AbstractForty kilometres of Huntec high resolution seismic profiles and f ow· piston cores have been studied from Kaipokok Bay, Labrador. Sedimentary and acoustic facies have been correlated. Proglacial gravels, sands and muds fill basin floors, generally resting on bedrock but locally on till. These are overlain by more widespread proglacial muds that drape over topographic highs. Small scale cyclic sedimentation of proglacial sands and muds may be a result of shifting of stream discharge points, either beneath the edge of a floating ice shelf, or· on a subaerial outwash delta. Flocculation leads to mineralogic segegation of illite in proximal environments and non-clay rock flour in distal environments. Late Holocene muds rest with an erosional unconformity on the proglacial sediments. They have accumulated as marine energy has been increasingly damped at the sill as sea level has fallen.
