Environment/lithology: terrestrial; gray shale

• The Bohemian Cretaceous Basin and its source terrains formed during the mid-Cretaceous, by reactivation of a system of anastomosed strike-slip faults. Individual sub-basins and source terrains formed within this anastomosed fracture system. The structurally deepest depocentres of individual sub-basins were situated along the most active marginal fault zones. Compared to the classic strike-slip basin systems, this intracontinental setting was characterized by small subsidence rates.
