S.2: On top of the "Detritische Basis-Serie" follows a sequence of bright to dark gray dolomites, rauhwackes and locally dark limestones which are informally called the "Karbonatische Mitteltrias". These wellbedded carbonates show the various features of sub- to supratidal platform sediments that have been formed under low energy conditions. Only a very poor fauna can be found, which gives no other date indications than Ladinian.
