Correlation of Albian European and Tethyan ammonite zonations and the boundaries of the Albian Stage and substages: some comments

open access: yes, 1999
Although the so-called ‘standard’ ammonite zonation of the Albian contains index species which occur in the Tethyan province, the scheme largely reflects the faunal succession in the European faunal province with its endemic sonneratiinid and hoplitinid faunal elements.

Assessment of prospects for petroleum bearing Aptian-Albian-Cenomanian strata of the Yamal peninsula - north of Western Siberia, on the basis of 2D seismic survey [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2022
The article presents a brief description of the geological structure and petroleum potential of the Aptian-Albian-Cenomanian strata. On the basis of 2D seismic exploration as part of the Aptian and Albian-Cenomanian levels, new promising objects were ...

Albian and Cenomanian selachian assemblages from North East England. [PDF]

open access: yes, 1999
Bulk sampling of the marls and marly limestones of the Hunstanton Formation (Red Chalk) and associated deposits at two sites in north-east England has yielded rich and diverse assemblages of small selachians, largely represented by dissociated teeth ...

Does aid fuel corruption? New evidence from a cross-country analysis

open access: yesDevelopment Studies Research, 2021
This study estimates the effect of foreign aid on corruption using a Two-Step Least Squares method. We address endogeneity using instrumental variables that capture geographical and cultural proximities between donor and recipient countries.

First discovery of nautilids from the Albian–Cenomanian succession of the Koppeh Dagh Basin, NE Iran

open access: yesSwiss Journal of Palaeontology, 2021
The Aitamir Formation, situated in the Koppeh Dagh Basin in the northeast of Iran, is known for its well-exposed Albian-to-Cenomanian succession. Although geologists previously documented a number of macro- and microfossils, no nautilids had been ...

Aptian–Albian deposits of the Ait Ourir basin (High Atlas, Morocco): New additional data on their paleoenvironment, sedimentology, and palaeogeography

open access: yesOpen Geosciences, 2020
This sedimentological and palaeontological analysis of the Aptian–Albian sedimentary succession of the Ait Ourir basin in the High Atlas Mountains of Marrakesh in Morocco provides new data from a previously poorly understood basin.

Mid-Cretaceous paleoenvironmental changes in the western Tethys [PDF]

open access: yesClimate of the Past, 2018
We present a continuous record of surface water temperature and fertility variations through the latest Barremian–Cenomanian interval (ca. 27 Myr) based on calcareous nannofossil abundances from the western Tethys.

Sedimentary record of the “Austrian” tectonic pulse around the Aptian–Albian boundary in SE France, and abroad

open access: yesComptes Rendus. Géoscience, 2022
A tectonically-controlled forced regression occurred on the western margin of the French subalpine basin around the Aptian–Albian boundary. It nearly emptied the western part of the Vocontian Trough during the early and middle Albian.
