Methods and results of detailed seismic studies of the Earth's crust in the Baikal rift zone

I.V.Litvinenko was one of the first researchers who in the process of research of the Baltic Shield, including the area of the Kola ultra-deep well, made a consistent transition from traditional low-detail work on long-length GZS profiles to highly detailed study of the Earth's crust with a corresponding transformation of the methodology of deep seismic studies.
