Descrizione

Paragneiss, ultramafitites (Peridotite del Moncucco) et schistes à grenat deux micas et plagioclase. Ce socle est recouvert par l'unité de Salarioli (couverture sédimentaire permo-mésozoïque) et représente les racines méridionales du socle cristallin de Berisal, des Staldener et Visperterminen-Lappen et de la Zone Houillère.

Definizione
Steck Albrecht (2008) : Tectonics of the Simplon massif and Lepontine gneiss dome: deformation structures due to collision between the underthrusting European plate and the Adriatic indenter. Swiss J. Geosci. 101, 515-546

p.517: The Ruginenta unit, named after a village in the Antrona valley, comprising a basement of similar composition of the Camughera basement, which is stratigraphically overlain by the sediments of the Salarioli unit (Fig. 4; the “Salarioli mulde” of Bearth 1956b, consisting of Permo-Mesozoic sediments), composed of 10–180 m thick black graphite-rich slates, sandstones and microconglomerates of probable Carboniferous age, followed by 1–10 m of Permo-Triassic phengitic quartzites and above this, boudins of 5–100 m thick Triassic dolomites with less than 10% of calcite and quartz. The contact to the higher Camughera gneisses is tectonic; on the Pso d’Ogaggia it is marked by several meters of cornieules.

p.64: South of the Simplonpass, the Ruginenta Nappe consists of a polycyclic basement, comparable to that of the previous two units, intruded by a granite and overlain by a Carboniferous – Triassic sedimentary cover. The Ruginenta Nappe overlies the Moncucco Nappe and is overlain by the Camughera Nappe in the huge Vanzone Antiform (Steck et al. 2015). If the Camughera Nappe is a continuation of the Siviez-Mischabel Nappe (see below), the Ruginenta Nappe may be a continuation of the Upper Stalden Nappe.
