New age constraints for the maximum extent of the last British–Irish Ice Sheet (NW sector)
Abstract This paper presents the first terrestrial age constraints from the outer continental shelf for the maximum extent of the NW sector of the last British–Irish Ice Sheet. Cosmogenic 10 Be ages from eight glacially transported boulders on the island of North Rona show that the Late Devensian (L...
