Fig. 10

Reconstruction of thermal gradients and the missing erosional overburden in the Mittelbünden section. Different metamorphic discontinuities and the different ages of the three metamorphic patterns are shown with different signatures. The first and second deformation and the first and second metamorphic phase are restricted to the Austroalpine nappe stack. The Arosa zone is overprinted exclusively by the third event of a low-temperature geotherm. The signatures of the metamorphic zones are explained in Fig. 16. The question marks show results not well established or little constrained
