Deep structure of the Palaeoproterozoic Onega structure on geological and geophysical data

The modern concept of the deep structure of the crust of Onega structure and its surroundings is given based on analysis of available geological and geophysical data and the drilling record for the Onega parametric borehole obtained in the past fifty years. The deep structure of the Earth’s crust of this territory was studied in more detail and its composition, possible geological nature and geodynamic setting were assessed more accurately by summing up and interpreting of geological, tectonic, geophysical and mineralogenic data.
