Abstract

Silurian-Devonian slump structures, including intraformational breccias, are object of study in the Barrandian area (Prague Basin). (The mudflow breccias and slump structures of the Zlíchov Formation are excepted from this paper.) The slump structures are generally rare. They occur most frequently within the Lochkovian Stage (Radotín Limestones) and at the base of the Pragian Stage. The latter are intraformational breccias, being probably due to the Lochkovian-Pragian boundary shallowing event. The other slump structures are within the Wenlock and Ludlow Series. Some of the previously described structures, interpreted as tectogenetic deformations, are attributed to submarine slides.
