We investigated the geochemical features of the fluids circulating over the Amik Basin (SE Turkey-Syria border), which is crossed by the Northern extension of the DSF (Dead Sea Fault) and represents the boundary area of three tectonic plates (Anatolian, Arabian and African plates). We collected 34 water samples (thermal and cold from natural springs and boreholes) as well as 8 gas samples (bubbling and gas seepage) besides the gases dissolved in the sampled waters. The results show that the dissolved gas phase is a mixture of shallow (atmospheric) and deep components either of mantle and crustal origin. Coherently the sampled waters are variable mixtures of shallow and deep ground waters, the latter being characterised by higher salinity and longer residence times. The deep groundwaters (from boreholes deeper than 1000 m) have a CH4-dominated dissolved gas phase related to the presence of hydrocarbon reservoirs. The very unique tectonic setting of the area includes the presence of an ophiolitic block outcropping in the westernmost area on the African Plate, as well as basalts located to the North and East on the Arabic Plate.


Historical and pre-historical tsunamis in the Mediterranean and its connected seas: Geological signatures, generation mechanisms and coastal impacts

The origin of tsunamis in the Mediterranean region and its connected seas, including the Marmara Sea, the Black Sea and the SW Iberian Margin in the NE Atlantic Ocean, is reviewed within the geological and seismotectonic settings of the region. A variety of historical documentary sources combined with evidence from onshore and offshore geological signatures, geomorphological imprints, observations from selected coastal archeological sites, as well as instrumental records, eyewitnesses accounts and pictorial...
Geological and Geochemical Evolution of the Quaternary Suphan Stratovolcano, Eastern Anatolia, Turkey: Evidence for the Lithosphere-Asthenosphere Interaction in Post-Collisional Volcanism
Özdemir, Yavuz; Güleç, Nilgün Türkan (Oxford University Press (OUP), 2014-01-01)
The Suphan stratovolcano is one of the major Quaternary eruption centers of post-collisional volcanism in eastern Anatolia, located in the zone of convergence between the Arabian and the Anatolian plates. We document the geological and geochemical evolution of Suphan in terms of volcanostratigraphy, geochronology (Ar-40-Ar-39), isotope composition (Sr, Nd, Pb) and bulk-rock geochemistry. Our new Ar-40-Ar-39 data, along with previously published K/Ar ages, indicate an age of 0 center dot 76-0 center dot 06 M...

Six box-cores, one boomerang core and one hundred sixty-six surface sediment samples recovered in the Sea of Marmara were analyzed in an attempt to establish the main controls on distribution and origin of trace metals within the oxic to suboxic basin of this sea.
Late quaternary sedimentation in the strait of bosporus: high-resolution seismic profiling
Alavi, Seyed Naeim; Okyar, Mahmut; Köse, Timur (Elsevier BV, 1989-10)
Uniboom profiling supported by borehole data in the southern part of the Bosporus revealed that close to its banks Holocene sediments are underlain by the faulted slopes of a valley cut in many places into the Palaeozoic bedrock. Away from the banks the sediments thicken and their boundary with the underlying Pleistocene deposits is defined by an erosional surface at about the 80 ms TWT. This surface marks the initiation of marine currents in the valley as its deeper parts began to be submerged in the late ...
Crustal velocity structure of Central and Eastern Turkey from ambient noise tomography
Warren, Linda M.; Beck, Susan L.; Biryol, C. Berk; Zandt, George; Özacar, Atilla Arda; Yang, Yingjie (Oxford University Press (OUP), 2013-09-01)
In eastern Turkey, the ongoing convergence of the Arabian and African plates with Eurasia has resulted in the westward extrusion of the Anatolian Plate. To better understand the current state and the tectonic history of this region, we image crust and uppermost mantle structure with ambient noise tomography. Our study area extends from longitudes of 32 degrees to 44 degrees E. We use continuous data from two temporary seismic deployments, our 2006-2008 North Anatolian Fault Passive Seismic Experiment and th...
