| Abstract: | On the basis of the numerical solution of Stefan-like boundary-value problems the simplest palaeoclimatic and geothermal models are analyzed. Typical histories of freezing isotherms, temperature and heat flow changes are calculated taking into account the effects of accumulation and denudation. The results show that the geothermal field demonstrates a better ability to recollect palaeocryologic environment when the phase transitions of subsurface water are involved. However, the geothermal traces of past cryogenic events in Northern and Central Europe before the middle of the Pleistocene could hardly remain up to the present day. |
