Abstract:
In karstic areas, tectonic phenomena have two major influences. (i) By uplift, they give potential energy to karst and valley hollowing. (ii) An active tectonic regime is necessary for the development of karstification. The opposition between the development of valleys or karstic networks depends on the type of dissipated energy. Karstic systems in the Ardennes Massif are essentially between 5 and 15 m above the water table for the dry networks, and in the phreatic zone for the active parts. The structuration of the karstic systems is dependent on the uplift of Ardennes and an active tectonic regime is necessary for the genesis of large caves. It is during the Upper and Middle Pleistocene that the Ardennes area underwent tectonic activity; these karstic levels are more than 400 000 years old.ResumeDans les regions karstiques comprenant des vallees epigenetiques, les phenomenes tectoniques ont deux influences majeures: a) la surrection donne de l'energie potentielle en creant des differences d'altitude, generant a la fois le creusement des vallees et celui du karst; b) une tectonique active est necessaire pour que le processus de karstification debute. L'opposition entre le developpement privilegie soit des vallees, soit des reseaux karstiques depend ainsi du type d'energie dissipee. Les reseaux karstiques de l'Ardenne se situent surtout entre 5 et 15 m au-dessus de la surface piezometrique pour les reseaux secs, et dans la zone saturee pour les parties actives. La structuration de ces reseaux karstiques est favorisee par un ralentissement de la surrection et une activite tectonique. Cette periode se situe dans le Pleistocene moyen et recent, d'apres les datations U/Th de speleothemes
