Fig. 16

Structural evolution of the Northern Adula nappe. a Present day geometry. The cross-section is obtained by combining the sections of Fig. 12. b Leis phase ~28 Ma. Northern Adula nappe; structures of the Leis phase. Geometry obtained by subtraction of the Carassino structures. The tilting angle of the nappe is drawn assuming a flat isograd of the Barrovian metamorphism. c Zapport phase ~32 Ma. Northern Adula nappe; structures of the Zapport phase. Geometry obtained by subtraction of the Carassino and Leis structures. Internal Mesozoic boudin trails are the result of the Ursprung phase synclines. Unconformity between trails and upper nappe limit is still visible
