CLASSIFICATION OF KAME FORMS IN THE LIGHT OF TYPES AND OF DYNAMIC STAGES OF DEGLACIATIONSummaryThe article was prepared on the basis of the materials gathered by the geological crew of the Department of Lowland Geological Surveys, Geological Institute. A possibility of classifying kames was analysed, and a classification was presented for discussion. The dependence of kame forms upon the type and stage of deglaciation within the Lowland area and the forelands of the Świętokrzyskie Mountains and the Lublin Upland was considered, too. The examples presented in Fig. 1 come from the area of the maximum extent of the Middle-Polish (Riss) Glaciation, and from the areas covered with the inland ice of the Mazovian-Podlasie and North-Mazovian Stages that belong to this glaciation, as well as from the areas of the North Polish (Würm) Glaciation. Kames are considered here to be one of numerous relief types found to occur within the areas of the continental glaciations. The origin of these forms is related to the deglaciation periods. The following is the author’s definition of the kame forms: positive (convex) forms of relief, formed at the contact with the inactive or dead ice, built up of the material melted out of an inland ice, and laid down in closed basins. The kame forms are subdivided (Table 1), according to their position in relation to the inland ice sheet, into external (group I) and internal (group II) ones. The external forms developed at the contact with the inland ice margin on the one side, and with the slope of the non-glaciated area, on the other, e.g. external kame terraces (Fig. 2). The internal forms, in turn, were produced within the ice sheet under various conditions and to various degree of deglaciation. The internal kame forms are subdivided into the following groups: IIa - crevasse forms, IIb – melted-ice lake forms, IIc - englacial melting forms. Group IIa - developed during the initial periods of the inland ice destruction, in a zone situated close to the inland ice front. Here were produced ...
