  • are inferred from the geological evidence : rapid, episodic and slow. They indicate that Antarctic palaeo-ice-streams did not respond uniformly to external forcing at the end of the last glacial cycle. Rather, their diachronous retreat reflects the dominance
  • This paper is aimed at exploring whether there is a simple, reproducible relationship between fabric development and shear-strain magnitude that could be used to help test the bed-deformation model using the geologic record. Four basal tills
  • of north-eastern Canada formerly covered by the Laurentide Ice Sheet. Four different cases are considered and analysed in a geographical information system (GIS) environment with full integration of ancillary topographical and geological data. The AA
