Schematic description of the sedimentological situation (left), outcrop photographs, and event stratigraphic interpretion of the sedimentologic succession (right) in the Tobel Oelhalde-Nord (Hochgeländ plateau south of Biberach an der Riß; outcrop no. 2 in the text). Two seismic events (Ries and Steinheim impact-earthquakes) are reported by the occurrence of the Ries seismite horizons with slumps and convolute bedding within sediments that formed the land surface at the time of the impact event, capped by distal Ries ejecta. The second impact-earthquake (Steinheim impact) caused the formation of a giant clastic dike that reached the palaeo-surface at the time of the second impact event. A succession of about 15 m of OSM sediments were deposited in the timespan between the two impact events; for more details about this outcrop see16; all photographs taken by V.J.S. in 2018–2019.
