Abstract
Sand laminae interbedded with thicker pelitic sediments in the uplifted post-glacial succession near Outardes Falls, Quebec, are interpreted as storm deposits. The sands were put into suspension by strong wave action in the coastal zone and transported offshore. Shallow-water benthos were also carried offshore and deposited with the sand. Their presence indicates the coast was ice-free at this time. In places, the pelitic units with sand laminae are confined to bathymetric lows, suggesting that they may have been transported by low-density turbidity currents. The transition to this type of flow may have been aided by the presence of high subaqueous slopes and high concentrations of suspended fine sediments.
