摘要：

The Kronhede sandur forms part of a ca. 1500 km(2) Late Pleistocene outwash system located in western Jylland, Denmark. A sedimentological study was carried out in the proximal part of the sandur. The sediments were deposited during progradation of the glacier as shown by a general coarsening-upward lithology, terminating with a jokulhlaup episode characterized by large compound dune migration and slack-water draping. Mapping of a more than 200 m long well exposed pitwall and ground-penetrating radar measurements in a 50 X 200 m grid along the pitwall made it possible to outline the three-dimensional geometry of the jokulhlaup deposit, forming the top part of the succession. The paper describes the sedimentology of the sandur deposits and the application of the ground-penetrating radar technique to sedimentary architecture studies.
