Abstract We present new Sr-Nd-Pb-Hf isotopic data on mafic lavas from the Sivas, Develida?, Erciyes, and Erkilet volcanic complexes in central Turkey Tendürek eastern to evaluate mantle sources for volcanism context of geodynamic evolution Anatolian microplate. Early Miocene through Quaternary Western Anatolia latest activity Central were dominated by contributions two distinct source regions: ...

Extrapolation of the age distribution of oceanic lithosphere has played a significant role in assessments of variations in global mean spreading rate, global mean ocean basin depth, and implications for global mean sea level. Subduction has already removed 50% of oceanic lithosphere younger than 55.7Ma, making some level of extrapolation a necessary part of global plate reconstructions. An area...

The Kızıldağ (Hatay) ophiolite in southern Turkey represents a complete, although fault-dissected, remnant of oceanic lithosphere that formed within the South Tethyan ocean during late Cretaceous. forms part Upper Cretaceous belt which includes Troodos (Cyprus), Baer-Bassit (Syria), Amanos (S Tukey), S Iran and Semail (Oman) ophiolites. Ion-probe (SIMS) dating seven samples crustal rocks (cumul...

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...

Tsunami waves are the most underrated hazard affecting the life near coastal belts. With socio-economic developments in coastal region results in more hazardous from tsunami. The hazard assessment of tsunami is highly vital. The Makran region is exceptional in closure zone of Tethys; it is only segment east of the Mediterranean and west of Andaman arc in which subduction of oceanic lithosphere ...

India's northward flight and collision with Asia was a major driver of global tectonics in the Cenozoic and, we argue, of atmospheric CO(2) concentration (pCO(2)) and thus global climate. Subduction of Tethyan oceanic crust with a carpet of carbonate-rich pelagic sediments deposited during transit beneath the high-productivity equatorial belt resulted in a component flux of CO(2) delivery to th...
