Résumé :

The kinematics of internal structuration in the ≪Gaux thrust sheet≫ (Charleroi Coal basin; Belgium) is explained with the help of a geometric model. This model is controlled by the distribution of ≪ Landelies red breccia ≫ outcrops that was syntectonically deposited, probably during the Namurian. We suggest that the tectono-sedimentary evolution was controlled by (1) the growth of a Fault-propagation fold, (2) the formation of collapse structures and (3) localized interbed extension. © 1994 Springer-Verlag.
