Summary

Occurrences of penecontemporaneous folds of varying style and amplitude are described from low-metamorphic flysch sediments from an area in the Central Norwegian Caledonides. A short discussion of the mode of formation of these folds is presented, and from geometrical considerations it is suggested that, in several cases, both foundering and slumping have contributed to the overall deformation. The significance of the presence of these structures in the stratigraphical sequence is outlined, and the inherent danger of their possible misrepresentation as tectonic folds in higher metamorphic areas is briefly discussed.
