Plain Language Summary The southern slope of the Greater Caucasus mountains is the site of a former rift basin. In order to explain shortening deficits, plate deceleration, and the ~5 Ma reorganization of the Arabia‐Eurasia collision zone Cowgill et al. (2016) proposed that this basin closed ~5 Myrs ago. Within the western Greater Caucasus, at least, careful examination of sedimentological, provenance, and seismic data, however, supports an earlier ~35 Ma basin closure age. Basin closure cannot therefore be the driving mechanism for the ~5 Ma deceleration of the Arabian plate and reorganization of the Arabia‐Eurasia collision zone.

“…Where coarse siliciclastic components are not present in the early Oligocene part of the series, a basal hiatus and olistostrome deposition and/or an increase in the degree of micropaleontological reworking also constrain initial uplift and sediment derivation from the wGC to the earliest Oligocene (e.g., Figure , log E). Spectacular Maykop Series turbidite fans derived from the wGC have been imaged on 3‐D seismic data within the Tuapse Trough [ Mityukov et al ., ]. The volume of derived sediment, the large percentage of terrestrial in situ palynomorphs, and evidence for varying degrees of surface weathering revealed in heavy mineral data [ Vincent et al ., ; Vincent et al ., ] all indicate that this sediment source was primarily subaerial.…”

The western Greater Caucasus formed by the tectonic inversion of the western strand of the Greater Caucasus Basin, a Mesozoic rift that opened at the southern margin of Laurasia. Subsidence analysis indicates that the main phase of rifting occurred during the Aalenian to Bajocian synchronous with that in the eastern Alborz and, possibly, the South Caspian Basin. Secondary episodes of subsidence during the late Tithonian to Berriasian and Hauterivian to early Aptian are tentatively linked to initial rifting within the western, and possibly eastern, Black Sea and during the late Campanian to Danian to the opening of the eastern Black Sea. Initial uplift, subaerial exposure, and sediment derivation from the western Greater Caucasus occurred at the Eocene‐Oligocene transition. Oligocene and younger sediments on the southern margin of the former basin were derived from the inverting basin and uplifted parts of its northern margin, indicating that the western Greater Caucasus Basin had closed by this time. A predominance of pollen representing a montane forest environment (dominated by Pinacean pollen) within these sediments suggests that the uplifting Caucasian hinterland had a paleoaltitude of around 2 km from early Oligocene time. The closure of the western Greater Caucasus Basin and significant uplift of the range at approximately 34 Ma is earlier than stated in many studies and needs to be incorporated into geodynamic models for the Arabia‐Eurasia region.

“…A young age for uplift would limit the amount of clastic (potential reservoir) sediment entering the basin from its margins during the deposition of the Maykop Suite, for example. Seismic data (Afanasenkov et al 2007;Nikishin et al 2010;Mityukov et al 2011) demonstrate thickening of the Maykop Suite into the Tuapse and Indolo-Kuban foreland basins to the south and north of the Greater Caucasus, respectively, supporting the notion of Vincent et al (2016) that the Caucasus were forming during the Oligocene.…”

Spectacular Maykop Suite turbidite fans derived from the Greater Caucasus have been imaged on 3D seismic data from within the Tuapse Trough (Mityukov et al 2011). Vincent et al (2013a, b) and Khlebnikova et al (2014) have demonstrated that Maykop sandstones in the Russian western Caucasus are significantly more quartz-rich than those located farther SE in western Georgia.…”

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...
