Influence of temperature conditions in formation of end moraines in Fennoscandia and Svalbard
In the Finnmark region of northern Norway, end from Younger Drays and earlier periods appear as irregular mounds and ridges in a broad zone with a distinct distal margin. These moraines are similar in shape to end moraines formed in Svalbard today by melting of ice‐cored moraines in front of subpola...

| Summary: | In the Finnmark region of northern Norway, end from Younger Drays and earlier periods appear as irregular mounds and ridges in a broad zone with a distinct distal margin. These moraines are similar in shape to end moraines formed in Svalbard today by melting of ice‐cored moraines in front of subpolar glaciers under permafrost conditions. The end moraines in Finnmark were mkost likely formed in the same way in a permafrost climate during deglaciation. This might also be the case for moraines in the southernmost parts of Fennoscandia, in Denmark and southernmost Sweden. Cold‐based ice during deglaciation in central parts of Fennoscandia is due to climatic conditions tens of thousands of years earlier. The period with climatic improvement after the Weicheselian maximum was too short to have any influence on the thermal conditions at the base of the ice‐cap in the central areas. |
