Preglacial weathering and landform evolution in Fennoscandia
The historical approach to geomorphology seems to be useful in the study of bedrock geomorphology on the Fennoscandian craton. A field meeting on the theme preglacial weathering and landform evolution was held in southern Sweden, May 16-20, 1988
Northeast Scotland is an area exhibiting selective erosion by Quaternary ice sheets. In this area both glacial and preglaciallandforms exist in close proximity. The depths of erosion which this modification represents are calculated
on the assumption of various depths of preglacial weathering. The aim of this paper is therefore to calculate the depth and rate of Quaternary erosion across northeast Scotland using geomorphological reconstruction.
The Cairngorm massif in NE Scotland is an excellent example of a preglacial upland landscape formed in granite. Glacial erosion in the mountains has been largely confined to valleys and corries and so has acted to dissect a pre-existing upland
. Intervening areas of the massif experienced negligible glacial erosion due to protective covers of cold-based ice and preserve a wide range of pre-glacial and non-glacial landforms and regolith. The cliffs that sharply demarcate the edges of glacial valleys
and corries allow the main pre-glacial landforms to be easily identified. The former shape of pre-glacial valleys and valley heads can then be reconstructed by extrapolation of contours to provide a model of the pre-glacial relief of the Cairngorms
A hypothesis is presented here of the landscape evolution of southeast Australia which brings together evidence of landforms, tectonics, drainage patterns and sedimentary basins to make a consistent picture. The sedimentary record of the basins

In this paper the terminology used in long-term geomorphology is evaluated. Long-term geomorphology is the study of landforms that are mostly pre-Quaternary, Cenozoic, Mesozoic or even Palaeozoic age. Many terms have been introduced to name the long
-term scale landforms that persist to the present. The definitions of many of these terms are ambiguous, have changed over time, and their use and meaning is consequently often unclear. An attempt is made to clarify definitions. Long-term geomorphology
in the respect that pre-Quaternary landforms were repeatedly covered by Quaternary ice sheets but often survived with different degrees of glacial modification.
This article introduces an analysis of two examples of cryogenic landforms - a rock glacier and a protalus rampart in the high-mountain zone of the Tatra Mountains. Field geomorphological research and airphoto interpretation helped
processes during the last glaciation. The most spectacular protalus ramparts have been recognised in areas representing remnants of the preglacial rather that the glaciated Tatra landscape (i. e. Liptovské kopy). The characteristics of these forms
it accumulates over sedimentary or weathered materials, therefore geomorphological heritage is a key factor in nival erosion. To test this hypothesis, the AA. identified the landforms in the study area and determined their relative ages by weathering
and lichenometry, differentiating between preglacial, glacial (Recent Pleistocene) and postglacial (Holocene) forms.
structural patterns. But their aim is rather to show the place of various glacial and periglacial forms in the landscapes among inherited preglaciallandforms strongly influenced by differential physico-chemical weathering, and more or less modified
main valleys. In the montane areas, RSF is strongly associated with vestiges of preglacial summit surfaces, confirming that plateau ridges are less stable than sharpened crests and horns. RSF is contributing significantly to the progressive destruction
The major landform regions in Landforms and landform evolution in West Germany.
On the basis of the morphostructural pattern, of the existing landform associations and of their morphogenetic development, the areas of the Federal Republic of Germany can be subdivided into five major landform regions : the North German Lowlands
Homoclinal ridges in Lower Saxony in Landforms and landform evolution in West Germany.
Recent investigations of structure-controlled landforms such as homoclinal ridges agree that, in general, these landforms are transitional stages within a landform development sequence that includes valley deepening, valley widening, pediment
