The Arosa section, modified from Streckeisen 1948 with the location of the KI (∆°2θ) and vitrinite reflectance (Rmax%) measurements. In the section below the values are combined to draw metamorphic zones. At three localities, spots of the epizone are related to occurrences with a Jurassic hydrothermal oceanic metamorphism
