Abstract
The subject matter included within Cainozoic glaciations and crustal movements of the Arctic is immense both in terms of the area covered and the period of time under review. These practical difficulties are heightened and aggravated by an overall sparsity of data and widely divergent theories, not to mention the fact that approximately half the land area lies in the USSR and much Russian literature is not readily accessible to Western scientists. With these provisos the scope of this chapter can be briefly outlined. The story does not open at the Pliocene/Pleistocene boundary because it is becoming increasingly evident that glaciation in many areas preceded this time line. Consequently the first concern is with the tectonic events of the Tertiary and the arrangement of the landmasses relative to each other and to the position of the rotational pole. Miocene glaciations are then discussed together with a consideration of the causes of theglacial/interglacial periodicities that characterize the Quaternary proper. The actual number and timing of these events is then taken up largely through the detailed stratigraphic records that have been deciphered in Alaska and Siberia and from ocean cores. A more detailed treatment of events is possible for the last glacial stage - the Wisconsin or Wurm. Glacials and interglacials involve a mass transfer of ice/water in response to the build-up and removal of loads. The response of the arctic regions to glacio-isostatic and eustatic crustal movements are elaborated and used to locate the main centres of glaciation in the region.
