Forkortet: The tract of land here treated is situated in Southern Norway between Sogne- fjord and Bøverdal, at 61\u00B030'N and at 3\u00B0W of Oslo. The rocks of the region form the following sections: 1. Archaean gneiss and granite (red lined on the map). 2. Phyllite, with quartz-schist and limestone (Cambrian and Silurian). 3. Gneissic rocks, highly metamorphosed and crushed. They consist for a great part of schistose modifications of the Jotun-gabbro. This section also con- tains crystalline schists of sedimentary origin; but they are so interwoven with schistose igneous rocks that they can not be separated on the map. 4. The uppermost section consist of a series of gabbro rocks which form the mountains Jotunfjeld (brown on the map). The Archaean was here folded and denuded, before the Cambrian was depositet, and later came the great uplift and folding during the Devonian age. The surface between the Archaean and the Cambrian was then much deformed. Through the folding a deep syncline was impressed, its bottom ruptured, and through the rents igneous rocks were pressed forth. By this procedure overthrusts were also brought about, mainly in a southeasterly direction, perpendicular to the axis of the syncline.
