Abstract

Johnsson, Gunnar: Nivation hollows and valleys in the fossil coast cliff Landborgen at Heisingborg, South Sweden. Geografisk Tidsskrift 91: 26–37. Copenhagen 1991. In the fossil coast cliff Landborgen at Helsingborg North- West Skane (Scania), there are many hollows and broad valleys which begin blind with a semicircular back rim. These hollows and valleys were probably formed mainly by nivation in the bedrock of Lias sandstone and shale. The hollows mostly have a cirque form with an opening towards the cliff. Some of them continue as broad valleys containing a rill of water. Most of the main nivation hollows and valleys are older than the last phase of the Weichselian glaciation as indicated by the fact that they contain till or morainic boulders from the north eastern ice, the main ice stream in Skane during the last glaciation. Hydro-thermal water has made hollows and rill water small valleys in the cliff where the nivation processes begun. The nivation processes were caused by drifting snow from the e...
