p.71: The Lower Penninic subdomain of central and eastern Switzerland is represented by flysch nappes of controversial origin in the external part of the Alps and essentially by metasedimentary, mostly shaly-calcareous units (so called “Bündnerschiefer”) further south, deposited in the oceanic Valaisan Basin. Ophiolitic remnants are found at the base of some of the “Bündnerschiefer-type” nappes. The Chiavenna Nappe is a large ophiolitic slice found below the Middle Penninic Tambo Nappe and against the Gruf Complex, and thus considered as a remnant of the Valaisan oceanic crust. Lower Penninic sediment units form the Prättigau Half-Window and the core of the Lower Engadine Window.
