mountains, that took several tens of millions of years to complete.
Vatlestraumen
There are coal bits hidden in the sand under Vatlestraumen. These remains from a geological layer from the Jurassic Period were discovered when the undersea Bjorøy Tunnel was built in 1994. Oil- and gas reservoirs in the Troll Field in the sea west of Hordaland are from the same time. It is, nonetheless, quite surprising to find bedrock from dinosaur time inside of the outer islands of western Norway. On the Scandinavian mainland north of Denmark, there are only a very few places where one f inds rock from this time in earth history.
Holmengrå
Holmengrå is the only place in Hordaland where we find traces of the abrasion that is supposed to have transformed Western Norway from a Himalaya-like high mountain landscape during the earth's Paleozoic Era, to a flat lowlands terrain during the Mezosoic Era. Just 400 million years ago, large and small stones plummeted down from the high mountains. Some of these stones became incorporated into the conglomerate bedrock on Holmengrå.
Litlandsvatnet
Large quantities of nickel ore have been mined from Litlandsvatnet, between Lonevågen and Hosanger. The discovery was made in 1875. During the period of operation from 1882 to 1945, 4170 tonnes of pure nickel were extracted from 462 000 tonnes of ore, a large production by Norwegian standards.
Lykling- gold
During the summer of 1979 a rock was found at Lykling in Bømlo that contained 450 grams of gold, and at the end of the 1980s a great many gold samples were laid out for sale. In the old mining area there are still gold miners hunting for the precious metal. But, the big adventure stories are a thing of the past.
Litlabø
The first finds of pyrite at Litlabø in Stord came to light in 1864. Forty years later sulphuric ore was mined from an open mine. From 1874 to 1880 it was used for dynamite production. That came to a sudden end when the factory exploded and three people died.
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.
Sandviksfjellet
On Sandviksfjellet there are old boulders that have been made into mountains. The stones have been stretched out or squeezed together between huge slabs of rock, during slow, but powerfulprocesses of transport. This conglomerate shows, in quite a special way, the enormous powers that were active during the collision between Norway and Greenland over 400 million years ago.
