Glacio-fluvial sands are deposited when ice advances or recedes, which consist of coarse sands from the melting of the advancing glacier (Vorschüttsand) and finer sands deposited during the ice recession (Nachschüttsand); these are usually seperated by a ground moraine. Sand sediments from the ice advance, a ground moraine, and sand from the ice recession form a glacial cycle. If there is no ground moraine, a genetical classification of the sediments into the phases of advance...
