Abstract

Turbidite beds in the Silurian turbidite sequence, North Greenland, show soft sediment deformation struc­tures suggesting that the structureless (in respect of traction structures) sandstones divisions of the turbidi­tes were deposited by direct suspension sedimentation from high-density flows. The deposits may have re­sulted from multiple successive depositional events within the same turbidity flow. Reworking and shear- ing of the newly formed loosely packed high-density suspension deposits caused by the still moving flow above create secondary soft sediment deformation structures which may be used as current indicators if other structures are absent (e.g. flute casts).
