| Abstract | GPR profiles of different length and with different antenna frequencies were recorded In order to reconstruct landscape genetic investigations at a Neolithic exposure. In a first survey, a 400 MHz antenna was applied. Radargrams were depth migrated and reflections were correlated with layers found in an exposure survey. The velocity-depth distribution was determined with multi offset CMP measurements. The boundary between soil colluvium and the underlying parent material (Weichselian till, glaciofluviatile sand) and differentiated layers within the soil colluvia was found in both velocity and reflections. It was possible to calibrate GPR reflections with colluvial layers and the glacial basis at the exposure and to continue mapping these prominent layers in the non-disturbed surrounding areas. Seasonal effects with its different soil water content situation have only a small influence on the interpretation. However, under conditions of increased soil water content, the glacial basis turned out to reflect more brightly because of the ponding effect of thin clay layers of a lamellic luvisol. In a second survey a 200 MHz antenna was applied to explain previously found sloping horizons by considering deeper structure. It turned out that the Neolithic side is underlain by a glacial trench. All information, mapping colluvial layers and the glacial basis in their lateral dimension and locating the huge glacial trench, are considered as important details to reconstruct historical processes in the young morainic area. Especially, mapping of the glacial trench is an important evidence for the assumed sag and swell topography. Due to its non destructive and near surface applicable character, GPR technology has the potential to improve landscape genetic investigations, which previously, have been based only on point information such as exposures, auger cores. |
