Abstract The Baltic basin overlaps the SW margin of the East European Craton (EEC). During the Silurian its subsidence was governed by the flexural bending of the EEC margin due to the collision of Eastern Avalonia and Baltica. Two mechanisms — orogenesis and dynamic loading — were responsible for the flexural subsidence of the basin. Lithofacies, sequence- and cyclo-stratigraphic analysis were applied to reveal the tectonosedimentary evolution of the Silurian Baltic Basin, focusing on the imprint of geodynamic processes in adjacent orogens on the sedimentary architecture. Adopting a sequence stratigraphic approach, 10 depositional sequences superimposed by the lower rank cycles were identified in the Silurian Baltic Basin. The Llandovery sequences correspond with the initial stage of flexuring. The low terrigenous influx to the basin is explained by the lack of relief in the fold belt and its location at a distance from the orogenic front. The Wenlock-Lower Ludlow sequences reflect the accelerating flexuring. An increase in orogenic-sourced terrigenous material indicates the advancement of the Caledonian orogen. The Late Ludlow–Pridoli sequences comprise the final stages of flexuring and basin infilling. Two major provenances — cratonic and orogenic — competed to supply terrigenous sediment to the basin during Silurian times.
