| Definitionskos:definition | A sedimentary depocentre formed at the grounding zone of an ice sheet/ice-shelf system, formed of dipping diamicton beds overlain by horizontal sheets of diamicton, mainly subglacial till. Till emerging from beneath the glacier along a line-source is redistributed by subaqueous debris flows, producing diamicton beds that dip away from the margin. GZWs are usually asymmetrical in long-profile, steeper in the ice-distal direction (Excerpt from Bell et al. 2016, adapted from Bell et al. 1997. In: Dowdeswell et al., 2016). |
