The aim of presented research was to rec ognize a fine geological structure of post-glacial sedimentary forms. The survey was conducted in the South Pomeranian Lake District (north - western Poland) in the vicinity of Pile Lake and Strzeszyn Lake. The geoelectrical equipment Terrameter SAS 4000 (ABEM) with LUND Imaging System was used for the measurements of apparent resistivity of rock mass. The resistivity imaging was carried out im plementing Schlumberger S-protocol with 41 electrodes. Research was done along profiles crossing a border between two sedimentary forms. It allowed to recognize and compare the layered structures of the different post - glacial deposits down to 70 meters be low the surface. The data were interpreted on the base of two-dimensional inversion methods. Results were corre lated and compared with geological dat a accessible in the literature concerning of the research area. Geophysical prospecting gave good results and allowed to recognize a fine geological structure of the deposits., Adam F. Idziak and Anna Wysowska-Świebodzińska., and Obsahuje bibliografické odkazy
