The subsurface Silurian in the East European Platform

A state of art overview of the Silurian System within the deep substratum of the East European Platform (EEP) is presented. Structural Regions are charac terized in terms of biostratigraphy, tectonics and palaeogeography. The most instructive sections based on keywells have been briefl y described with an emphasis on the western margin of the platform. The Silurian basin displays a typical platform development and may be traced from the neritic to the deep basinal facies. While the neritic belt is recognized from Gotland through Estonia, Volhynia to Podolia, the deep basinal facies has been documented NE of the Tornquist-Teisseyre lineament. The results presented are based on some 700 deep borings. They offer a summary of Silurian history
