Rock fall protection

"In terms of geology, Norway is part of the Baltic shield, which ranges from Sweden to Finland and ultimately Russia. The oldest rocks in Norway are 3.5 billion years old. In the South and West of the country, there is the south-western gneiss province. Its rocks are 1.7 billion years old, and in the course of the gothic orogenesis, granite rocks intruded into these. In the western part of Norway, following the shoreline, we have the Caledonides; a mountain range formed 444 to 416 million years ago. It includes late Proterozoic and Silurian sedimentary rocks and meta-vulcanites deposited in the Lapetus Ocean, which preceded the Atlantic Ocean as we know it. Today, these rocks come in the form of paragneiss, different schists and green rocks."
