| Summary: | The Caledonian mountain chain in Norway: One of the most important and interesting problems in Scandinavian geology is the structure of the Caledonian Mountain chain, which runs through the country from Hardanger to the North Cape. A great part of the mountain chain lies on both sides of the border between Norway and Sweden. The chain extends southwest of the British isles, from whence its name is derived. The geology of mountain chains has developed enormously since the turn of the century when the author started his geological studies. Scandinavian geologists have rendered many contributions to the description of the Caledonides of Norway and Sweden, but many problems still remain. As our mountain chain is highly eroded it is important to make the comparative studies of other mountain chains, especially of the Alpine chain, which belongs to the Mesozoic and Tertiary periods, while the Caledonian chain rose if the first part of Paleozoicum and the Varizian chain in the younger part of Paleozoicum. The ideas of geosynclines, overthrusts, granitization etc. are now generally accepted. It has also become clear that mountain chains commonly have a symmetric structure. 35555
