Crystalline basement of the Polish part of the Baltic Sea
New geophysical data and the results of the petrographic investigation of the rocks derived from boreholes performed in the Polish area of the southern Baltic Sea enabled to compile the schematic geological map of the crystalline basement surface. In the south-western part the basement is probably c...
