Two main thrust slices in the Camdag area ( NW Anatolia), were informally named the Southern and Northern Camdag units. New micropaleontological and palynological data about the Ordovician, Silurian and Devonian in the Northern Camdag have allowed a better understanding of the early Palaeozoic evolution of this critical area between the Istanbul Terrane in the west and the Zonguldak Terrane in the east. The Middle Ordovician age obtained from the conodont-bearing limestone band within the Aydos formation in this study is in agreement with the data from the Zonguldag Terrane. Acritarch evidence suggests a Late Ordovician age of the upper part of Aydos formation.

The Istranca Crystalline Complex in NW Anatolia and SE Bulgaria includes structural units that differ in lithostratigraphy, metamorphism, age and structural position. They are collectively named as the "Istranca nappes" comprising from bottom to top the Sarpdere, Mahyadag. and Dogankoy Nappes. The Sarpdere Nappe consists of Lower Triassic arkosic metasandstones with slate interlayers, followed by Middle to Upper Triassic carbonates and an alternation of Upper Triassic clastics and carbonates. The Mahyada. g...
New zircon U-Pb LA-ICP-MS ages and Hf isotope data from the Central Pontides (Turkey): Geological and geodynamic constraints
ÇİMEN, OKAY; Göncüoğlu, Mehmet Cemal; Simonetti, Antonio; Sayıt, Kaan (2018-05-01)
The Central Pontides in northern Anatolia is located on the accretionary complex formed by the closure of Neotethyan Intra-Pontide Ocean between the southern Eurasian margin (Istanbul-Zonguldak Terrane) and the Cimmerian Sakarya Composite Terrane. Among other components of the oceanic lithosphere, it comprises not yet well-dated felsic igneous rocks formed in arc-basin as well as continent margin settings. In-situ U-Pb age results for zircons from the arc-basin system (tiangaldag Metamorphic Complex) and th...
Application of the coupled model to the Somme river basin
KORKMAZ, SERDAR; Ledoux, Emmanuel; Onder, Halil (2009-03-15)
Hydrological modeling of the Somme river basin situated in the north of France was made with special emphasis on the stream-aquifer interaction. Due to immense groundwater storage in the chalk aquifer, a damaging flood took place in the basin in spring 2001. To best represent the phenomena occurring in the basin, the coupled model also known as MODCOU was selected to be applied to this particular basin. The whole model structure consists of several components, namely, surface model, groundwater model, unsat...
An approach to paleoclimatic conditions for Devonian (upper Lochkovian and middle Givetian) ironstone formation, NW Anatolian carbonate platform
Yılmaz, İsmail Ömer; Göncüoğlu, Mehmet Cemal (2015-01-01)
Lower-middle Devonian iron-bearing successions were studied along 2 measured stratigraphic sections in the Camdag region of NW Anatolia. Ironstones in the upper part of the Findikli Formation in Kabalakdere are characterized by alternating red and green mudstones and sandstones at the bottom, followed by a series of dolomite, dolomitic limestone with oolitic ironstones, and chamositic mudstones at the top. Conodonts from these carbonates indicate the delta-pesavis zones of the late Lochkovian. The 12-to 45-...
Foraminiferal biostratigraphy and sequence stratigraphy across the mid-Carboniferous boundary in the Central Taurides, Turkey
Atakul-Ozdemir, Ayse; Altıner, Demir; Altıner, Sevinç; Yılmaz, İsmail Ömer (Springer Science and Business Media LLC, 2011-10-01)
The Aladag Unit is one of the main tectonic units in the Tauride Belt, located in southern Turkey. It includes a continuous Paleozoic carbonate sequence encompassing the mid-Carboniferous boundary, with outcrops being especially well exposed in the Hadim region. The boundary succession lithology is mainly composed of carbonates with intercalated quartz arenitic sandstone layers. Based on foraminifers, four biostratigraphic zones have been defined in the interval from the Upper Serpukhovian to the Lower Bash...
