Fig. 4

Simplified tectonic map of the Alps (based on Bousquet et al., 2012b; Schmid et al., 2004), showing characteristic fissure orientations (perpendicular to σ3) and best Miocene (red lines) and Plio-Quaternary (blue lines) σ3 axes of paleostress data obtained by Bertrand and Sue (2017). The color of the fissures is according to the oldest fissure monazite crystallization age recorded for a fissure generation. For regions lacking fissure monazite, the attribution is based on the age of the metamorphic overprinting. Some data are from Kandutsch et. al. (1998) and Sharp et. al. (2005).
