Abstract

The geodynamic evolution of the Mediterranean is controlled by Cenozoic convergence between the African and Eurasian plates (Figure 1). This convergence was accommodated by closure and subduction of the Tethys Ocean and development of the Alpine crustal accretionary wedge. The geodynamic evolution of the Mediterranean is also marked by opening of continental and oceanic basins above retreating slabs.
