Abstract: In the composite section of San Miguel de Salinas the following synthems are represented: MI (preevaporitic Messinan), MII (syn-evaporitic Messinian) and P (post-evaporitic Pliocene). The foraminiferal assemblages of these synthems have been studied in order to reveal the palaeoenvironmental changes related to the Mediterranean Salinity Crisis. The change between MI and MII synthems is characterized by the reduction of the foraminiferal biodiversity. Synthem MII records palaeoenvironmental stress related to the evaporitic deposition during the Salinity Crisis. Synthem P marks an abrupt increase of the foraminiferal biodiversity in coincidence with the Pliocene reflooding of the Mediterranean Sea.
