AbstractQuaternary sediments comprise five main units based on their acoustic character on high-resolution seismic profiles and sample data. These comprise ice-contact sediments, glaciomarine sequences, postglacial muds, postglacial sands and gravels, and locally in Eastern basin an acoustically unstratified unit of undetermined ice-contact or debris-flow origin. Sediment deposits, with the exception of some of the ice-contact sequences, are thickest and most complete in the basinal areas in Hudson Strait and Ungava Bay. These deposits are the main source of information regarding changing conditions, depositional and paleoceanographic environments, and chronologies in the marine areas of this region from late glacial time, through deglaciation, to more modern time. Information obtained relating to ice-margin positions, glacial-marine interactions, environments, and radiocarbon dates from fauna in cores provide a basis for correlations with the record of events in adjacent terrestrial and marine areas. In this paper the sediments, stratigraphic relationships, and late glacial-deglacial settings in each of the main basins and other relevant localities are illustrated and described, and associated chronological data are presented.
