The S-charl-Sesvenna Nappe (including the Tavrü Slice) in the southeastern compartment of the Engadine Fault occupies the same tectonic position as the Silvretta Nappe in the northwestern compartment of this fault.

The basement of the S-charl-Sesvenna Nappe is commonly referred to as the Sesvenna basement and its cover as “S-charl-Unterbau” (a series of NE–SW trending series of synclines and anticlines that affect both basement and cover without major detachments within the sedimentary sequence) and “S-charl-Oberbau” (nowadays referred to as Tavrü Slice, consisting entirely of a Norian to Cretaceous succession, volumetrically dominated by an over 2 km thick Hauptdolomit and completely detached from the Carnian Raibl Group).

The Trupchun-Braulio Thrust formed during a later stage of the Cretaceous orogeny. It juxtaposed the Quattervals Nappe (in the west) and the Umbrail-Terza Slice Complex (in the east) over the Ortler Nappe. The thrust is marked by calcite mylonites derived from the footwall and exhibits numerous top-WNW sense-of-shear indicators (Conti 1997).

The Upper Austroalpine Ortler Nappe overthrusts the Campo Nappe along the WNW–ESE striking Zebrù Thrust, which follows the incompetent sediments of the Raibl Group over most of its strike as the dominant basal décollement horizon. Only small occurrences of basement and pre-Carnian sediments are preserved locally, the main Mesozoic sequence being dominated by massive Late Triassic sediments. The hangingwall of the Ortler Nappe is defined by the Trupchun-Braulio Thrust that formed during a later stage of the Cretaceous orogeny and juxtaposed the Quattervals Nappe (in the west) and the Umbrail-Terza Slice Complex (in the east) over the Ortler Nappe.
