Figure 7: Mineral distribution (and some associated PT paths) of collision-related processes in post-Hercynian metasediments of the Alps. Two types of metamorphism can be distinguished. The lower one up to greenschist facies conditions has a large distribution all over the Alpine Belt and occurs in the external part. The second type is characterized by an important thermal event from greenschist to granulite conditions. It occurs only in three specific areas (Tauern, Lepontine dome and Tuscany). In these areas, the thermal event can overprint an earlier HP event.
