p.12: The upper part of the Grünten Member is composed of an up to 20 m thick succession of sand-bearing crinoidal carbonate, which may contain chert nodules and discrete levels of orbitolinid pack- and grainstone. In the Fronalpstock area this unit is topped by an oolitic grainstone (Gigandet 2005).
