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 platform architecture was achieved by integrating field mapping, petrography, biostratigraphy, satellite imagery analysis and delta C-13 chemostratigraphy. In contrast to previous interpretations, this study indicates that: (i) the Great Bank of Guizhou transitioned during Early Triassic time from a low-relief bank to a platform with high relief above the basin floor (up to 600 m) and steep slope angles (preserved up to 50 degrees); and (ii) the oldest-known platform-margin reef of the Mesozoic Era grew along steep, prograding clinoforms in an outer-margin to lower-slope environment. Increasing platform relief during Early Triassic time was caused by limited sediment delivery to the basin margin and a high rate of accommodation creation driven by Indosinian convergence. The steep upper Olenekian (upper Lower Triassic) slope is dominated by well-cemented grainstone, suggesting that high carbonate saturation states led to syndepositional or rapid post-depositional sediment stabilization. Latest Spathian reef initiation coincided with global cooling following Early Triassic global warmth. The first Triassic framework-building metazoans on the Great Bank of Guizhou were small calcareous sponges restricted to deeper water settings, but early Mesozoic reef builders were volumetrically dominated byTubiphytes, a fossil genus of uncertain taxonomic affinity. In aggregate, the stratigraphic architecture of the Great Bank of Guizhou records sedimentary response to long-term environmental and biological recovery from the end-Permian mass extinction, highlighting the close connections among marine chemistry, marine ecosystems and carbonate depositional systems.

Structure of the crust and African slab beneath the central Anatolian plateau from receiver functions: New insights on isostatic compensation and slab dynamics Abgarmi, Bizhan; Delph, Jonathan R.; Özacar, Atilla Arda; Beck, Susan L.; Zandt, George; Sandvol, Eric; TÜRKELLİ, NİYAZİ; Biryol, C. Berk (Geological Society of America, 2017-11-01) 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.
The effects of subduction termination on the continental lithosphere: Linking volcanism, deformation, surface uplift, and slab tearing in central Anatolia Delph, Jonathan R.; Abgarmi, Bizhan; Ward, Kevin M.; Beck, Susan L.; Özacar, Atilla Arda; Zandt, George; Sandvol, Eric; TÜRKELLİ, NİYAZİ; Kalafat, Dogan (Geological Society of America, 2017-11-01) 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 impo...
Post-paleogene stress distribution in the Bartın-Ulus-Safranbolu Basins, Western pontides, Turkey Bengü, Emre; Rojay, Fuat Bora; Department of Geological Engineering (2017) The thesis addresses the post-Paleogene tectonic evolution of the Bartın-UlusSafranbolu basins in Western Pontides. The study area is bounded by Black Sea from north, Sünnice Massif from west, Kargı Massif from east, and by Cretaceous ophiolitic mélanges and the North Anatolian Fault from south. These basins are separated from each other by the two main faults, namely, Bartın and Karabük faults. Four structural domains are defined, based on lithostratigraphic differences and bounding major faults, to figure...
Modelling long term morphological change using XBeach Söğüt, Erdinç; Yalçıner, Ahmet Cevdet; Güler, Işıkhan; Department of Civil Engineering (2014) In this study, the XBeach Model, a two-dimensional depth averaged coupled hydrodynamic and morphologic numerical model, is used to determine the long-term behaviour of sediment transport process and morphological changes in Yumurtalık region in Adana, Turkey. Firstly, general information about the types of sediment transport processes and available coastal numerical models is given. Secondly, the structure of XBeach model, the boundary conditions and the model parameters that need to be defined are briefly ...
