The results of geological interpretation of large fragments of seismic transects SB-1 (Batolit), SB-2, and SB-3 (Altai-Severnaya Zemlya), which cross the western and southern margins of the Siberian Platform and its fold framework, specify substantially the structure and geological history of the sedimentary cover. The most important data have been obtained for the structure of the Baikit Anteclise, the Angara-Lena Terrace, and the Kas Block of the West Siberian Plate. The geological interpretation of the recorded wavefield specifies substantially the genetic features of these structural elements and their mutual relationships, allowing a reliable reconstruction of the western, and partially the southwestern, margins of the Siberian Platform in the Riphean-Early Paleozoic before and after the Baikalian Orogeny.
