We discuss the assembly and tectonochronology of Cycladic Blueschist Unit (CBU) in central Aegean Sea region, Greece, as a composite, subduction-related, high-pressure (blueschist to eclogite facies) stack nappes. Our work is based on review geochronologic data from islands Tinos, Syros Sifnos. In addition, we present large set 34 new, internally consistent Rb-Sr multimineral isochron age these...

We describe a singular structure in Upper Cretaceous rocks of the Eaux-Chaudes massif western Pyrenees, consisting kilometre-scale fold nappe with sheared overturned limb. High ductile strain attests deformation style rarely reported for alpine and peak temperature carbonates is estimated by Raman spectroscopy carbonaceous material palaeothermometry lower greenschist facies (>300°C). The normal...

The collision of Baltica and Laurentia during the Caledonian Orogeny happened at c. 400–420 Ma. However, subduction processes also took place before this main collisional phase tectonic history these is still not fully resolved. Seve Nappe Complex in Sweden has recorded earlier phases. Norrbotten (North Swedish Caledonides) comprises four superimposed nappes emplaced by eastward thrusting (from...

Abstract The Late Palaeozoic–Early Mesozoic Tethyan development of the Eastern Mediterranean region remains debatable, especially in Turkey, where alternative northward and southward subduction hypotheses are proposed. Relevant to this debate, new whole-rock geochemical data provided here for early Carboniferous (Late Tournaisian-Late Visean; c. 340–350 Ma) tuffaceous sedimentary rocks within Ç...
