Geo log i cal Quar terly, 58 (4): 707-728, doi: 10.7306/gq.1167The So³okija Graben is a tec tonic struc ture in Roztocze, in south east ern Po land, unique by its infill of Eocene ma rine strata. The more than 40 m thick sandy suc ces sion is the only well-dated palaeontological ev i dence of the Eocene ma rine transgres sion of an epicontinental sea in this part of Po land: the sur round ing area is de void of co eval ma rine strata, which were since eroded away. The So³okija Graben suc ces sion is hence cru cial for the palaeogeographic re con struc tion of south eastern Po land dur ing the Eocene as well as for the tec tonic his tory of this re gion. To ob tain pre cise age de ter mi na tion, the 33 m thick suc ces sion of loamy sands that fill the So³okija Graben at Leliszka and the 4 m thick suc ces sion at £aszczówka were sam pled via bore hole cores for dinoflagellate cysts. Sam ples from £aszczówka are bar ren, whereas those from Leliszka con tain rich and tax o nom i cally di verse as sem blages. Their biostratigraphical in ter pre ta tion sup ports pre vi ous re sults suggest ing a Bartonian age for most of the So³okija Graben suc ces sion; the pos tu lated Priabonian age of its non-cal car e ous part was doc u mented in its up per most part only. The palynological re cord also al lows re con struc tion of the sed i men tary set ting of the Leliszka suc ces sion. The basal part of the Bartonian was de pos ited in a shal low but ex ten sive ma rine ba sin char ac terized by nor mal sa lin ity and rel a tively high-en ergy hy dro dy namic con di tions. Sub se quently, ma rine ba sin un der went grad ual shallowing with a tem po rary halt in sed i men ta tion. Dur ing the Late Bartonian the ba sin be came brack ish. A short-du ra tion Early Priabonian ma rine ba sin was char ac ter ized by shal low-ma rine con di tions; it be came brack ish dur ing its fi nal stage. Com par i son with neigh bour ing Eocene de pos its of the epicontinental and Carpathian bas ins shows that the ma rine ba sin at Roztocze was pre sum ably con nected with both dur ing the Bartonian, and sep a rated from the Carpathian ba sin dur ing the Early Priabonian. Fac tors con trol ling the sea way pat tern of the Roztocze Ba sin in cluded eustasy and tec tonic move ments, the for mer dom i nat ing dur ing the Bartonian, and co-oc cur ring with up lift of the Meta-Carpathian Swell dur ing the Early Priabonian.

Latest Cretaceous climatic and environmental change in the South Atlantic region

et al. 2017

View full text Add to dashboard Cite

Latest Maastrichtian climate change caused by Deccan volcanism has been invoked as a cause of mass extinction at the Cretaceous‐Paleogene (K‐Pg) boundary (~66.0 Ma). Yet late Maastrichtian climate and ecological changes are poorly documented, in particular on the Southern Hemisphere. Here we present upper Maastrichtian‐lower Danian climate and biotic records from the Bajada del Jagüel (BJ) shelf site (Neuquén Basin, Argentina), employing the TEX86 paleothermometer, marine palynology (dinoflagellate cysts), and micropaleontology (foraminifera). These records are correlated to the astronomically tuned Ocean Drilling Program Site 1262 (Walvis Ridge). Collectively, we use these records to assess climatic and ecological effects of Deccan volcanism in the Southern Atlantic region. Both the TEX86‐based sea surface temperature (SST) record at BJ and the bulk carbonate δ18O‐based SST record of Site 1262 show a latest Maastrichtian warming of ~2.5–4°C, at 450 to 150 kyr before the K‐Pg boundary, coinciding with the a large Deccan outpouring phase. Benthic foraminiferal and dinocyst assemblage changes indicate that this warming resulted in enhanced runoff and stratification of the water column, likely resulting from more humid climate conditions in the Neuquén Basin. These climate conditions could have been caused by an expanding and strengthening thermal low over the South American continent. Biotic changes in response to late Maastrichtian environmental changes are rather limited, when compared to the major turnovers observed at many K‐Pg boundary sites worldwide. This suggests that environmental perturbations during the latest Maastrichtian warming event were less severe than those following the K‐Pg boundary impact.

Dinoflagellate cyst stratigraphy and palaeoenvironment of the marginal marine Middle and Upper Miocene of the eastern Campine area, northern Belgium (southern North Sea Basin)

A stratigraphical and palaeoenvironmental analysis with organic‐walled palynomorphs of the Bolderberg and Diest formations provides new insights in the depositional history during Miocene times at the southern border of the North Sea Basin. The Neogene transgression invaded Belgium from a north–northwestern direction and fully marine sediments were deposited in the northern part of Belgium. The age and the palaeoenvironment of the deposits at the very border of the southern North Sea Basin remained till a few decades ago incomplete. The recovered dinoflagellate cysts, acritarchs and green algae from the Bolderberg Formation in the Wijshagen Borehole indicate a marginal marine depositional environment during late Burdigalian and Langhian times in the eastern Campine area, in contrast to the deeper marine conditions prevailing to the north–northwest. The relative dating of the Bolderberg Formation confirms that maximum flooding occurred during Langhian to early Serravallian times. Deposition apparently took place during the Middle Miocene Climatic Optimum, and ended when the climatic deterioration set in at around 14 Ma. A hiatus spanning ca. 2 Ma separates the Middle Miocene Bolderberg Formation from the Upper Miocene Diest Formation in the eastern Campine area at the border of the North Sea Basin.
