p.53: The small Soja Nappe includes a polycyclic crystalline basement covered by Permian to Jurassic sediments. It is located below the Adula Nappe in its frontal part, where it is wedged between this latter nappe and the Simano Nappe. To the north, it extends into the Garzott Slices located in the core of the Lunschania Antiform and surrounded by the Piz Terri-Lunschania Nappe. Due to this structural position, Galster et al. (2012) attached the Garzott Slices to the Piz Terri-Lunschania Nappe, but the facies analogies bring them closer to the Soja Nappe (Vögeli et al. 2013). A paleogeographic origin of the Soja Nappe between the Piz Terri-Lunschania Nappe and the Adula Nappe is plausible.
