Figure 9 in Facies, origin, and palaeontological inventory of an Early Carboniferous neptunian dyke in the Devonian reef limestone near Rösenbeck (Brilon Anticline, Rhenish Mountains)
Figure 9. Schematic diagram illustrating the genesis of the dykes and their sediments in the Rösenbeck quarry. (a) Early Late Devonian: end of reef limestone sedimentation. (b) Late Devonian to Tournaisian: collapse of the carbonate platform, formation of fissures and dykes. (c) Late Tournaisian to Viséan: accumulation of carbonates on top of the reef ruin, widening of the dykes. (d) Late Viséan: begin of filling of the dykes by shales. (e) Latest Viséan to early Serpukhovian: transport of eroded sediment blocks from the top of the reef ruin into the dykes. (f) Serpukhovian to Recent: complete filling of the dykes with mud, erosion of the reef complex.
