On the origin and flow behavior of submarine slides on deep-sea fans along the Norwegian-Barents Sea continental margin (original) (raw)

Debris lobes with characteristic lengths, widths, and thickness of 30-200 km, 2-10 km, and 10-50 m, respectively, represent the main building blocks of deep-sea fans along the Norwegian-Barents Sea continental margin. Their formation is closely related to the input of clay-rich sediments to the upper continental slope by glaciers during periods of maximum ice advance. It is likely that slide release was a consequence of an instability arising from high sedimentation rates on the upper continental slope. The flow behavior of the debris lobes can be described by a Bingham flow model.
