Gravity Mapping and Modelling of Buried Quaternary Valleys in Southern Jutland (Denmark)

A047 Gravity Mapping and Modelling of Buried Quaternary Valleys in Southern Jutland (Denmark) Abstract 1 Buried valeys in Denmark are utilised for water supply and are the object of intensive investigations to ensure future water resources. Geophysical techniques are applied to localise and outline the structure of the valleys. Gravity surveying is suitable to detect small and in many cases positive anomalies of the valleys within the Earth’s gravity field. In the case of the Bredebro valley situated in southern Denmark mapping has successfully been used to outline the lateral extent of the valley while inversion of the residuals gave
