Southern North Sea Basin is one of the mature hydrocarbon basins in NW Europe and is shaped by a number of phases of tectonic deformations during the Phanerozoic. In addition, mobilization and halokinesis of thick Permian Zechstein Salt has enhanced and contributed to the deformation of the region since Triassic, which further complicated the geology of the region. The Friesland Platform, which is a stable platform area located in northern Netherlands, experienced the main deformation phases that Europe has been endured together with the deformation of Permian Zechstein salt. In this study a computer based 3D modeling has been carried out within the Friesland Platform with the use of 3D seismic and borehole data in order to delineate structural elements and geological development of the area with special emphasis on the salt tectonic deformation. The model was constructed by picking key horizons and major faults from the seismic sections in time domain and then migrated into depth domain. The stratigraphy of the area is correlated with horizons by well-seismic matching. The model includes major structures and seismostratigraphic units of Permian to recent, revealing salt and salt induced structures formed during the periods of active salt movements. Thick Zechstein salt layers deposited in N-S-oriented grabens and half grabens of South Permian Basin acted as the primary control for the location of salt diapirs and are reflected on the overburden without a direct continuation (unlinked) of the basement faults into the overburden. The mapped N-S oriented salt-cored anticline and a convergent conjugate transfer zone between a pair of segmented normal growth faults at the crest of the anticline are controlled by the ascent of the Zechstein salt.

Geological evolution of the gediz graben, sw turkey: temporal and spatial variation of the graben Çiftçi, Bozkurt N; Bozkurt, Erdin; Department of Geological Engineering (2007) Gediz Graben is a continental extensional basin filled with Neogene sediments. Its margins are controlled by active ~EW-trending fault systems with major system, in terms of total offset and duration of activity, located along the southern margin. The graben evolved as a half graben by the activity of the southern margin during the entire Miocene. Then, the northern margin-bounding structure initiated by PlioQuaternary to form the current configuration of the graben with an inherited asymmetry. The southern...
Rapid cooling history of a Neotethyan ophiolite: Evidence for contemporaneous subduction initiation and metamorphic sole formation PARLAK, OSMAN; Dunkl, Istvan; KARAOĞLAN, FATİH; Kusky, Timothy M.; Zhang, Chao; Wang, Lu; Koepke, Juergen; Billor, Zeki; Hames, Willis E.; ŞİMŞEK, EMRAH; Simsek, Gokce; ŞİMŞEK, TUĞÇE; Ozturk, Selena Ezgi (Geological Society of America, 2019-11-01) The Beywhir-Hoyran Nappes, including Mesozoic carbonate platform rocks, deepsea sediments, and ophiolite-related units, crop out extensively on the western limb of the Isparta Angle in the Central Taurides, Turkey. The ophiolite-related rocks are represented by variably serpentinized harzburgitic mantle tectonites, tectonically underlain by a subophiolitic metamorphic sole and melange. The harzburgitic mantle tectonites and metamorphic sole are intruded by undeformed isolated dikes. Protoliths of the metamo...
GEOLOGICAL AND GEOCHEMICAL EVIDENCE FOR A LATE CRETACEOUS CONTINENTAL ARC IN THE CENTRAL PONTIDES, NORTHERN TURKEY Ellero, Alessandro; Ottria, Giuseppe; Sayıt, Kaan; Catanzariti, Rita; Frassi, Chiara; Göncüoğlu, Mehmet Cemal; Marroni, Michele; Pandolfi, Luca (2015-01-01) In the Central Pontides (Northern Turkey), south of Tosya, a tectonic unit consisting of not-metamorphic volcanic rocks and overlying sedimentary succession is exposed inside a fault-bounded elongated block. It is restrained within a wide shear zone, where the Intra-Pontide suture zone, the Sakarya terrane and the Izmir-Ankara-Erzincan suture zone are juxtaposed as result of strike-slip activity of the North Anatolian shear zone. The volcanic rocks are mainly basalts and basaltic andesites (with their pyroc...
Sarackoy Volcanic Suite: implications for the subductional phase of arc evolution in the Galatean Arc Complex, Ankara, Turkey Kocyigit, A; Winchester, JA; Bozkurt, Erdin; Holland, G (Wiley, 2003-01-01) A sequence of upper Campanian volcanic rocks, hitherto considered as part of the Miocene calc-alkaline Galatean volcanic sequence, crops out near Sarackoy, 40 km north of Ankara. These volcanic rocks, unconformably overlain by Eocene nummulitic limestones, comprise thin flows and volcaniclastic deposits. They can be divided compositionally into three distinct subunits: (i) basal massive trachyandesitic volcaniclastic rocks with a thin flow at the top, overlain by (ii) mixed volcaniclastic rocks and thin amy...
Analysis of Plio-Quaternary deep marine systems and their evolution in a compressional tectonic regime, Eastern Black Sea Basin Sipahioglu, N. O.; Karahanoğlu, Nurkan; Altıner, Demir (Elsevier BV, 2013-05-01) Facies architecture of submarine fans and channel-levee complexes in the Eastern Black Sea Basin and their evolution from the Late Miocene until the present day are studied using a three-dimensional seismic data set covering an area of approximately 1161 km(2). The interpretation of the observations reveals the outcome of the changing interplay between rate of sedimentation and compressional tectonism in the area through time.
