Messinian salinity crisis

1. (geology) A geological event, characterised by the partial desiccation of the Mediterranean basin, which occurred throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 million years ago, and finally ended with the Zanclean flood.

   Synonyms: Messinian event, MSC

     Our isotopic and sedimentologic correlations demonstrate that the latest Miocene expansion of the West Antarctic ice sheet preceded and most likely precipitated the Messinian salinity crisis.

     It is an evaporitic and carbonate unit which marks a peripheral manifestation of the Messinian salinity crisis, during which huge volumes of evaporites were produced in the deep Mediterranean basins.

     A research program found that the great drying commenced about six million years ago during the Messinian age, the last stage of the Miocene. Known as the Messinian salinity crisis, it resulted from the clockwise rotation of Africa, which closed the Strait of Gibraltar and isolated the Mediterranean from the Atlantic Ocean.

     The Messinian salinity crisis (5.85–5.35 Ma) represents a nearly unprecedented unloading and loading event. During the Messinian Salinity Crisis, two important things happened in terms of surface load changes—the accumulation of thick evaporites represent a load addition, while the desiccation of the Mediterranean represents a load subtraction.
