  • Glacial erosional landforms : origins and significance for palaeoglaciology
  • Bibliography ; Channel ; Cirque ; Geomorphology ; Glacial erosion ; Glacial features ; Ice sheet ; Meltwater ; Palaeogeography
  • The AA. review recent developments in the understanding of the processes and landforms of glacial erosion and consider their value in palaeoglaciology. They surmize that glacial erosional landforms offer insight into former glaciological conditions
  • at both the landform- and landscape-scale within palaeoglaciology. They conclude that landforms of glacial erosion are of great value in ice mass reconstruction and speculate that these landforms will achieve greater recognition within palaeoglaciology

  • Glacial and periglacial processes, their landforms, influences of cryogenic destruction, and repeated freezing and thawing effects in rocks and their weathered mantle are described. Main features and dynamics of present-day and former glacial
  • and periglacial environments are presented as an evidence of significant global change of various landscapes in the Quaternary epoch. Knowledge of glacial and periglacial processes and landforms provides a background for understanding the present-day global change
  • Glacial geomorphology : modelling processes and landforms
  • Glacial erosion ; Glacial features ; Glacier ; Glaciology ; Global change ; Ice sheet;Ice cap;Inlandsis ; Modelling ; Numerical model
  • The first section of this paper provides a very brief overview of the main trends in Anglo-American glacial geomorphology from 1900 to the present. The A. then discusses more detail work on process modeling of glacial landform development, an area
  • which he considers to be one of the major research frontiers in glacial geomorphology. This provides a basis for exploring what research techniques and priorities in glacial geomorphology might be like in the twenty-first century.
  • The glacial topography in the area of the middle-lower reaches of the Yangtze river
  • The Quaternary glacial landforms, such as cirques, glacial troughs, rock drumlins and lateral moraines are discovered in the area of the middle-lower reaches of the Yangtze river. Based on the feature of glacial landforms and the data of analysis

  • Landforms in Skåne, South Sweden. Preglacial and glacial landforms analysed from two relief maps
  • Cenozoic ; Geomorphological map ; Geomorphology ; Glacial features ; Lithostratigraphy ; Quaternary ; Sweden
  • The purpose of this study is threefold, first to test the usefulness of detailed relief maps in geomorphic mapping, second to use information from the morphology to reconstruct the Tertiary landscape and to reveal the Late Glacial history
  • of the area, and third to evaluate the combination of past processes in the appearance of the present landforms.
  • Scottish Landform Examples: The Cairngorms – A Pre-glacial Upland Granite Landscape
  • Geomorphology ; Glacial erosion ; Granite ; Model ; Preglacial landform ; Scotland ; United Kingdom ; granite ; landforms ; pre-glacial glacial erosion
  • . 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
  • 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
  • . This relief model provides a basis for understanding the development of the landscape over timescales of many millions of years, including the role of geology, weathering, fluvial erosion and, lately, glacial erosion in shaping the relief.
  • Mega-scale glacial lineations and cross-cutting ice-flow landforms
  • Canada ; Cold area ; Drumlin ; Earth surface processes ; Glacial erosion ; Glacial features ; Glaciology ; Ice sheet;Ice cap;Inlandsis ; LANDSAT ; Northwest Territories ; Remote sensing
  • Landsat images reveal a previously unsuspected large-scale pattern of streamlining drift that is assumed to reflect former phases of ice flow. The ice-moulded landform assemblage is described and illustrated with reference to examples from Canada
  • . Possible modes of genesis of such landforms are discussed and their glaciological implications outlined.
  • Periglacial glacis (pediment) generations at the western margin of the Rhine Hessian Plateau in Landforms and landform evolution in West Germany.
  • The stratigraphical record and the morphological correlation to the Nahe terraces show that the latest glacis development took place during the Würm glacial and another during the Riss glacial. By analogy it was concluded that the older, higher
  • glacis remnants were formed during the earlier Pleistocene glacials. The western margin of the Rhine Hessian, Plateau provides, therefore, evidence that glacis and, in a wider sense, pediments did form during the Pleistocene glacials.
  • Rock weathering characteristics as relative-age indicators for glacial and post-glacial landforms on Marion Island
  • Geochronology ; Glacial features ; Postglacial ; Prince Edward Island ; Quaternary ; Relative dating ; South Africa ; Weathering
  • Rock weathering as relative-age indicators are tested on rock surfaces of generally known chronological sequence on Marion island in the sub-Antarctic. While the weathering characteristics could not establish any chronosequence in the relict glacial
  • rock surfaces the techniques can resolve relative ages in the primarily Holocene post-glacial rock surfaces. - (AJC)

  • Pre-glacial landform inheritance in a glaciated shield landscape
  • Arctic Region ; Digital elevation model ; Geographical information system ; Glacial erosion ; Glacial features ; Granite ; Northern Sweden ; Palaeosurface ; Shield ; Sweden
  • with the same sets of landforms and of similar relative relief, but with different degrees of glacial streamlining. Semi-quantitative estimates of glacial erosion on inselbergs and palaeosurfaces and in valleys are derived from estimated pre-glacial regolith
  • depths and from morphological evidence of glacial modification. Pre-glacial landform inheritance is shown to be here a major element in the development of landforms of glacial erosion.
  • The AA. seek to quantify glacial erosion in a low relief shield landscape in northern Sweden. They use GIS analyses of digital elevation models and field mapping of glacial erosion indicators to explore the geomorphology of 3 granite areas
  • Inherited landforms and glacial impact of different palaeosurfaces in southwest Sweden
  • Geomorphogenesis ; Glacial erosion ; Glacial features ; Glacial striation ; Granite ; Inherited features ; Palaeosurface ; Peneplain ; Roche moutonnée ; Sweden ; Vertical movement
  • Landforms are used as analytical tools to separate inherited features from the glacial impact on Precambrian basement rocks in southwest Sweden. The study covers 3 different palaeosurfaces, the sub-Cambrian peneplain with the character
  • of a pediplain, an uplifted and dissected part of the sub-Cambrian peneplain, and an etching surface presumably sub-Mesozoic. The surfaces were recently re-exposed, probably due to a Neogene upheaval with some pre-glacial reshaping. This study aims at evaluating
  • the qualitative and quantitative effects of glacial erosion in relation to exhumed palaeosurfaces and their reshaping due to deep weathering after re-exposure. Plane and convex bedrock forms are the focus of attention.
  • The glaciolacustrine landform-sediment assemblage at Heinabergsjοkull, Iceland
  • Glacial features ; Glacial lake ; Glaciolacustrine ; Iceland ; Lithostratigraphy ; Palaeogeography ; Pleistocene ; Sedimentary structure
  • Landform-sediment assemblages associated with two ice-dammed lakes, one active and one fossil, at Heinabergsjοkull in southeast Iceland are described. These data are vey important for the interpretation of Pleistocene ice-dammed lakes.
  • Mapping of glacial landforms from Seasat radar images
  • Glacial landforms in the drumlin drift belt of Ireland and the Alaska Range can be identified and mapped from Seasat synthetic-aperture radar (SAR) images. Because SAR is not affected by seasonal differences in solar illumination or by cloud cover
  • , it is particularly well suited for monitoring glacial movement. The disadvantage of distorted high-relief features on Seasat SAR images can be reduced in future SAR systems by modifying the radar illumination geometry.
