p.262: 3.3.5 The Vanis banded formation

A very characteristic, 10–15 m thick, banded formation overlies the white marble with a sharp contact. It consists in an alternation of centimeter- to decimeter-thick beds of light-colored, often slightly orange, impure marble, with dark calcschists of variable thickness. The well marked layering of these two rocks with contrasted rheological properties is favorable to folding (Fig. 11). This banded marble/calcschist association occurs very continuously above the Sevinèra marble, as well in the Val Antabia as near Campo or farther E through the Alpe di Sevinèra up to the foot of the Pizzo Castello. As it is well exposed in the northern cliff of the Vanis ravine above Campo (e.g. 683.650/142.050) we name it the Vanis Formation.
