Easternmost Mediterranean evidence of the Zanclean flooding event and subsequent surface uplift: Adana Basin, southern Turkey

Abstract

""\\"According to the literature, the Adana Basin, at the easternmost part of the Mediterranean. Basin in southern Turkey, records the Pliocene stage with shallow-marine to fluvial deposits.. Our micropalaeontological analysis of samples from the Adana Basin reveal Late Lago–Mare. biofacies with Paratethyan ostracod assemblages pertaining to the Loxocorniculina djafarovi. zone. Grey clays rich in planktonic foraminifera lie above the Lago–Mare deposits. Within the. grey clays, the continuous occurrence of the calcareous nannofossil Reticulofenestra zancleana. and the base of the Reticulofenestra pseudoumbilicus paracme points to an Early Zanclean age. (5.332–5.199 Ma). Both ostracod and benthic foraminifera indicate epibathyal and bathyal. environments. 87Sr\\\\\\\/86Sr measurements on planktonic and benthic foraminifera fall below the. mean global ocean value for the Early Zanclean, indicating potentially insufficient mixing of. low 87Sr\\\\\\\/86Sr Mediterranean brackish ‘Lago–Mare’ water with the global ocean in the earliest. Pliocene. We utilize the ages and palaeodepths of the marine sediments together with their modern. elevations to determine uplift rates of the Adana Basin of 0.06 to 0.13 mm a21 since 5.2–5.3 Ma. (total uplift of 350–650 m) from surface data, and 0.02–0.13 mm a21 since c. 1.8 Ma (total uplift. of 30–230 m) from subsurface data.. Supplementary material: Microphotographs of foraminifers, ostracods, and calcareous nannofossils,. plots of the calcareous nannofossil frequencies, occurrence of foraminifers and ostracods in. the study sections, results of Sr isotopic analysis, and a complete list of fossils are available at. www.geolsoc.org.uk\\\\\\\/SUP18535.\\""

The “Brecciated Limestones” of Maiella, Italy: Rheological implications of hydrocarbon-charged fluid migration in the Messinian Mediterranean Basin

“…The p-ev1 deposits consist of resedimented lower evaporites, barren shales, and brecciated and concretionary carbonates ("Brecciated Limestones"). Upper postevaporitic deposits (p-ev2) unconformably overlie the p-ev1 deposits through a younger erosional surface (MES2, Cosentino et al, 2010b;Cipollari et al, 2013;, and document the oligohaline late Messinian Lago-Mare event (Cipollari et al, 1999;Crescenti et al, 2002;Gliozzi et al, 2002Gliozzi et al, , 2012Cosentino et al, 2005, correlatable to the Loxocorniculina djaffarovi zone (Carbonnel, 1978;Grossi et al, 2011).…”

The Miocene–Pliocene boundary and the Messinian Salinity Crisis in the easternmost Mediterranean: Insights from the Hatay Graben (Southern Turkey)

“…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).…”

“…Interestingly, Consentino et al (2010) also recognise two Messinian erosion surfaces in the Adana Basin; one correlating to the wider MES cutting the lower evaporites, and the other at the base of the overlying continental sequence. Burton-Ferguson et al (2005) thought that these continental sediments were Pliocene in age; however, Ilgar et al (2012) have identified Gilbert-type deltas that are laterally equivalent to the gypsum deposits, and microfossil analysis by Cipollari et al (2013) and Faranda et al (2013) showed that these sediments were deposited in brackish water environments of the latest Messinian Lago Mare event. Cipollari et al (2013) also showed that subsequent Zanclean reflooding resulted in the deposition of deep marine marls in water depths of 200 -500 m.…”

Deep-seated hydrocarbons in the seep “Brecciated Limestones” of the Maiella area (Adriatic foreland basin): Evaporitic sealing and oil re-mobilization effects linked to the drawdown of the Messinian Salinity Crisis

“…2). Finally, p-ev2 deposits unconformably overlie p-ev1 deposits through a younger erosional surface (MES2, Cosentino et al, 2010;Cipollari et al, 2013) and are overlain by Early Pliocene bathyal clays (Cipollari et al, 2003). P-ev2 deposits in the Maiella area contain rich Lago-Mare fauna with Paratethyan immigrants (Patacca et al, 1992;Cipollari et al, 1999;Gliozzi et al, 2002;Crescenti et al, 2002;Cosentino et al, 2005Gliozzi et al, 2012).…”
