Neotectonic aspects of the northern margin of the Adana-Cilicia submarine basin, NE Mediterranean

Abstract

The sedimentary basins that dominate the north-eastern Mediterranean (Adana-Cilicia basins in the west and Iskenderun basin in the east) are located on the flanks of a partly submerged positive structure (a part of the Africa-Eurasia convergence zone) along which strike-slip faults are evident. This study summarizes the findings of two seismic surveys carried out in the AlanyaMersin offshore region. Some 850 km of geophysical survey lines were compiled on these cruises. Based on the results determined from these surveys, the north and central part of Adana-Cilicia basin can be subdivided into eastern, central and western structural sub-basins separated by the Ecemiş fault complex in the east and the Anamur-Kormakiti structural high in the west at the same time. Results of this study also indicate that Ecemiş and Anamur-Kormakiti faults are active. Late Miocene regional compression was responsible for the compartmentation of this complex into the present arrangement and has initiated the rotational regime which has governed subsequent tectonic developments, notably the extensional behaviour of the NE-SW trending Ecemiş and Anamur-Kormakiti faults and the transpressive behaviour of the NNE-SSW trending border fault complex.

Sedimentary evidence for late Messinian uplift of theSEmargin of the Central Anatolian Plateau: Adana Basin, southern Turkey

“…On the basis of different seismic interpretations, the late Miocene–Pliocene kinematics of the fault have been defined as either predominantly strike‐slip (Aksu et al . ) or predominantly extensional (Ozel et al ., ). Nonetheless, we have found no indication in the seismic lines (e.g.…”

Depositional architecture and sequence stratigraphy of Pleistocene coarse-grained deltas along the Ligurian coast (Italy)

“…Coastal marine depositional systems, and in particular, deltas are useful to determine changes in relative sea-level as the result of the interplay between tectonics, eustasy, climate, basin physiography and sediment supply. Ancient alluvial coarse-grained deltas have been intensively studied in many areas (Bardaji et al 1990;Lopez-Blanco et al 2003;Breda et al 2007;Di Celma and Cantalamessa 2007;Ozel et al 2007;Sáez et al 2007;Longhitano 2008;Backert et al 2010;Di Celma et al 2010;Fidolini et al 2013). The identification of each depositional environment within the deltaic system (delta plain, delta front, delta slope and offshore-transition) and their sedimentological characteristics is necessary for the reconstruction of the evolution of the delta and the stacking pattern of these various elements are necessary for the interpretation of the influence of tectonics and eustasy.…”
