dc.description.abstract |
The Messinian and Pliocene stratigraphic record in the Palma basin (Mallorca) shows four stratigraphic units and two majors unconformities. The Reef Unit (late Tortonian-Messinian) recorded the pre-evaporitic marine sedimentation (pre-Messinian Salinity Crisis). This unit is limited at the top by the intra-Messinian unconformity, representing a subaerial erosive phase related to a first major sea-level fall. The evaporitic marginal episode is characterized by the Terminal Carbonate Complex changing basinward into massive selenite gypsum. The post-evaporitic deposits (latest Messinian) are characterized by lacustrine-continental sedimentation, related to the so called Lago Mare episode. At the top of the Lago-Mare Unit is located the fini-Messinian unconformity, caused by a second major sea-level fall. Over this unconformity lies the Pliocene Units (early Pliocene), represented by marine deposit which marks a transgression, and the subsequent final of the Messinian Salinity Crisis. |
