Karsts et paléokarsts du bassin de Mialet (Bordure Cévenole, Gard) : formation et évolution d'un karst démantelé

Abstract : The Mialet basin is a limestone massif of 62 km 2 on the edge of the Cévennes Mountains, made of 400 m of limestones and dolomites. Two allochtonous rivers (Gardons) cross and dissect it. Many caves are to be found at each level and their formation cannot be explained with today's topography. Surface karstic features (dolines) are rare but karstic fillings and many speleothems can be observed on the surface. These deposits are former karst (paleokarst) cut by rivers incision. Recent karstic systems are organized differently but new subterranean circulations sometimes flow in old galleries and declog them.
