Espevik
220 million years ago, glowing hot molten rock masses intruded into fractures in the earth's crust in the outer parts of Hordaland. Some of these are believed to have reached the surface and formed lava flows, which since have been eroded away by wind and weather. But, most of these flows solidified into diabase sills before they got to the surface.
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.
