Breccias with phosphorites constitute a distinct lithology in Lower Carboniferous of the Moravo-Silesian basin. This facies constitutes lens-like bodies sandwiched between preorogenic sediments and younger synorogenic turbidites (“Culm” facies). This facies represents a key lithology in our understanding of the transition from the passive margin to the foreland basin stage of the MSB. Detailed description of facies, allochem composition and biostratigraphy indicate that the breccias were deposited on toes of submarine slopes and contain significant proportion of reworked material. The onset of breccia sedimentation was diachronous within the interval from middle Tournaisian to early Viséan. The breccias are always underlain by Famennian carbonates suggesting there is always a distinct hiatus associated with their basal surface. The breccias are in places accompanied by neptunian dikes filled with upper Tournaisian detrital sediments. The features of the breccia sedimentation suggest a local controls acting during their deposition in a fault-related setting. This is also supported by the Famennian to Tournaisian differential subsidence patterns derived from isopach maps. Therefore, the breccias recorded important tectonic events at the transition from the passive margin to the deep-marine foreland basin stage of the MSB.
