Abstract
Resolution and Hatton basins lie on the continental shelf northeast of Resolution Island, and east of the sill at the entrance to Hudson Strait, respectively. The basins are bordered shoreward and in part underlain by thick multiple ice-contact sequences deposited in the lee of higher standing Precambrian rocks northeast of Resolution Island and of the sill at the entrance to Hudson Strait west of Hatton basin. Glaciomarine sediments overlie ice-contact sediments in the basins and intertongue with, or appear laterally transitional to, the uppermost of the multiple ice-contact sequences. Sediments in both basins were deposited from ice originating in Hudson Strait. Cores in glaciomarine sediments in Resolution basin yielded basal dates greater than 20 ka BP, and higher in the section indicate a subtle change in sediment character coincident with dates that just slightly postdate Heinrich event H-1 (ca. 14.5 ka BP), and possibly may relate to that event. Deglaciation occurred 13-12 ka BP and was followed between 11 ka BP and 10 ka BP by a major ice advance from south to north across outer Hudson Strait and the inner shelf. In Hatton basin cores show a relatively similar chronological pattern with a 13 ka BP date near the shelf break and farther west dates of 11.3 ka BP, younging upsection to 9-8 ka BP.
