  • Geomorphological and geological investigations on closed topographic depressions and valley systems on the Drente plateau allow correlations to be made between the location of pingo remnants on the plateau and the Weichselian drainage pattern
  • . In general, the depth of the remnants varies between 2 and 7m, but locally the geological structure of outcropping sediments is responsible for the development of extremely deep pingo remnants, reaching a maximum of 17m. This figure gives a tentative estimate

  • by centripetal displacements. Accordingly, in large eroded impact structures, where in general only displaced blocks and megablocks can be observed, geological studies should be made on separate sectors, not on the whole structure as a unit (the sector principle
  • ). Geological observations in the Siljan ring structure are discussed from this point of view.
