Stadials and interstadials during the Weichsel glackiation on Finnmarksvidda, northern Norway

Till beds and waterlain sediments from at least 3 stadials and 2 interstadials during the Weichsel glaciation are recorded on Finnmarksvidda. The oldest, possibly Weichselian, ice‐free period recorded on Finnmarksvidda is represented in one river section and is preliminary named the Vuolgamasjåkka t...

Description
Summary:Till beds and waterlain sediments from at least 3 stadials and 2 interstadials during the Weichsel glaciation are recorded on Finnmarksvidda. The oldest, possibly Weichselian, ice‐free period recorded on Finnmarksvidda is represented in one river section and is preliminary named the Vuolgamasjåkka thermomer. Its initiation is TL‐dated to about 120 ka, which indicates a pre‐Weichselian, possibly Eemian age. The interstadial which follows the subsequent and assumed oldest Weichsel stadial on Finnmarksvidda, the Eiravarri interstaeial, has previously been tentatively correlated lithostratigtrahically with the Peräpohojola interstadial ( sensu stricto ) in North Finland. The youngest interstadial, the Sargejåk internatiodial , is in this paper suggested to correlate with the Tärändö interstadial in North Sweden. The initial Weichselian ice movement across Finnmarksvidda is so far unknown, but locally N of Kautokeino in the W the initial (recorded) ice movement was directed towards NW‐N. The regional ice movements for the two subsequent stadials on Finnmarksvidda were initially directed towards NE‐ene and NNW, respectively.
