Interpretation of the kinematics of the northern Adula nappe. a Zapport phase ~32 Ma. Kinematic evolution of the northern Adula nappe into the eastern Lepontine nappe stack. The deformation mechanism is essentially a ductile top-to-N shear. b Ursprung phase. Kinematic evolution of the northern Adula nappe: formation of the south vergent Internal Mesozoic synclines on the top of the nappe and onset of the ductile nappe emplacement
