The Oslo Fjord is a large Permian graben structure with an offset of more than 2000 m. The stratigraphic resolution based on lithology and fossils is high and allows a construction of a detailed map.
Tectonic deformation occurs on a minor scale with numerous folds and thrust-folds.
The deformational pattern is simple although the detailed mapping and presentation may be quite complicated. Each group of two or three students map their own area of about 0.5 km 2 . Each group will receive instruction in the field of approximately one hour per day. During the evening sessions the results of the daily effort are evaluated, maps and profiles are refined, and plans for the next day are made. Midway in the field course there is a one day excursion to important exposures of the Oslo Field.
