Bertle Rufus J. (2004) : The Sedimentary Record of North Penninic Schistes lustrés of the Lower Engadine Window and its Correlation to the Tauern Window (Eastern Alps). Jahrbuch der Geologischen Bundesanstalt 144/2, 165-171

p.167: They are in turn overlain by a sedimentary sequence of turbiditic character: the Malmurainza Formation. It consists of a rhythmic layering of dark shales/phyllites and sandstones with some few intercalated coarse grained breccias. The age of the Malmurainza Formation is late Cretaceous in general, an early Tertiary age cannot be excluded, as the tectonically highermost part of the Zone of Pfunds is latest Cretaceous taceous in age, indicated by Lepidorbitoides sp. and Globotruncana ex gr. arca (BERTLE, 1999).
