Evaluation of seismic 2D- and 3D data together with well correlation, allowed a regional ...
  • Kortejärvi Veiki moraine plateau - a key to the glacial history of northern Sweden 

    Lindqvist, Mimmi Adina (Master thesis; Mastergradsoppgave, 2020-03-30)
    In many parts of Scandinavia, the glacial history is more well established than in northern Sweden. The Veiki moraines in northeastern Sweden presumably store information about the Weichselian glaciations. The moraines were formed when stagnant ice was slowly melting under a thick debris cover, forming water filled sinkholes, that were left as elevated ice-walled lake plains when the ice finally ...
