Grey and brown mudstones and marls at the bottom, increasingly sandy towards the top with intercalated limestone beds.
Total thickness: approx. 23m
As a special feature, characteristic red-brown clay marls occur near the base, which are called Schattwald-beds (about 3 m in the Karwendel Mountains).
Approx. 6m above the base of the Tiefengraben Subformation, the Triassic/Jurassic boundary is defined at the Kuhjoch (cf. HILLEBRANDT et al. 2013).
They are red, brown, ochre limestones, very often with strong enrichment of iron oxide in the form of crusts and impregnations.
Characteristic is a very iron-rich, ochre-coloured lime, which was also called "Enzesfelder Kalk" in a broader sense.
The Schnöllkalk can be sparitic or micritic and always ends with a continuous iron crust ("marmoreum crust").
Characteristic features at the top are iron-encrusted rock clasts, ammonite nodules, generally a colourful mixture of various redeposited rock components.
The limestone is formed in all outcrops and is 0.1 to 2m thick.
The marmoreum crust is always followed by a micritic red to reddish brown limestone containing iron oxide in the form of concretions. These concretions can vary in size and frequency. They are a few mm to 20 cm in diameter. Often the rock is speckled with them.
Above the Lienbach Subformation, the red nodular limestone of the Lias (Adneter Limestone) almost always follows.
