Since 1958, on the territory of the eastern part of the Baltic Shield, on the initiative and under the direction of I.V. Litvinenko, a large volume of seismic studies by the DSS method has been carried out.
The zone of juxtaposition of the southeastern part of the Baltic Shield and the Russian Plate covers the territory of southern Finland, southern Karelia and the Baltic States. To date, a significant amount of deep seismic research has been carried out here on several northeast-directed profiles.
In the territory of the south-eastern part of the Baltic Shield, observations by the DSS method have been carried out so far along the profiles crossing the main structures of this region: Baltia, Sveka, Lahdenpokhya - Lake Segozero, Pitkäranta - Sapasero, Pitkäranta - Sapasero. Pitkäranta - Spasskaya Bay.
In 1980 in the northwestern part of Ladoga and southwestern Karelia the production and geological association Sevzapgeologia and the Problem Research Laboratory of geological and geophysical studies of the Baltic Shield of the G.V.Plekhanov Leningrad Mining Institute conducted deep seismic studies by methods of deep seismic sounding and exchange waves from distant earthquakes (MOB3) along the profile and the Problem Research Laboratory of Geological and Geophysical Research of the Baltic Shield of the Leningrad Year Institute named after G.V. Plekhanov conducted depth seismic studies by methods of depth seismic sounding (DSS) and exchange waves from distant earthquakes (MOVZ) along the profile of Lahdenpokhya - Lake Segozero, which is hereinafter referred to as the Priladozhsky ...
On the territory of the Karelian-Kola region, mass explosions in quarries and mines are successfully used as sources of elastic vibrations for seismic studies of the deep structure of the Earth's crust ...
High weight of charges, release from cumbersome drilling and blasting operations, and the resulting savings and protection of the ecological environment are obvious advantages that determined the problem laboratory of the LGI to set up work on the registration of seismic waves arising from industrial explosions and their use to study the structure of the Earth's crust in the eastern part of the Baltic Shield ....
As a result of the gravity survey carried out by the Western Geophysical Trust (WGT) in 1962, two anomalies were detected on the eastern shore of Lake Onega, which turned out to be associated with rocks of basic and ultrabasic composition, occupying an area of more than 1,000 km2. The area of the anomalies was named the Burakovsko-Aganozerskaya zone of basic and ultrabasic rocks. ...
On the Baltic Shield, in foreign and Soviet parts of it, to date, a large amount of work has been carried out by methods of explosive and conventional seismology, allowing to determine the sole of the consolidated crust - the Mohorovičić discontinuity (M) - in its various areas.
