A sedimentation pattern in Anglian marginal meltwater channels from Suffolk, England

Authors


ABSTRACT

Several infilled glacial meltwater channels of Anglian age are described from SE Suffolk, U.K. These channels are up to 4km long, 150m wide and 8m deep. They possess a consistent pattern of infill comprising glacifluvial sands and gravels overlain by subglacial water-lain fine sands and silts; these pass conformably upwards through thinly interstratified tills and sands into basal tills. The channels were formed at the ice-margin. Their sedimentary infill indicates overriding by the ice-sheet and subsequent subglacial deposition.
