GROUNDWATER PROTECTION IN THE NORTH GERMAN BASIN FROM THE OTHER SIDE OF VIEW - THE RUPELIAN CLAY FORMATION AS THE UNDERLAYING SEAL


GAST, Sascha, WIRTH, Holger, FISCHER, Marina and KUHLMANN, Gesa, Federal Institute for Geosciences and Natural Resources, Branch office Berlin, Wilhelmstr. 25-30, Berlin, 13593, Germany, sascha.gast@bgr.de

In northern Germany, the Palaeogene clay formation is the most important geological seal horizon between the under laying saltwater aquifers and the overlaying occupied ground-water aquifers. In context of utilisation of the deeper underground, the expanse of the Rupelian clay formation is described and the reprocessed isobath map of the “Base Rupelian as effective seal” is displayed. Exemplarily the correlation between the distribution of the clay formations and the Groundwater salinisation will be shown. The influence of salt tectonics and Quaternary erosion on the distribution and thickness of the Rupelian is discussed and revised.
