Fig. 1From: The relation between peak metamorphic temperatures and subsequent cooling during continent–continent collision (western Central Alps, Switzerland)Metamorphic map of the northern Lepontine dome using mineral occurrences of Niggli and Niggli (1965) and Bousquet et al. (2008). In addition, the isotherms from Engi (2011) are shown in °C. Note the end of all these data along the RSF (= Rhône Simplon fault). The area of Fig. 3 is indicated. The thick lines outline the Aar Massif and the Tavetsch and Gotthard nappes. The thin lines are the tectonic boundaries in the LepontineBack to article page
