Abstract

The advancement of the lower parts of the glacier-foot into and across the sands of the foreland implies the following genesis of push-moraines: Shoving off a place of sand, folding it and pushing it over the foreland at average rates of up to 7,2 mm/h, according to the investigations in the summer of 1983. At a certain stage of the folding process, new folds begin to develop in front of the old, and the old folds are shifted onto the backslope of the folds in front of them until they are completely united. In this way, "pile-moraines" arise, which become higher and higher. They include two or more folds declining towards the glacier. Systems of small moraines presumably of the same genesis occur on old moraine areas in front of the Kotlujokull. (L'A.).
