p.431: On their tectonic map of the Simano nappe, Keller et al. (1980) distinguished a northern Campo Tencia unit composed of staurolite–kyanite–garnet micaschist and biotite-plagioclase paragneiss (meta-graywacke), the latter intruded by the Ganna granite gneiss, from a southern zone, dominated by a granitic two mica augengneiss, the 300 Ma old Verzasca gneiss (Ko¨ppel et al. 1981). A discontinuous zone of amphibolites follows the contact of the two units. The contact of the Campo Tencia and Verzasca units resemble a shear zone (Keller 1968).
