The Black Sea Basin consists of two deep sub-basins (the West Black Sea BasinWBS and the East Black Sea Basin EBS) that are separated by the mid–Black Sea Ridge—an NW trending basement uplift [1]. The origin of the Black Sea and its evolution are still a matter of...

Ophiolitic rocks in the southeastern part of the Zagros Orogenic Belt can be separated from southwest to northeast, into two groups: the Neyriz ophiolites and the Naien–Shahrebabak–Baft ophiolites. The southeast sector of Sanandaj-Sirjan wasdelimited by the two nearly synchronous ophiolitic belts in its southwestern and northeastern margins. In this study, new ophiolitic formation models were u...

there are three different basic dykes in the northeast of golpayegan area, central part of sanandaj-sirjan zone (ssz) including: mylonitic gabbros (group 1), alkali dioritic-basanitic dykes (group 2) and alkali monzogabbroic to monzodioritic dykes (group 3). group 2 and 3 cut post-collisional rocks and are related to after subduction processes of neo-tethys. geochemistry characteristic of studi...

As an important tectonic unit of Eastern Tethyan domain, Sanjiang orogenic belt started from the expansion, subduction, subtraction and closure Paleozoic Paleo-Tethys Ocean, went through opening Neo-Tethys Ocean subduction collision process Indian continent ended in Himalayan comprehensive intracontinental convergence uplift orogeny, forming a giant composite composed several island arc belts s...

The Gangdese magmatic rocks of the southern Lhasa terrane, are generally thought to be an important window witness formation and evolution Neo-Tethys oceanic opening, subduction, closure, India-Eurasian continental collision. We investigated a new occurrence granodiorite in Nuocang district western Gangdese, conducted series analyses on their petrology, chronology, geochemistry. granodiorites h...
