Abstrakty : Two electromagnetic (magnetotelluric and geomagnetic) soundings have been made in the region of Bornholm Island (Denmark). The results of analysis suggest a very complicated, locally three-dimensional character of the conductivity distribution; however, we interpret the outcome of the soundings in terms of a two-dimensional model, additionally using other published results from the region under study. From the interpretation it follows that Bornholm belongs to the East European Platform, whereas from the south and from the west an influence of large sedimentary basins appears. The depth of the sedimentary basin adjoining the island to the south is probably much deeper than estimated so far. Also, geological structures at greater depth in this region of the Baltic Sea may be much more complicated than it could be assumed from a simple extrapolation of data obtained from the surface geology.
