New fault-slip data on post-Variscan strike-slip structures were collected in the Meuse valley between Liège and Huy, and in the area of Beauraing, Wellin and Han-sur-Lesse. These structures belong to two right-lateral wrench fault zones, developing in parallelism with the general Variscan trend: the “North-Artois” shear zone, which continues eastwards up to Liège in the North Variscan Front, and the Famenne zone in the Ardenne Allochton. Paleostress inversion of fault-slip data gives a transpressional stress field with E-W to NW-SE directions of principal compression. Together with the Husrük-Taunus Border fault zone In Western Germany, they may correspond to a Late Cretaceous – Paleogene intraplate compressional deformation, as a result of the Alpine collisional orogeny.
