  • Glacial tectonics at the Kwintelooijen Sandpit, Rhenen, the Netherlands
  • Detailed structural field-work in a large exposure in a Saalian ice pushed ridge near Rhenen enabled the differentiation of several tectonic phases. Frontal thrusting was followed by subglacial seaing. Littology appears to be an important factor
  • in the movement of the thrust sheets. The basal layers of most thrust sheets are clays, loams and fine sands. Numerous normal faults are interpreted as relaxation structures developed after the main deformation phase.
