Abstract: Aktepe-Gökdere region consists of magmatic ,and sedimentary rocks ranging in age through Early Cretaceous to Tertiary. Emplacement of ultramafic magma took place during early stages of Upper Cretaceous in the region.It is thought that the magma was poured out in a wet, flyseh-like sedimentary matrix (Ağıltepe Unit) ,and mixedup with it, thus yielding a para-autochthonous melange structure. This structure became more chaotic during west to easttransportation due to tectonic forces of Alpine orogeny in which orogenic gravity ,and thrusting were also involved.Thrusting of ophiolitic melange over Paleocene ,and younger formations is obscured by tuffaceous cover of Miocene age ,and further tectonic movements.
