| Abstract: | Lodgement till and flow till are depositcd in quite different environments. In Weichselian depmits, they can be distinguishcd by the setting of the sediments, the fabric, geotechnical characters, and the morphological appearance. These indications support each other. Of the outlined methods, the morphological is the most convenient in practice. Since flow till normally exists together with meltwater sediments it is suggested that systematic morphological mapping will be time-saving and most profitable for the prospecting of economically important clay, sand, and gravel deposits. |
