The Suretta Nappe is a Middle Penninic tectonic unit of eastern Switzerland made up of a Paleozoic basement of para- and orthogneisses intruded by the Permian Rofna Porphyry Complex, which consists of granitoids and effusive-type magmatites. Its Permian–Mesozoic cover, in Briançonnais facies, is largely of Triassic age. Locally the Triassic is overlain by Jurassic breccias. This cover crops out as thin layers; in one instance it follows a Suretta internal thrust fault, in other instances they are infolded into narrow synclines that were subsequently backfolded in the upper limb of the north facing Niemet-Beverin Backfold, whose axial trace runs across the Suretta Nappe.

The Lanzada Fensters, in the Val Malenco, are two small tectonic windows dominated by sedimentary rocks typical for the Suretta Nappe and surrounded by the Malenco-Forno-Lizun Nappe. These windows also expose some small occurrences of metagabbro and ultramafics that are correlated with the Avers Nappe.
