p.76: The Falknis and Sulzfluh nappes discontinuously overlie thick Lower Penninic “Bündnerschiefer” and flysch of the Tomül Nappe in the Prättigau Half-Window. They consist of a series of Early Jurassic to Paleogene sediments of Briançonnais origin. The tectonically lower Falknis Nappe is characterized by a more than 200 m thick Kimmeridgian – Tithonian Breccia overlain by Tithonian – Barremian marly limestones, Barremian – Aptian sandy limestones and fine grained breccias (Gruner 1981). The tectonically higher Sulzfluh Nappe differs from the Falknis Nappe in that only massive limestone instead of breccia represents the Late Jurassic sediments. In a few places, crystalline basement lenses occur at the base of the Sulzfluh Nappe. The mid-Cretaceous to Cenozoic quartzbearing sandstone and Couches Rouges are the same in both these nappes. The Falknis Nappe is particularly well developed in the area of the eponymous summit where it is subdivided into several slices. In places, one or the other of these two nappes becomes thinner; in these cases, only the thicker nappe is indicated on the map.
