It is tectonically imbricated along S-directed thrust faults between Paleozoic, continental-basement rocks of the Devrekani Massif (Eurasia) to the north, and late Triassic–early Cretaceous subduction-accretion complexes (Tethys) to the south. The ~5-km-thick crustal lithologies in the ophiolite are crosscut by WNW–ESE–oriented, extensional ductile–brittle shear zones and normal faults, which display hydrothermal mineralization and seafloor alteration effects. The WNW–ESE–striking sheeted dikes and these extensional fault systems indicate a NNE–SSW seafloor spreading direction during the magmatic evolution of the ophiolite. The U–Pb zircon dating of a gabbro has revealed a concordant age of 168.7±2.1 Ma, which represents the timing of the igneous construction of the ophiolite. Sandstone units in the ~3-km-thick turbiditic sedimentary cover of the ophiolite contain Paleo-Archean, Neo-Archean and Proterozoic detrital zircons that were likely derived from the Ukraine Shield and the East European Platform. These ages indicate a proximal position of the Kure basin to Eurasia during its development and the Kure ophiolite represents a Middle Jurassic continental backarc basin ophiolite with a Eurasian affinity. 2017-01-11 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1484129383372576 http://rave.ohiolink.edu/etdc/view?acc_num=miami1484129383372576 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
