Seismic refraction investigations, performed in Poland between 1964 and 1978, are reviewed. Examples selected from the many seismic profiles, totalling approximately 15 000 km in length, are shown. The most useful profiles as regards geological interpretation are in the Precambrian Platform and along its southwestern edge. Both the top of the crystalline basement and a system of faults, downfaulting the basement towards the south-west, can be identified in that area. In the Carpathians and its foreland, the top of this basement may be identified together with the bases of thrust flysch nappes. In the Fore-Sudetic Monocline, the top of folded Carboniferous deposits can be determined. The most ambiguous results were obtained from the Palaeozoic Platform.
