Marine Einflüsse im Mittleren Buntsandstein der Hessischen Senke – dargestellt am Beispiel des Weserprallhanges an der Ballertasche bei Hann. Münden

The abundant occurrence of the trace fossil Diptocraterion parallelum, rare Phycodes triadicum, as well as occurrence of the bivalve "Avicula" murchisoni suggest marine influence in a section of the Detfurth-Folge (Middle Buntsandstein, Lower Triassic) in the Weser Valley of Lower Saxony, Germany. Presumably, the sedimentation took place in a tidal-protected brackish(?) lagoon. The top 5 m of the Detfurth-Folge and the overlying lower part of the Hardegsen-Folge are dominated by fluvial deposits containing rare facies-crossing trace fossils (?Skolithos, Phycodes tcurvipalmalum), as well as by forms typical of non-marine environments [?Siskemia isp., Stiallia pHosa, “Cylindricum" isp.).
