of early diagenesis (i.e. eogenetic stage). Based on speleological analysis the eogenetic caves were grouped into four types; (1) linear stream caves, (2) shelter caves, (3) breakdown caves, and (4) vadose shafts. - (IKR)

The Port Miou system (Cassis, France) is a long submarine gallery developped in the limestone series of Calanques (Marseille, France). Its speleological exploration suggests a deep karstic system higly polluted by seawater. The strong geochemical
signature of the titanium in the surface sediment supports the model of a sea water aspiration in a deep gallery connected to the Cassidaigne canyon. This speleological model of sea aspiration explains why all the attempts to diminish the salinity
damage. Results of the hydrogeological surveys and the speleological and geomorphological fiedwork. Discussion about this hypogene karst, completely invisible at the surface, making up extremely dangerous situations.
