LiDARstudie av glaciala landformer sydväst om Söderåsen, Skåne, Sverige

Summary, in English

The purpose of this degree project has been to review how the Weichselian ice sheet dynamics have developed from the last glacial maximum (LGM) until the deglaciation in my examination area, on and southwest of Söderåsen in Scania Sweden. Most work has been put into the interpretations of different landforms from LiDAR based elevation models and soil maps. The area includes Söderåsen, the Helsingborg Ridge and the Ängelholm Basin. These three areas have a very different geology. Söderåsen is a horst with Precambrian bedrock and only a thin soil cover, the Helsingborg Ridge is mostly comprised of Jurassic sandstone with an average soilcover of about 5 m and the Ängelholm Basin has a think soil cover with the top being draped in a fine glacial clay of greatly variating thickness. The area is complex, filled with landforms that tell of ice streams in different directions. The foremost question I am trying to answer in this degree project is to interpret these ice flows from elevation models, soil maps and literature, I also looked into some of the glacifluvial landforms to start forming an idea about the deglaciation in the area. Examinations give indications of an ice stream from the northeast that origi-nated in central Sweden and was followed by an ice stream from the south with Baltic origin that reached Söderåsen and after that changed direction from a southwest-northeast direction to a more south-north one. Thanks to the glacifluvial landforms in the area it is possible to se traces of the deglaciation until the area was ice free.
