Ausblick:

-  Kartenprojeckt beenden=> Gotthard-Decke soll auch integriert werden.

-  Profile konstruieren: (1) km-scale; (2) lithospheric scale

-  Erläuterungen zu den neu gewonnen Erkenntnissen-  Karte der veröffentlichen (Druck 1: 100’000, digital?)

10

Anwendungen:

-  Gliederung der Geologie-  Bessere Rekonstruktion der geologischen

geschichte:

11

Zum Beispiel Entwicklung der Madernertal Gruppe:

-  Verknüpfung der Karte mit rezenten geologischen Prozessen (Erdbeben, Naturgefahren)

-  Hilfe für andere Projekte, i. B.: NFP70
