Abstract
The Sainte Baume karst (Bouches du Rhône and Var, France), structure and evolution : the hydrogeological approach The Sainte Baume range constitutes the highest and most southern mountain of Basse-Provence. Its complex structure is due to an Upper Eocene tectonic overthrust, however, the main karstified part has developed after the Upper Miocene. Some of the most important springs have been studied and their hydrodynamical and physico-chemical characteristics are given. These results reveal two main types of springs : - springs resulting from important karstification where infiltration dominates and water transit is rapid ; - springs resulting from meagre karstification, poorly drained, where a certain storage of water controls their action. This second type of springs appear to be related to a poorly organised deep drainage level, which partly feeds a coastal karstic system (Port-Miou).
