The Adana-Cilician basin formed by interaction between the African, Arabian, and Anatolian plates. The basin has been filled asymmetrically from the north and northeast with the northeastern extremity having been completely filled to form the Adana basin beneath the plain of the Seyhan delta. There is no direct borehole evidence from the submarine areas, but coastal boreholes have revealed the presence of at least 6 km of Neogene sediment. The Burdigalian-Serravalian interval is dominated by turbidites and deep-water shales in the center of the Adana basin, with shallow-water clastics and carbonates around the margins. A layer of Messinian evaporite appears to underlie much of the basin. The Serravalian-Pleistocene sedimentation was dominated by shallow marine and terrestrial sedimentation in the Adana basin, the only part known. Today, the Turkish rivers have built up several deltaic complexes. Quaternary sea level and climatic changes and the movement of river mouths have complicated the pattern of shelf sediments. Away from the immediate vicinity of river mouths, the sediments are rich in the remains of macrobenthos and microbenthos, and on tectonically controlled highs coralline algal mounds occur. The sediments of the deeper water areas (/approx/ 1,000 m) show evidence of downslope movement of shelf sediments and anoxic periods, and they contain an impoverished molluscan and foraminiferal fauna. Sediment dispersal appears to have been confined by submarine tectonic barriers. Continuous uplift and faulting along some margins together with flow of evaporites away from the depocenters on the Turkish coast appear to be actively affecting the most recently deposited sediments.

Seismic attenuation tomography of the Sn phase beneath the Turkish-Iranian Plateau and the Zagros mountain belt Kaviani, Ayoub; Sandvol, Eric; Ku, Wenfei; Beck, Susan L.; Türkelli, Niyazi; Özacar, Atilla Arda; Delph, Jonathan R. (2022-08-01) The Turkish-Iranian Plateau and the Zagros highlands are among the most prominent physiographic features in the Middle East and were formed as a result of continental collision between the Arabian and Eurasian plates. To better understand the nature of the lithospheric mantle and the origin of the observed seismic anomalies in this region, we investigated seismic attenuation of the uppermost mantle by detailed measurements of the quality factor of the Sn seismic phase (Sn Q). To that end, we collected a lar...
Novel insights on demographic history of tribal and caste groups from West Maharashtra (India) using genome-wide data Debortoli, Guilherme; Abbatangelo, Cristina; Ceballos, Francisco; Fortes-Lima, Cesar; Norton, Heather L.; Ozarkar, Shantanu; Parra, Esteban J.; Jonnalagadda, Manjari (Springer Science and Business Media LLC, 2020-6-22) The South Asian subcontinent is characterized by a complex history of human migrations and population interactions. In this study, we used genome-wide data to provide novel insights on the demographic history and population relationships of six Indo-European populations from the Indian State of West Maharashtra. The samples correspond to two castes (Deshastha Brahmins and Kunbi Marathas) and four tribal groups (Kokana, Warli, Bhil and Pawara). We show that tribal groups have had much smaller effective popul...
Palaeoenvironment and human interaction during the last 4k years in the dried lake sediments (amik lake, southern turkey): evidences of lake level changes El Ouahabi, Meriam; Hubert-ferrari, Aurelia; Auwera, Vander; Avşar, Ulaş; Karabacak, Volkan (2019-02-01) The Amik Basin in the Eastern Mediterranean region has been continuously occupied since 6000-7000 BC. The landscape has sustained with highly variable anthropic pressure culminating during the Late Roman Period when the Antioch city reached its golden age. The basin also sustained a high seismic activity (M≥7) as it is a releasing step-over along the Dead Sea Fault. The study focuses on the sedimentary record of the Amik Lake occupying the central part of the Basin. Our objective is to constrain major paleo...
Superficial deep-water sediments of the Eastern Marmara Basin Evans, G.; Erten, H.; Alavi, S. N.; Von Gunten, H. R.; Ergin, M. (Springer Science and Business Media LLC, 1989-3) Superficial sediments (top ∼ Im) of the Eastern Mediterranean Basin, Sea of Marmara, Turkey accumulated rapidly (0.087 ± 0.012 g/cm2 · y) by hemipelagic sedimentation with only limited amounts of gravity flow or bottom current action under low oxygenated but not anoxic conditions. They have restricted faunas, relatively higher organic carbon (1–1.8%) and lower calcium carbonate (14–20%) contents than other Eastern Mediterranean Basin sediments. Sedimentation shows little change over the last millenium excep...
Recent sedimentation on the shelf and upper slope in the Bay of Anamur, southern coast of Turkey Alavi, Seyed Naeim; Ediger, Volkan S.; Ergin, Mustafa (Elsevier BV, 1989-9) Sedimentological studies, supported by Uniboom profiles and sonographs, of surface sediments from a part of the narrow southern shelf of Anatolia, indented by the head of a submarine canyon and partly covered by meadows of macrophytobenthos, revealed abrupt lateral and vertical variations in the Holocene sedimentary facies. These variations have essentially been controlled by the migration of depocentres, (palaeo-) topography of the shelf and an overall decrease in the rate of fluviatile sediment supply in ...
