The Neotethyan convergence system between the Eurasian plate and Tauride-Anatolide platform in NE and Central Turkey possess well-preserved igneous rocks characterizing different stages of convergence. The convergence system includes (1) Senonian pre-collision (subduction) (2) Late Cretaceous syn-collision and (3) post-collisional stages consisting of subdivisions such as (1) Late Cretaceous I-type, CALK hybrid magmatism (11) Late Cretaceous to Paleocene distensional-related, intracrustal A-type intrusives and (III) Middle-Upper Eocene post-collisional, extensional-related, A-type intrusives. The pre-, syn- and post-collisonal granitoids seem to be associated with their proper mineralization in terms of magma genesis and wall-rock maintained by different geodynamics. After amalgamation, sedimentation in Oligo-Miocene transpressional and Mio-Pliocene transtensional basins has induced the widespread sedimentary and volcano-sedimantary sequences accompanied the evaporite deposition in Central Turkey. The hydrothermal consequences of sequential convergence events are well recorded by temporarily and spatially associated mineral deposits in NE and Central Turkey.
