Figure 5 in Facies, origin, and palaeontological inventory of an Early Carboniferous neptunian dyke in the Devonian reef limestone near Rösenbeck (Brilon Anticline, Rhenish Mountains)
Figure 5. Carbonate microfacies of selected samples from the Rösenbeck quarry; all ×2. A – Middle Devonian reef limestone; B–F – Early Carboniferous dyke sediments. (a) Sample A: Stromatopora–Tabulata rudstone. Bioclast- and lithoclast-supported facies with fragments of stromatoporoids, tabulate corals (Thamnopora), and fragments of rugose corals and bivalves without preferred orientation. (b) Sample B: ammonoid packstone. Densely packed fragments of ammonoids within micritic matrix; some areas are filled with pseudosparite. Bioclast voids are filled with sparry calcite and displaying geopetal orientation. Ammonoids of various sizes from the initial stage (1 mm in diameter) up to 20 mm (but then fragmentary) are packed without preferred orientation. Numerous mollusc shell fragments (probably also mostly from ammonoids); less abundant are remains of ostracods, trilobites, and foraminifera. (c) Sample C: thin section with two successive carbonate facies. The lower part is a mollusc packstone with micritic matrix in which particularly small ammonoids up to 2 mm diameter are present; larger specimens are fragmented. Separated by a sharp boundary follows (in the upper part of the thin section) an ammonoid rudstone with densely packed ammonoids up to approximately 8 mm conch diameter. (d) Sample C: densely packed bioclastic and lithoclastic packstone with strongly fragmented mollusc shells and well-rounded clasts of phosphoritic nodules up to 10 mm length. Further biogens include ostracods, foraminifera, and conodonts. (e) Sample E: mollusc packstone with micritic matrix, which in some places is replaced by pseudosparite. Bioclast voids are filled with sparry calcite and show geopetal orientation. Most of the bioclasts are probably ammonoid shell remains; only one specimen is rather well preserved with internal whorls (Calygirtyoceras sp.). Further biogens are orthoconic cephalopods, ostracods, and trilobites. (f) Sample G: wackestone with occasionally occurring ammonoid conchs.
