The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...

Triassic eclogite and blueschist facies rocks occur as a thrust sheet, 25-km long and over 2-km thick, in an Eocene fold-andthrust belt in northwest Turkey along the İzmir–Ankara suture. The thrust sheet consists mainly of metabasites with minor marble, phyllite and metachert, and rare lenses of serpentinite. The common blueschist facies mineral assemblage in the metabasites is sodic amphibole ...

The structure and lithological sequences of ophiolites provide critical information for reconstructing their tectonic setting thus, the history paleo-oceanic basins in which they formed. Our systematic mapping three best-preserved massifs Xigaze ophiolite from middle segment Yarlung Zangbo Suture Zone (YZSZ) South Tibet, revealed a nearly intact ophiolitic sequence that has largely escaped empl...

Abstract The Beishan orogen is part of the Neo-proterozoic to early Mesozoic Central Asian Orogenic System in central Asia that exposes ophiolitic complexes, passive-margin strata, arc assemblages, and Precambrian basement rocks. To better constrain tectonic evolution orogen, we conducted field mapping, U-Pb zircon dating, whole-rock geochemical analysis, Sr-Nd isotopic analysis. new results, w...

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...

A Cretaceous paleo-accretionary wedge, the Ashin Complex, now exposed along Zagros suture zone in southern Iran, exhibits mafic, metasedimentary and ultramafic lithologies. Field, geochemical petrological observations point to an anomalous high-temperature event that gave rise formation of peritectic (trondhjemitic) melts associated with restitic garnet-bearing amphibolites. Lu-Hf isotopic dati...

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...

New structural data have been collected in the high-pressure meta-ophiolites exposed Lanzo Valleys (i.e., Ophiolite, LVO) and tectonically overlying continental crust of Dora-Maira Gran Paradiso massifs Western Alps. Detailed geological mapping analysis carried out south-western sector LVO Upper Viù Valley) allow to distinguish four ductile deformation phases, corresponding subduction-related D...
