Insights into the Early Evolution of the Côte d’Ivoire Margin (West Africa) [PDF]
, 2018 A tectono-stratigraphic analysis of a broadband 3D seismic survey over the outer slope of Côte d’Ivoire margin, west Africa, revealed that Cenomanian and younger strata seal well-developed rift fault blocks up to 15 km across. Growth strata indicate that

Albian ammonite biostratigraphy in Northwest Bulgaria
Geologica Balcanica, 1991 The Albian Stage in Northwest Bulgaria is of more restricted occurrence compared to the other Lower Cretaceous Stages. It consists of marls interbedded by clayey limestones and by less common sandstones (Sumer Formation) and glauconitic sandstones, siltstones and marls (Malo Peštene Formation). The Albian sediments are of considerable thickness without

Glomospirella cantabrica n. sp., and other benthic foraminifera from Lower Cretaceous Urgonian-type carbonates of Cantabria, Spain : biostratigraphic implications [PDF]
, 2016 A new benthic foraminifer is described as Glomospirella cantabrica n. sp. from several sections of the Upper Aptian Reocín Formation and one occurrence in the lowermost Albian Las Peñosas Formation of Cantabria (northern Spain).

Rising and falling diapirs, shifting depocenters, and flap overturning in the Cretaceous Sopeira and Sant Gervàs subbasins (Ribagorça Basin, southern Pyrenees) [PDF]
, 2016 The halokinetic structure of inverted salt-related continental margins is frequently obliterated by compressional overprinting. The Cretaceous Sopeira and Sant Gervàs subbasins of the Ribagorça Basin (south central Pyrenees) show evidence of salt-related

The biostratigraphy of the Albian and Cenomanian succession in the Ventnor No. 2 borehole, Isle of Wight [PDF]
, 2004 This report describes the foraminifera found in the uppermost part of the Gault, Upper Greensand, Glauconitic Marl and West Melbury Marly Chalk of Ventnor No.2 Borehole (the "Carstone of the Isle of Wight" was barren of calcareous microfaunas).

Microfacies of a Lower Cretaceous marine successions in Cerro Las Conchas, Sonora, Mexico
Revista Mexicana de Ciencias Geológicas, 2019 The upper Aptian-middle Albian marine sequence exposed in the Cerro Las Conchas is clearly upside down, being the middle Albian rocks in the topographic base of the sequence, while the upper Aptian is in the upper part of the section.

CRETACEOUS HIGH-LATITUDE TERRESTRIAL ECOSYSTEMS: AN EXAMPLE FROM ALEXANDER ISLAND, ANTARCTICA
Publicación Electrónica de la Asociación Paleontológica Argentina, 2015 A thin wedge of non-marine sedimentary strata occurs within the largely marine Fossil Bluff Group on Alexander Island, Antarctica. The late Albian Triton Point Member of the Neptune Glacier Formation records deposition by braided and meandering river ...
