A tsunamigenic sediment layer has been discovered in fluvio-alluvial sequences on the northern coast of the Marmara Sea, northwestern Turkey. The layer consists of unsorted silty coarse sand including terrestrial molluscs and charcoal fragments. The AMS radiometric ages of the shells have been estimated at around BC 400, AD 300, AD 400, and AD 1000. We propose that a tsunami occurred in the Marmara Sea in the middle of 11th century and invaded the fluvial plains. The older fossils were derived from the underlying horizons, and it is probable that buoyant materials such as terrestrial molluscs and charcoals were isolated from liquefied sediments during submarine sliding. Slope failure of coastal blocks triggered by fault movement generated tsunamis, which might have transported floating materials to the backshore.

The Sarikavak Tephra, Galatea, north central Turkey: a case study of a Miocene complex plinian eruption deposit Schumacher, R; Mues-Schumacher, U; Toprak, V (2001-12-01) The Sarikavak Tephra from the central Galatean Volcanic Province (Turkey) represents the deposit of a complex multiple phase plinian eruption of Miocene age. The eruptive sequence is subdivided into the Lower-, Middle-, and Upper Sarikavak Tephra (LSKT, MSKT, USKT) which differ in type of deposits, lithology and eruptive mechanisms.
Upper slope sediment waves in the Cilician Basin, northeastern Mediterranean Ediger, V; Velegrakis, AF; Evans, G (2002-12-15) Large sediment waves have been observed within the upper slope deposits of the Cilician Basin (northeastern Mediterranean), at the interfluve between two submarine canyons present offshore of the Mersin Shelf. There are several generations of sediment waves stacked within the sedimentary sequence, with the most recent bedforms found on the seabed in an area consisting of fine-grained sediments. The surficial sediment wave field, estimated to cover an area of similar to55 km(2), is found at water depths betw...
The Tarakli Flysch in the Boyali area (Sakarya Terrane, northern Turkey): Implications for the tectonic history of the IntraPontide suture zone Catanzariti, Rita; Ellero, Alessandro; Göncüoğlu, Mehmet Cemal; Marroni, Michele; Ottria, Giuseppe; Pandolfi, Luca (2013-11-01) In the Boyali area, northern Turkey, the tectonic units of the Istanbul-Zonguldak Terrane and the IntraPontide suture zone are thrust over the deposits at the top of the Sakarya Terrane, known as Tarakli Flysch. It consists of Early Maastrichtian-Middle Paleocene turbidite and mass-gravity deposits, whose source mainly corresponds to the Istanbul-Zonguldak Terrane, and, with a lesser extent, to the IntraPontide suture zone. These deposits were sedimented in a foredeep basin developed during the convergence ...
Development and lipid storage in Calanus euxinus from the Black and Marmara seas: Variabilities due to habitat conditions Svetlichny, LS; Kıdeyş, Ahmet Erkan; Hubareva, ES; Besiktepe, S; Isinibilir, M (2006-01-01) Oil sac volume, gonad size and moulting patterns were investigated in the copepod Calanus euxinus inhabiting deep and shallow zones of the Black Sea and penetrating into the Marmara Sea. In summer the C. euxinus population in deep layers of the Black Sea was dominated by pre-diapause and diapausing postmoult copepodite stage V (CV) with small sexually undifferentiated gonads and mean lipid content of 14.1 +/- 6.0% of body volume. The lipid content of deep-living females was 7.2 +/- 4.2% of body volume. At t...
A Miocene onset of the modern extensional regime in the Isparta Angle: constraints from the Yalva double dagger Basin (southwest Turkey) Koc, Ayten; Kaymakcı, Nuretdin; van Hinsbergen, Douwe J. J.; Vissers, Reinoud L. M. (2016-01-01) The pre-Neogene Tauride fold-and-thrust belt, comprising Cretaceous ophiolites and metamorphic rocks and non-metamorphic carbonate thrust slices in southern Turkey, is flanked and overlain by Neogene sedimentary basins. These include poorly studied intra-montane basins including the Yalva double dagger Basin. In this paper, we study the stratigraphy, sedimentology and structure of the Yalva double dagger Basin, which has a Middle Miocene and younger stratigraphy. Our results show that the basin formed as a ...
