Polymetamorphic blastomylonitic paraschists (pre-Alpine deep continental crust) outcrops. High-grade metasedimentary gneisses transformed to schists during Alpine metamorphism. Presence of metabasites, marbles and migmatitic leucosomes.

The association of high-grade pre-Alpine schists and marbles includes minor metabasics that widely preserve relics of brown hornblende and clinopyroxene predating the development of the pervasive Alpine foliation. The early
Alpine foliation is marked by chloritoid + glaucophane +/-kyanite + white mica in the metasediments, indicating blueschist facies peak conditions. In metabasic layers the Alpine foliation is marked by colourless amphibole +
clinozoisite + white mica + titanite. This tectonometamorphic unit (TMU) is bounded by decametre-thick discontinuous mylonitic horizons marked by colourless amphibole + chlorite + epidote + albite + quartz + titanite. These mylonites separate the Monte Croass TMU from the surrounding gneisses and
micaschists of the Sesia-Lanzo Zone that recorded the early Alpine eclogitic
imprint.
