During Late Cretaceous–Mid-Eocene the Girne (Kyrenia) Range formed part of the northerly active continental margin of the southern Neotethys. Following Late Eocene–Late Miocene mainly deep-marine clastic deposition, the range was thrust southwards in a convergent (transpressional) stress regime during Late Miocene (Messinian)–earliest Pliocene time. Sinistral transpression is most evident near the front of the range in the east and in several segments, implying strain compartmentalization. The range was relatively quiescent during Early–Mid Pliocene, followed by strong c. east–west-trending uplift during Late Pliocene–Pleistocene. Further south, the east–west Dar Dere (Ovgos) lineament was active as a north-down extensional (or transtensional) fault zone during Oligocene–Mid-Miocene. Sinistral strike-slip/transpression followed during Late Miocene, followed by strike-slip at least during Late Pliocene–Pleistocene. The latest Miocene–earliest Pliocene thrusting/oblique convergence reflects closure of the southern Neotethys and tightening of the suture between the Arabian (North African) and Turkish (Eurasian) continents. Collision-related uplift of the Girne (Kyrenia) Range and the Troodos Massif further south took place from Late Pliocene time onwards. The Dar Dere (Ovgos) lineament is interpreted as a terrane boundary that was reactivated related to westward tectonic escape of Anatolia during Neogene–Recent time. The structure as a whole reflects regional diachronous continental collision.

Geological Development of Anatolia and the Easternmost Mediterranean Region
Anatolia and the easternmost Mediterranean region, especially Turkey, Cyprus and northern Syria, represent an excellent natural laboratory for the study of fundamental geological processes (e.g. rifting, seafloor spreading, ophiolite genesis and emplacement, subduction, exhumation and collision). Their interaction has created an intriguing array of deep-sea basins, microcontinents and suture zones.
The volume’s 22 papers include a large amount of new field-based information (much of it multidisciplinary and the product of teamwork). After an overview, the volume is divided into four sections: Late Palaeozoic–Early Cenozoic of the Pontides (northern Turkey); Late Palaeozoic–Early Cenozoic of the Taurides–Anatolides (central and southern Turkey); Late Cretaceous–Pliocene sedimentary basins and structural development (central Anatolia to the Mediterranean); Late Miocene–Recent Neotectonics (southern Turkey, Cyprus and northern Syria).
The volume will interest numerous academic researchers, those concerned with resources (e.g. hydrocarbons; mineral deposits) and also hazards (e.g. earthquakes), as well as advanced undergraduate and postgraduate students.
