Palynostratigraphic and palynofacies analysis have been performed on hydrocarbon seep carbonate, carbonate nodule mudstone samples from the Early Cretaceous Kuhnpasset Beds in area of Wollaston Forland, Northeast Greenland. Three informal palynostratigraphic zones defined based dinoflagellate cyst occurrences. The range ?early Barremian to early Aptian age, correlate with previously These indic...

Benthic foraminifera at Ocean Drilling Program (ODP) Hole 692B were studied to understand variations in oxygen and organic-matter fluxes bottom waters during the Early Cretaceous. The upper Berriasian lower Barremian black shales, characterized by high concentrations of total organic carbon (TOC) ranging between 1.3 18%, deposited an outer neritic-upper bathyal environment (~200–500 m) accordin...

Most of the Caribbean plate, which currently lies between American continents, represents a mantle plume-derived 8–20 km thick Cretaceous oceanic plateau that was formed in Pacific region and moved eastwards. The northern islands are largely made up dismembered island arc located along western entrance to inter-American (termed Great Arc Caribbean) mid-late Cretaceous. Importantly, timing litho...

Fossil-wood carbon-isotope data are presented for the Wessex Formation, a non-marine unit within the Lower Cretaceous (Valanginian–Barremian) Wealden Group of the Isle of Wight and Dorset, southern England. The carbon-isotope values have a range ( C c. 26.6 to 19.8‰) that is consistent with that expected for Mesozoic C3 plants. Consideration of the Isle of Wight fossil-wood carbon-isotope data ...

at the boundary between jurassic and cretaceous, because of late kimmerian movements, the sea ragressed from many areas of north and cantral iran, and many continental areas rose, which included a number of differentiated basins. the boundary between jurassic and cretaceous in these parts of iran is usually marked by a big diastem or by red, clastic and evaporitic sediments. the whole or part o...

Palynostratigraphy and palynofacies analyses are applied to identify transgressive-regressive sequences changes in paleoenvironment through the Middle Jurassic–Early Cretaceous succession of Ramså Basin on Andøya. The conglomerate, succeeding lacustrine-swamp deposits Hestberget Kullgrøfta members (Ramså Formation) overlying terrestrial marginal marine lower Bonteigen Member Formation), compris...

Since 1950, diverse assemblages of Mesozoic vertebrates have been described from the Galve area (Teruel Province, NE Spain). More than fifty taxa have been noted, including fishes, crocodyliforms, pterosaurs, dinosaurs and mammals. The Galve fossil sites occur in an Upper Jurassic to Lower Cretaceous succession spanning some 30 myr, divided into five formations, representing marginal marine and...

The Lower Cretaceous Tuxen (lower Hauterivian – upper Barremian) and Sola (upper Barremian Albian) Formations in the Danish Central Graben (North Sea) constitute one of oldest chalk successions recorded globally, but have received little attention with regards to sedimentary facies depositional processes. This study presents first comprehensive carbonate analysis succession, retrieved from seve...
