Subduction beneath central Anatolia represents the transition between continuous subduction along the Aegean trench in the west and slab break-off and/or subduction termination at the Arabian-Eurasian collision zone in the east. Using recently collected seismic data from the Continental Dynamics-Central Anatolian Tectonics project alongside a newly developed approach to the creation of a 3D shear-velocity model from the joint inversion of receiver functions and surface-wave dispersion data, we can gain important insights into the character of the downgoing, segmenting African lithosphere and its relationship with the overriding Central Anatolian plate.


Structure of the crust and African slab beneath the central Anatolian plateau from receiver functions: New insights on isostatic compensation and slab dynamics

The central Anatolian plateau in Turkey is a region with a long history of subduction, continental collision, accretion of continental fragments, and slab tearing and/or breakoff and tectonic escape. Central Anatolia is currently characterized as a nascent plateau with widespread Neogene volcanism and predominantly transtensional deformation. To elucidate the present-day crustal and upper mantle structure of this region, teleseismic receiver functions were calculated from 500 seismic events recorded on 92 t...
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.
Tectonic geomorphology and Plio-Quaternary structural evolution of the Tuzgolu fault zone, Turkey: Implications for deformation in the interior of the Central Anatolian Plateau
Krystopowicz, Neil J.; Schoenbohm, Lindsay M.; Rimando, Jeremy; Brocard, Gilles; Rojay, Fuat Bora (Geological Society of America, 2020-10-01)
Situated within the interior of the Central Anatolian Plateau (Turkey), the 200-km-long Tuzgolu extensional fault zone offers first-order constraints on the timing and pattern of regional deformation and uplift. In this study, we analyze the morphometrics of catchments along the Tuzgolti range-front fault and the parallel, basinward Hamzali fault using a variety of measured morphometric indicators coupled with regional geomorphic observations and longitudinal profile analysis. In addition, we use field and ...
Lithospheric structural control on inversion of the southern margin of the Black Sea Basin, Central Pontides, Turkey
Espurt, Nicolas; Hippolyte, Jean-Claude; Kaymakcı, Nuretdin; SANĞU, ERCAN (GeoScienceWorld, 2014-02-01)
To illustrate the structural evolution of the Black Sea Basin in the context of Neotethyan subduction and subsequent continental collisions, we present the first lithosphere-scale, similar to 250-km-long, balanced and restored cross section across its southern continental margin, the Central Pontides. Cross-section construction and restoration are based on field, seismic-reflection, geophysical, and apatite fission-track data. The structure of the onshore Pontides belt is predominantly controlled by inverte...
Controls on carbonate platform architecture and reef recovery across the Palaeozoic to Mesozoic transition: A high-resolution analysis of the Great Bank of Guizhou
Kelley, Brian M.; Lehrmann, Daniel J.; Yu, Meiyi; Jost, Adam B.; Meyer, Katja M.; Lau, Kimberly; Altıner, Demir; Li, Xiaowei; Minzoni, Marcello; Schaal, Ellen K.; Payne, Jonathan L. (Wiley, 2020-10-01)
Carbonate platforms spanning intervals of global change provide an opportunity to identify causal links between the evolution of marine environment and depositional architecture. This study investigates the controls on platform geometry across the Palaeozoic to Mesozoic transition and yields new stratigraphic and palaeoenvironmental constraints on the Great Bank of Guizhou, a latest Permian to earliest Late Triassic isolated carbonate platform in the Nanpanjiang Basin of south China. Reconstruction of platf...
