Geometry and kinematics of the “Herbeumont shear zone” in the High-Ardenne slate belt (Belgium)

On the geological maps of the High-Ardenne slate belt (Belgium) an EW-trending, weakly S-dipping thrust fault is classically drawn, bordering the Eifel depression to the south. The ‘type locality’ of this fault lies in a – now completely overgrown – railway section at Herbeumont. This fault is indeed known as the ‘Herbeumont fault’. A detailed structural and microstructural analysis of an outcrop area on the east bank of the Semois river, south of the railway section, allowed us to complement the geometrical and kinematic context of the classical ‘Herbeumont fault’. The rocks exposed are predo... Mehr ...
