  • The reversed remanent magnetic polarity of glacial and glaciolacustrine sediments at Antes Fort allows for revision of the chronology of pre-Wisconsinan glaciation in central Pennsylvania.
  • Glacial valley cross-profile development: the influence of in situ rock stress and rock mass strength, with examples from the Southern Alps, New Zealand
  • Special issue. Glacial geomorphology: process and form development
  • Glacial erosion ; Glacial valley ; Model ; Mountain ; New Zealand ; Shear stress ; Slope gradient ; South Island ; Structural stability ; Tectonics ; Valley
  • Southern Alps. Finally, a conceptual model is proposed linking the factors involved in controlling glacial valley cross-profile development. Such a model is required for realistic modelling of valley profile evolution.
  • The potential influence of in situ rock stress regimes, rock mass strength of the slope rock, and subaerial processes are considered here in some simple models of glacial trough cross-profiles from the vicinity of the main divide of the New Zealand

  • Geomorphometry ; Glacial erosion ; Glacial features ; Model ; New Zealand ; Rocks ; South Island ; Valley
  • The purpose of this paper is to examine the model developed by Hirano and Aniya (1988, 1989, 1990) for the development of the glacial valley cross-profile, and to offer an alternative model using rock mass strength (RMS) and morphometric data
  • Glacial geomorphology of Bonney drift, Taylor valley, Antarctica
  • Glacial and paleoclimatic history of the Ross ice drainage system of Antarctica. Special issue
  • Aerial photography ; Antarctica ; Cold area ; Geomorphology ; Glacial features ; Grain size distribution ; Mass movement ; Moraine ; Quaternary ; Sedimentology
  • The aim of this paper is to document the response of the East Antarctic Ice Sheet (EAIS) near the Dry Valleys to the excess warmth of the last interglaciation by establishing the behavior of Taylor Glacier. The AA. present a model for the deposition
  • by Taylor Glacier of Bonney drift in central Taylor Valley. Bonney drift is important because it records the penultimate advance of Taylor Glacier through central and lower Taylor Valley.
  • Rate of glacial valley deepening during the Late Quaternary in Assynt, Scotland
  • Cave ; Dating ; Erosion cycle ; Erosion rate ; Glacial erosion ; Glacial features ; Glacial valley ; Interglacial ; Isotope analysis ; Quaternary ; Scotland ; United Kingdom ; Uranium
  • A dated landscape history of the Allt nan Uamh valley in the Assynt area is constructed, spanning the last 300 ka, using geomorphological analysis, U-series speleothem dating, and existing cave surveys. The mean rate of valley deepening is estimated
  • to lie between 47 and 68 m per glacial/interglacial cycle of 100 ka. This, combined with an estimated duration of glaciation, implies glacial erosion rates in agreement with modern process measurements.
  • Development of glacial-valley cross sections under conditions of spatially variable resistance to erosion
  • Special issue. Glacial geomorphology: process and form development
  • Erodibility ; Glacial erosion ; Glacial valley ; Lithology ; Model ; New Zealand ; Slope gradient ; Spatial variation ; Valley
  • A simulation model that examines the development of valley cross-profiles as a result of glacial erosion has been constructed by placing a finite-element model for ice flow within an iterative program that modifies channel cross-section form
  • on the basis of an erosion equation. The simulation model has previously been used to examine how different flow laws, erosion laws and ice discharge histories affect medium-scale landform development. This allows to better understand the development of glacial
  • Rock strength and development of glacial valley morphology in the Scottish Highlands and northwest Iceland
  • Geomorphogenesis ; Glacial erosion ; Glacial valley ; Highland ; Ice sheet ; Iceland ; Lithology ; Model ; Rock mechanics ; Scotland ; United Kingdom ; Valley
  • Using data from the Scottish Highlands and northwest Iceland, this study indicates that bedrock strength properties are an important control on the morphology of glacial valleys. Results indicate that on closely jointed metasedimentary bedrock
  • of low rock mass strength, broad U-shaped valleys are developed, whilst steeper sided, narrower cross-profiles have been developed on igneous bedrock of high rock mass strength. Findings suggest it is the interplay of the mass strength of the subglacial
  • bedrock and he dynamic properties of the eroding glacier that control valley morphological development.

  • Polynomial and power functions for glacial valley cross-section morphology
  • California ; Geomorphometry ; Glacial features ; Glacial valley ; Model ; Mountain ; Quaternary ; Regression analysis ; Sierra Nevada ; Slope profile ; United States of America
  • An empirical evaluation of glacial trough cross-section shape is performed on seven vertical cross-sections in three Sierra Nevada valleys glaciated during the late Quaternary. Therefore, this study utilizes a datum at the upper valley wall where
  • lateral moraines, trim lines or erratics can provide a clear limit to the glacial extent based on field evidence. This datum is referenced to coordinates of zero in the horizontal direction and elevation above sea level in the vertical dimension.

  • Antarctica ; Cenozoic ; Geochronology ; Glacial features ; Ice sheet ; Moraine ; Palaeoclimate ; Stratigraphy ; Volcanic ash
  • The aim of this paper is to produce a detailed geologic record of late Cenozoic glacial and non-glacial sedimentation and paleoclimate change. The Quatermain Mountains are ideal for recording ice-sheet fluctuations and paleoclimate change because
  • they are adjacent to the East Antarctic Ice Sheet and exhibit a suite of glacial erosional features, semi-arid landforms, and widespread drift and colluvium.

  • Special issue. Glacial geomorphology: process and form development
  • Colorado ; Deglaciation ; Glacial valley ; Glacier margin ; Hypsometry ; Model ; Mountain ; Pleistocene ; Quaternary ; Topography ; United States of America
  • The A. uses the location of stagnant ice deposits in many San Juan valleys, Colorado, to test how valley hypsometry and topographic obstructions influence the type of margin present during valley glacier retreat.
  • 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
  • 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
  • . 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.
