The recent geodynamics of the Arabo-Mediterranean domain are dominated by the progressive closure of remnant oceanic basins squeezed between the Eurasian margin and the Nubia （Africa） and Arabia plates. Various stages of consumption have been reached from Gibraltar to Oman, ranging from incipient inversion （e.g. the North African margin）, to subduction （Mesozoic basins of the Eastern Mediterranean） and collision （e.g. the Zagros or Caucasus belts）. Convergence is accompanied by deformation of both Eurasian and African margins, mostly as diffuse compression, but also as extension in short-lived basins and motion of blocks escaping towards the remnant oceanic spaces. The resulting kinematic pattern is quite complex. Western Mediterranean domain is merely accommodating the slow convergence of Nubia, whereas the still high convergence of Arabia in the Eastern domain has pushed Anatolia sideways, which is now laterally escaping to the west-southwest.展开更多
