abstract

Cross-bedding in the Pyramiden, Schumacher and H鰃fonna Formations has a clear preferred orientation with a relatively small variability in azimuth, indicating continual uplift of the provenance area. In the case of the Tindeklypa Formation volcanic activity caused frequent shifts in current direction as a result of which cross-bedding in this formation shows no clear preferred orientation. The results, especially in the upper part of the Schumacher Formation and the three members of the H鰃fonna Formation, indicate a clockwise movement of the provenance area relative to穞he Ahlmannryggen during deposition.
