Figure 5. Reconstruction of the geologic evolution from Bathonian to Tithonian times. The radiolarite section Mischenirwiese is a complete radiolarite succession, reworked material from the advancing nappe stack, which consists of different Hallstatt imbricates, is missing. In Oxfordian times the succession was overridden by the Hallstatt mélange, which formed contemporaneously more to the south as indicated by the different radiolarite matrix ages. In Kimmeridgian– Tithonian times this tectonic nappe stack was sealed by the Plassen Carbonate Platform sensu latu (Lärchberg Formation; see Figure 2).
