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.
