In the Miocene, during the time interval from 12 to 5 million years ago, global hydrodynamic
and lithodynamic processes occurred in the Caspian-Mediterranean region, the consequences
of which were generally positive for the development of modern civilization. These include
several time-shifted processes of formation of the Paratethys seas and their sudden
disappearance; the formation of the Bosporus, Dardanelles, and Manych straits; evaporation
of water in the Mediterranean Sea and its secondary infilling with ocean water; the formation
of the Gibraltar Strait; vertical movements of the earth's crust caused by changes in pressure
on the bottom of the Mediterranean Sea; and the formation of the deep-sea basin of the Black
Sea. All these processes were interrelated and exerted a certain influence on each other. In the
1970s, a mathematical model that described the main changes in the Mediterranean Sea and
the formation of the Gibraltar Strait during the Messinian Salinity Crisis was developed
(Yesin [Esin] et al., 1986, 1987). In recent years, a model describing the flow of freshwater
from the Black and Caspian seas into the Mediterranean based on new geological material has
been proposed (Garcia-Castellanos et al., 2009). A model for the formation and subsequent
disappearance of the Paratethys seas was also recently presented (Esin et al., 2016). In the
present report, these processes are shown in their geologic sequence, and their mutual
influence is considered, taking into account the action of physical laws.
