Abstract
The ''Entre-deux-Mers'' region (Gironde), is a moving panel of the sta ble North-Aquitaine margin. It is overlain by Oligocene shallow water carbonate deposits with high porosity (grainstones, packstones, bounds tones), or low porosity (mudstones and wackestones) facies. During the Plio-Pleistocene period, a fault system, resulting from Pyreneo-Alpin e orogenesis, induced a karstic network related to tectonic fracturati ons, high porosity Oligocene facies distribution and glacio-eustatic s ea-level variations.
