The Schinznach Formation was deposited in the Middle Triassic (Anisian to Ladinian; Pietsch et al. 2016, Bernasconi et al. 2017). Sequence stratigraphic analysis of the Schinznach Formation below the Asp Member identified a variable number of cycle sets (transgressive-regressive / regressive-transgressive hemicycles) as seen in the drill cores retrieved from the siting regions (Pietsch et al. 2016, Warnecke 2018, Adams & Diamond 2019).
