Journal: :Cretaceous Research 2022

Here we describe a new Lower Cretaceous palynoflora from the Lusitanian Basin, located in westernmost sector of Iberian Peninsula. The spore-pollen assemblage was extracted samples collected Carregueira clay pit complex, near village Juncal, western Portugal, sedimentary deposits belonging to Figueira da Foz Formation. A rich and well-preserved palynoflora, typical non-marine fluvial environmen...

The Cretaceous outcrops of Borj Cedria-Bou Kournine area belongs to the NE-trending Atlas system northern Tunisia. This exposes sub-meridian folds associated with numerous N- NW-trending major fault systems. study together previous surveys reveals that this N-trending folding is believed be related inversion Jurassic and Early pre-existing zones generated in response late compressive deformatio...

Abstract The structure and tectonic evolution of the Cretaceous rift basins southern Egypt are poorly understood. In this study, tectonostratigraphy Komombo Basin has been determined using seismic, well biostratigraphic data. basin is compared to Kharit, Nuqra Beni Suef in as Muglad Sudan. a 58 km long, 28 wide NW–SE trending half‐graben infilled with 2200 m Berriasian‐Maastrichtian sediments o...

Journal: :Geosphere 2022

Abstract We evaluate the Cretaceous stratigraphy and carbon sequestration potential of northern Baltimore Canyon Trough (NBCT) using >10,000 km multi-channel seismic profiles integrated with geophysical logs, biostratigraphy, lithology from 29 offshore wells. identify map six sequences resolved primarily at stage level. Accommodation was dominated by thermal non-thermal subsidence, thoug...

Aitamir Formation (Albian-Cenomanian) is one of the stratigraphic units in the Kopet Dagh basin that consists of glauconitic sandstone, siltstone, shale and limestone. Glaucony is present in all lithofacies of this formation and varies based on degree of maturity and color ranging from pale to very dark green. Percentage of glaucony in sandstones and shell beds ranges from 1 to 40, poorly to mo...
