The Tsaté nappe in the Aiguilles Rouges massif near Arolla displays a wide range of weakly metamorphic remnants of the Jurassic Piemonte Liguria ocean, including sediments, pillow basalts, gabbros and ultramafic rocks. This 1 day excursion will provide an excellent opportunity to discuss the origin of these rocks, their overprint during Alpine metamorphism and their paleotectonic importance.
