Descrizione

Descrizione

Mikrokonglomerat mit Geröllen aus nordhelvetischen Einheiten (Spätjura, Kreide, Paläogen), gefolgt von einer Wechsellagerung aus einem glimmerreichen, sandigen Kalk und einem feinsandigen, plattigen Mergelstein. Gegen das Dach des Members dominiert der Sandstein.

p.188: The Kistenstöckli Member was described by Styger (1961; ‘‘Kistenstöckligipfelsandstein’’, ‘‘Kistenstöcklisandstein’’), the type locality forms the peak of the Kistenstöckli (2720.650/1186.350). For further descriptions see Arn. Heim (1908) and Brückner (1952). Lithology: A microconglomerate bed with partly rounded fragments of North Helvetic Late Jurassic and Cretaceous strata as well as Palaeogene sandy limestones follows above 100–150 m of slaty Stad Formation that become more calcareous towards the top. It is succeeded by an alternation of 100–200 m of well-bedded, mica-rich sandy limestone and fine-grained, sandy, slaty marlstone; sandstone dominates the top. The formation of the microconglomerate presumably suggests Late Eocene fault tectonics. Overyling stratum: Taveyannaz Formation; underlying strata: Stad Formation. Biostratigraphy: Priabonian, Larger foraminifera. Current geographical extent: Eastern Switzerland: Kistenpass region. Tectonic unit: Eastern Switzerland: Lower Helvetic (Parautochthonous).
