Sandy till characterized by ground-penetrating radar

Abstract

Ground penetrating radar (GPR) has been used characterising sandy till deposits in Denmark. 2D GPR surveys are carried out at several field sites, known from the geological mapping to be located on sandy till deposits. Some field sites turned out to have a high geological variability with several different glacial deposits. Although, it is possible to bound areas with sandy till in the uppermost layer, mainly on penetration depth, but also on reflection pattern and amplitude strength. Results from the GPR surveys show that there are similarities between sandy till deposits from different localities.
