Late Devensian ice-sheet in the western Grampians, Scotland
A radial pattern of ice flow of the last ice-sheet in the largest source area of ice in the British Isles is demonstrated by the dispersal of indicator erratics and by patterns of striae, friction cracks and ice-moulded landforms.
Weichselian ice movement in South Norway and adjacent areas
Three main phases of ice-movement pattern in South Norway during the Weichselian are reconstructed. During phaseIII (possibly of Middle/Late Weichselian age) had an easterly situated ice divide. During phaseIV (Preboreal age) the ice divide had
moved back to the West and had partly fragmented into separate domes. The migration of the ice divide from West to East may be due to glacier surges, whilst the ice-divide migration from phaseIII to IV was probably a result of a general reduction in size
On the use of glacial striae for reconstruction of paleo-ice sheet flow patterns - with application to the Scandinavian ice sheet
The methods used to extract ice flow directions from striae data are discussed. The present paper is an attempt to highlight some crucial points and propose a practicable terminology. A stepwise analysis procedure for large-scale striae patterns
Ice-wedge casts in an early deglaciated area of southern Sweden
In the Laholm plain, NW Scania, an area that was the first part of Sweden to emerge from the Weichselian ice-sheet, three types of ice-wedge casts are observed. The wedges are discussed from a morphogenetic, morphostratigraphic and chronological
Striae and former ice-flow directions in Snowdonia, North Wales
The striation pattern reflects ice flow radiating from the general vicinity of Snowdon summit and the strong eastward component of flow contradicts the idea that the Welsh ice sheet overran the area.
Glacial ice-flows on the islands of Bornholm and Christianso, Denmark
This paper contains results from studies of ice flow directions on the islands of Bornholm and Christianso, Denmark, as indicated by striae and other marks of glacial erosion on the bedrock surface.
Maps are presented for the subglacial topography of Storglaciären, Isfallsglaciären and Rabots glaciär in northern Sweden. The maps are results of radio-echo soundings. Isfallsglaciären consists of one isolated basin above the ice fall uhereas
storglaciären is situated in a valley which is divided into three basins. No depressions were found in Rabots glaciär. The distribution with elevation was obtained for ice thickness, bedrock and ice surface areas, and ice volumes. Data for Storglaciären: area
A = 3.1 km, ice volume V = 306 10 m, average ice depth h = 99 m, maximum ice depth H = 250 m. Data for Isfallsglaciären: A = 1.3 km, V = 93 10 m, h = 72 m, ht = 220 m. Rabots glaciär: A = 4.1 km, V = 346 10 m, h = 84 m, ht = 175 m.
which in turn allow the interference of specific directions of ice flow. A dynamic model for the pattern of ice flow during the Wolstonian glaciation of eastern England is outlined. In this model North Sea ice is progressively replaced and deflected
southwest and south by the more powerful Vale of York ice. (from the A's abstract).
Ice-pushed Lower and Middle Pleistocene deposits near Rhenen (Kwintelooijen): sedimentary-structural and lithological/granulometrical investigations
In the Kwintelooijen sandpit, located in the inside of a large ice-pushed ridge, a number of thrust sheets are exposed which were formed by pushing inland ice during the Saalian glacial time. In these glaciotectonic units periglacial and fluvial
Fluvioglacial landforms and ice margin characteristics. An example from the Torneträsk area in northern Sweden
, sediment structure and setting in relation to the retreating ice margin. A reconstruction of the ice front characteristics was made from studies of the morphology and sediment structures of fluvioglacial deposits.
Reconstructions of the retreating margin of the inland ice during the last deglaciation have shown that calving bays or estuaries were frequently formed in subaquatic areas. Such more or less deep bays in the ice margin are indicated by the pattern
covered by prominent ice lobes. The moraines, which are long winding till ridges, oriented almost parallel to eskers, are located in areas covered by these lobated sections of the inland ice. It is suggested that the ridges are correlated to basal
Sediments of different lithological composition of a common feature, a relict system of thick syngenetic ice wedges, are called ice complexes . Three types of ice complex are distinguished in N Jakutia, with different topographic roles. They formed
The extent of some glaciers in Northern Iceland during the little ice age and the nature of recent deglaciation
Lichenometric studies from four glaciers in Northern Iceland are used to determine the dates of their Little Ice Age maxima. In all cases these date to the last half of the nineteenth century and probably marked the maximum Neoglacial extent
