The Bänkerjoch Formation was deposited during the transition between Middle and Late Triassic (Ladinian to Early Carnian; Kozur & Bachmann 2008, Bernasconi et al. 2017). Three timelines have been picked within the Bänkerjoch Formation (237_Lad_300, 237_Lad_200, 237_Lad_100). The two older timelines approximately follow the «Banded massive anhydrite» facies, which is interpreted as being deposited during roughly the same period (Fig. 4‑11). The younger timeline approximately follows the top of the «Cyclic sequence».
