Evaporite rocks which have suffered a succession of deformation during the formation of the Alps between the upper Eocene and Oligocène, associated with high pressure metamorphism, then a metamorphism of the "green schist" type.
The outcropping Triassic evaporitic rocks of the so-called Maurienne gypsum nappe (or "Nappe des Gypses" formation) consist of a sedimentary sequence of evaporites (mainly anhydrites), marine carbonates (dolomite), and clay layers (micaschists). Anhydrite rock is the most abundant rock of the sequence. Sedimentary bedding is underlined in white anhydrite by numerous pale gray layers that are commonly folded. Due to massive recrystallization, alpine foliations are most of the time invisible. Marine carbonates consist of centimeter to meter scale beds of grey dolomite. As these carbonate beds have been strongly folded and stretched by Alpine tectonics, they form various scale blocks more or less rounded and elongated within the main anhydrite layering, called "boudins". A secondary white dolomite, in which no sedimentary structures are visible, is frequently observed around marine carbonate blocks. Sedimentary clay layers have been transformed into micaschist rich in phengite by Alpine metamorphism.
Quartz and fluorite crystals from the evaporitic sequence contain fluid inclusions (Barré et al., 2020).
