FACIES B

Fig. 4. Main seismic facies types observed on seismic profiles. Facies A is associated to crystalline basement: Facies B, corresponding to
carbonate platforrn rocks, is calibrated also by wells; Facies C is generated by thin bedded pelagic carbonates; Facies D corresponds to
argillaceous successions: Facies E is representative of the Messinian evaporites; Facies F is typical of sandy and marly successions.
