“…Furthermore, Roveri et al (2014a, b) This revised Messinian scenario is described within the framework of a 3-stage stratigraphic model constructed mainly with observations from the marginal to intermediate basins exposed onshore in Sicily and in the Northern Apennines (CIESM, 2008;Roveri et al, 2014a, b). However, despite the extensive 'back-catalogue' of work on the Messinian stage (e.g., Roveri et al, 2014a), many studies from the easternmost extent of the Mediterranean have focussed on Cyprus (e.g., Robertson et al, 1995;Krijgsman et al, 2002;Kouwenhoven et al, 2006;Orszag-Sperber et al, 2006;Manzi et al, 2015) and adjacent ODP data (e.g., Blanc-Valleron et al, 1998;Pierre et al, 1998), with limited data from southern Turkey Darbaş and Nazik, 2010;Poisson et al, 2011;Cipollari et al, 2013;Faranda et al, 2013;Radeff et al, 2015). In this paper we focus on late Miocene and early Pliocene sediments of the Hatay Graben (southern Turkey), previously identified by Boulton et al ( , 2008 and Tekin et al (2010).…”

“…Stage 3 (5.55 -5.33 Ma) is thought to have been a period of complex water exchange between the Atlantic Ocean and Paratethys (Orszag-Sperber, 2006;Rouchy and Caruso, 2006;Roveri et al, 2008b), which resulted in selenite and cumulate gypsum deposition in shallow marginal basins in the central and eastern Mediterranean (i.e., Sicily and Cyprus). The Upper Gypsum deposits are superficially similar to the PLG deposits, yet facies analysis indicates formation in very shallow water (Manzi et al, 2007(Manzi et al, , 2009Lugli et al, 2008;Roveri et al, 2014a).…”

“…Furthermore, distinctively low Sr isotope values (compared to oceanic values) have been measured from both the gypsum and fossils of these sections, indicating substantial freshwater input (Flecker and Ellam, 2006;Roveri et al, 2014a, b). By contrast, in northern and western marginal basins evaporite-free clastics formed in shallow to deep-water environments with characteristic brackish to fresh water fauna often referred to as the 'Lago Mare' biofacies (Ruggieri, 1967;Bassetti et al, 2004;Orszag-Sperber, 2006;Grossi et al, 2008, Roveri et al, 2008bPopescu et al, 2015).…”

The Hatay Graben is one of three easternmost basins in the Mediterranean that preserve sediments that span the Miocene-Pliocene boundary, including gypsums from the Messinian Salinity Crisis (MSC). Here we integrate existing data and present new sedimentological and micropalaeontological data to investigate the palaeoenvironments of late Miocene to early Pliocene deposits and place this important area into a regional stratigraphic framework. Six sections are described along a ~ W -E transect illustrating the key features of this time period. Late Miocene (Pre-MSC) sediments are characterised by open marine marls with a benthic foraminiferal fauna suggestive of water depths of 100 -200 m or less. Primary lower gypsum deposits are determined to be absent from the graben as sedimentological and strontium isotopes are characteristic of the resedimented lower gypsums. The intervening Messinian erosion surface is preserved near the basin margins as an unconformity but appears to be a correlative conformity in the basin depocentre. No Upper Gypsums or 'Lago-Mare' facies have been identified but available data do tentatively suggest a return to marine conditions in the basin prior to the Zanclean boundary. Sediments stratigraphically overlying the Messinian gypsums and marls are coarse-grained sandstones from coastal and Gilbert-type delta depositional environments. The Hatay Graben is not only strikingly similar to Messinian basins on nearby Cyprus but also to the overall model for the MSC, demonstrating the remarkable consistency of palaeoenvironments found in marginal basins across the region at this time. This research also raises questions as to the timing of the Mediterranean reflooding and the significance of the widespread mega-breccias of the resedimented gypsum deposits.

“…In the Messinian this gateway was strongly restricted because of major sea level fall that was accompanied by salinity crises in the region. Conditions similar to today were established by the Pliocene transgression [e.g., Orszag-Sperber, 2006;Popov et al, 2006].…”

Oceanographic and climatic evolution of the Miocene Mediterranean deduced from Nd, Sr, C, and O isotope compositions of marine fossils and sediments

et al. 2008

[1] Isotopic compositions of marine sediments and fossils have been investigated from northern basins of the Mediterranean to help constrain local oceanographic and climatic changes adjacent to the uplifting Alps. Stable C and O isotope compositions of benthic and planktonic foraminifera from the Umbria-Marche region (UMC) have an offset characteristic for their habitats and the changes in composition mimic global changes, suggesting that the regional conditions of climate and the carbon cycle were controlled by global changes. The radiogenic isotope composition of these fossil assemblages allows recognition of three distinct periods. In the first period, from 25 to 19 Ma, high e Nd values and low 87 Sr/ 86 Sr of sediments and fossils support intense tectonism and volcanism, related to the opening of the western Mediterranean. In the second period, from 19 to 13 Ma the 87 Sr/ 86 Sr ratio of Mediterranean (UMC) deviate from the global ocean, which is compatible with rapid uplift of the hinterland and intense influx of Sr from Mesozoic carbonates of the western Apennines. This local control on the seawater was driven by a humid and warm climate and indicates restricted exchange of water with the global ocean. Generally, the e Nd values of the fossils are very similar to those of Indian Ocean water, with brief periods of a decrease in the e Nd values coinciding with volcanic events and maybe sea level variation at 15.2 Ma. In the third period, from 13 to 10 Ma the fossils have 87 Sr/ 86 Sr similar to those of Miocene seawater while their e Nd values change considerably with time. This indicates fluctuating influence of the Atlantic versus the Paratethys and/or locally evolved seawater in the Mediterranean driven by global sea level changes. Other investigated localities near the Alps and from the ODP 900 site are compatible with this oceanographic interpretation. However, in the late early Miocene, enhanced local control, reflecting erosion of old crustal silicate rocks near the Alps, results in higher 87 Sr/ 86 Sr.Citation: Kocsis, L., T.
