| Abstract: | Thin-bedded debris flow deposits are an important constituent of the marine Quaternary, sequence in NW Baffin Bay, covering about 30,000 km2 of sea floor. Individual debris flows traveled over a slope as low as 0.4° and a distance of several hundred kilometers. Some debris flows have generated turbidity currents. Debris flow deposits observed in the cores displayed distinctive downslope trends in grain size, bed thickness, and sorting, and showed variations in structures and sequences of sedimentary structures with poorly to moderately well-developed gravel fabric, showing the long axes of clasts aligned nearly parallel to the bedding plane. |
