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.
