Deep seismic studies in the southeastern Fennoscandian Shield

The modern concept of the deep structure of the earth crust of the Ladoga-Bothnian zone, based on analysis and summing-up of all available information obtained in the last 35 years, is presented. Tomographic models were constructed, our concepts of the stratification of the earth crust and the geome...
