Tectonic Control

The Radkow and Szczeliniec Sandstones: An Example of Giant Foresets on a Tectonically Controlled Shelf of the Bohemian Cretaceous Basin (Central Europe)

Tomasz Jerzykiewicz, Jurand Wojewoda

Abstract

The Turanian was a period of tectonic block movements within the Bohemian Cretaceous Basin. Quiet, pelitic sedimentation in the Intrasudetic Depression (northeastern part of the basin) was interrupted by differential uplift affecting the source area (West and East Sudetic Islands) as well as the basin floor. The basin floor topography was controlled by tectonic movements that caused breaks in the shelf slope. During severe storm conditions (geostrophic storm flow?) sand transported offshore was trapped in elongate depressions bordered by fault escarpments, and formed seaward-dipping, angle-of-repose, giant foresets up to 17 m thick. On top of these, sand waves migrated offshore, as well as landward or parallel to the sea shore, under the influence of a tidal current system, probably in conjunction with wind-driven currents.
