“…This low trench retreat (figure 12b) contrasts with the large crustal stretching and subsequent oceanic spreading occurring at the same time in the Black Sea basin (figures 8a-h and 10) [Zonenshain and Le Pichon, 1986;Görür, 1988;Hippolyte et al, 2010;Nikishin et al, 2015b].…”

“…Intense crustal stretching ultimately led to oceanic spreading from Cenomanian to Santonian times (i.e. ~100 to 85 Ma) [Nikishin et al, 2015b]. The Black Sea basin then underwent compressional deformation in the late Eocene (figure 5), identifiable in the observed reworking of pre-existing structures [Zonenshain and Le Pichon, 1986;Nikishin et al, 2015b].…”

“…At the same time, the magmatic activity seems to migrate southward [Yılmaz et al, 1997;Ciobanu et al, 2002;von Quadt et al, 2005;Eyüboğlu et al, 2010] suggesting a southward retreat of the oceanic slab Kolb et al, 2012]. Further north, the opening of the Black Sea basin was associated with an intense stretching of the crust and oceanic spreading in Cenomanian to Santonian times [Zonenshain and Le Pichon, 1986;Görür, 1988;Hippolyte et al, 2010;Nikishin et al, 2015b]. An additional shoshonitic and alkaline volcanism was simultaneously emplaced in the eastern Srednogorie region, just west of this extensional domain (figures 8g-h) [Boccaletti et al, 1978].…”

“…Recent, seismic studies in this part of the Black Sea even show a complex infill related to channel deposits and erosional surfaces from the present back to the Eocene (Nikishin et al, 2015b). These erosional surfaces are potentially related to a paleo-Bosporus strait, causing subaqueous erosion and sediment transport into the basin (Nikishin et al, 2015a). Furthermore, a large number of mass transport complexes is located along the Black Sea margin (Tari et al, 2015).…”

A Greigite-Based Magnetostratigraphic Time Frame for the Late Miocene to Recent DSDP Leg 42B Cores from the Black Sea

Throughout the Late Neogene, the Black Sea experienced large paleoenvironmental changes, switching between (anoxic) marine conditions when connected to the Mediterranean Sea and (oxic) freshwater conditions at times of isolation. We create a magnetostratigraphic time frame for three sites drilled during Deep Sea Drilling Project (DSDP) Leg 42B to the Black Sea (drilled in 1975). At the time, magnetostratigraphic dating was impossible because of the presence of the little understood iron sulfide mineral greigite (in sediments a precursor to pyrite) as magnetic carrier. Our rock-magnetic results indicate that only anoxic conditions result in poor magnetic signal, likely as a result of pyrite formation in the water column rather than in the sediment. The magnetostratigraphic results indicate that Hole 379A, drilled in the basin center, has a continuous sedimentary record dating back to 1.3 Ma. Hole 380/380A is subdivided into three consistent intervals, 0-700 mbsf, 700-860 mbsf, and 860-1075 mbsf. The top unit covers the Pleistocene but the magnetostratigraphy is likely compromised by the presence of mass transport deposits. The middle unit spans between 4.3 and 6.1 Ma and records continuous deposition at ∼10 cm/kyr. The lower unit lacks the independent age constraints to correlate the obtained magnetostratigraphy. Hole 381 is drilled on the Bosporus slope and as a result, hiatuses are common. A correlation to the nearby Hole 380/380A is proposed, but indicates deposits cannot straightforwardly be traced across the slope. Our improved age model does not support the original interpretation based on these cores of a desiccation of the Black Sea during the Messinian salinity crisis.

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.
