“…Uplift and erosion occurred in the Valanginian and Hauterivian, and was followed in the Barremian-Aptian by synrift deposition of a more than 2 km-thick succession of turbidites (the Çagl-ayan Formation) in basinal depocentres (Okay et al 2013); whereas on the present-day Black Sea coast, shallow-marine and continental deposition occurred (Yılmaz & Altiner 2007;Masse et al 2009) (Fig. 3).…”

Abstract:The exploration for petroleum in the Black Sea is still in its infancy. Notwithstanding the technical challenges in drilling in its deep-water regions, several geological risks require better understanding. These challenges include reservoir presence and quality (partly related to sediment provenance), and the timing and migration of hydrocarbons from source rocks relative to trap formation. In turn, these risks can only be better understood by an appreciation of the geological history of the Black Sea basins and the surrounding orogens. This history is not without ongoing controversy. The timing of basin formation, uplift of the margins and facies distribution remain issues for robust debate. This Special Publication presents the results of 15 studies that relate to the tectonostratigraphy and petroleum geology of the Black Sea. The methodologies of these studies encompass crustal structure, geodynamic evolution, stratigraphy and its regional correlation, petroleum systems, source to sink, hydrocarbon habitat and play concepts, and reviews of past exploration. They provide insight into the many ongoing controversies regarding the geological history of the Black Sea region and provide a better understanding of the geological risks that must be considered for future hydrocarbon exploration. The Black Sea remains one of the largest underexplored rift basins in the world. Although significant biogenic gas discoveries have been made within the last decade, thermogenic petroleum systems must be proven through the systematic exploration of a wide variety of play concepts.Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.The Black Sea, located between Russia, Georgia, Turkey, Bulgaria, Romania and Ukraine, covers an area of approximately 423 000 km 2 with a maximum water depth of 2245 m. Sedimentary thickness can exceed 14 km. The Black Sea holds an abiding fascination for petroleum geologists and is a true frontier basin with very few wells drilled in its deepwater sector. Abundant seepage, outcrops of potential source rocks around its margins, large potential traps imaged on seismic data, and a variety of potential reservoir and play concepts point towards considerable potential to reward the successful explorer. This volume brings together several geoscience studies (Fig. 1) that provide additional information about the origins of the Western and Eastern Black Sea basins, their tectonostratigraphic history, sedimentary fill and petroleum potential.The Black Sea and its surrounding regions have a long history of geological research: for example, it has long been regarded as the type example of an euxinic basin in which bottom water anoxia and free hydrogen sulphide (H 2 S) result in an absence of benthonic life and the preservation of organic matter (Wignall 1994). Somewhat ironically, the term 'euxinic' is derived from an ancient Greek name for the sea, Pontus Euxinus, meaning the welcoming or hospitable sea. Another ancient Greek name (probably derived from an Iranian nam...

“…This is confirmed by a synchronous major negative excursion of marine 187 Os/ 188 Os Bottini et al, 2012) indicative of increased supply of non-radiogenic Os by weathering from continents. Recent sedimentological and microfacies studies of OAE-1a equivalents in shallowwater settings (Immenhauser et al, 2005;Embry et al, 2010;Huck et al, 2010;Najarro et al, 2011), show that carbonate production around that interval can be permanently or temporarily replaced by terrigenous sediments with episodic development of abundant orbitolinid faunas Luciani et al, 2004;Föllmi and Gainon, 2008;Masse et al, 2009). In other cases these environments develop microbial carbonates such as those reported in Oman (Pittet et al, 2002;Immenhauser et al, 2005;Rameil et al, 2010), and in the Adriatic region (Huck et al, 2010).…”

Early Cretaceous sedimentation and orogeny on the active margin of Eurasia: Southern Central Pontides, Turkey

The Pontides in northern Turkey constituted part of the southern active margin of Eurasia during the Mesozoic. In the Early Cretaceous, a large submarine turbidite fan covered most of the Central Pontides. New U‐Pb detrital zircon data imply that the major source of the turbidites was the East European Craton‐Scythian Platform in the north. This implies that there was no thoroughgoing Black Sea basin between the Pontides and the East European Craton during the Early Cretaceous. The Lower Cretaceous turbidites are bounded in the south by a large metamorphic area, the Central Pontide Supercomplex (CPS). New geological mapping, petrology, and U‐Pb zircon and Ar‐Ar muscovite ages indicate that the northern part of the CPS consists of Lower Cretaceous distal turbidites deformed and metamorphosed in a subduction zone in the Albian. The rest of the CPS is made of Middle Jurassic, Lower Cretaceous, and middle Cretaceous (Albian) metamorphic belts, each constituting distinct subduction‐accretion units. They represent episodes of collision of oceanic volcanic arcs and oceanic plateaus with the Eurasian margin and are marked in the stratigraphy of the hinterland by periods of uplift and erosion. The accretionary complexes are overlain by Upper Cretaceous (Turonian‐Santonian) volcano‐sedimentary sequences deposited in a fore‐arc setting. The detrital zircon data, middle Cretaceous (Albian) metamorphism, and widespread Albian uplift of the Black Sea region suggest that Early Cretaceous (Barremian‐Aptian) nonvolcanic rifting and Late Cretaceous (Turonian‐Santonian) opening of the Black Sea by the splitting of the arc are unrelated events.
