The Messinian salinity crisis was an event in which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation throughout the latter part of the Messinian age of the Miocene epo
Artistic interpretation of the Mediterranean geography during its evaporative drawdown, after complete disconnection from the Atlantic. The rivers carved deep gorges in the exposed continental margins; the concentration of salt in the remaining water bodies led to rapid precipitation of the salt. The inset evokes the transit of mammals (e.g. camels and mice) from Africa to Iberia across the exposed Gibraltar Strait.
Cones of gypsum, which formed on the sea floor as a result of evaporation. Evaporation of one metre of seawater precipitates around 1 mm of gypsum.
