Cool early Albian climates; new data from Argentina [PDF]
Cretaceous Research, 2004 Previous studies on the stable isotope geochemistry of dimitobelid belemnites from Antarctica and Australia indicated cool climatic conditions during the early Albian in the shelf seas around the Gondwanan margin.

The Albian tectonic “crisis” in Central Tunisia: Nature and chronology of the deformations
Journal of African Earth Sciences, 2013 The Mid-Cretaceous tectonic "crisis" is a classical feature of the tectono-sedimentary evolution of Tunisia. A reappraisal of synsedimentary deformation observed in the Tajerouine and Kasserine areas shows that deformation began in the earliest Albian ...

ON THE PHYLOGENY OF THE LATE ALBIAN GENUS PLANOMALINA
The Journal of Foraminiferal Research, 2006The ancestor-descendant relationships of the late Albian Planomalina lineage have been reconstructed using morphologic observations obtained from the Scanning Electron Microscope and supported by morphometric analysis using X-ray images of the shell ontogeny.

Albian pelagic rhythms (Piobbico core)
SEPM Journal of Sedimentary Research, 1991ABSTRACT The Piobbico core of Aptian-Albian pelagic rhythmites in Italy has been used to explore ways of extracting quantitative time-series of geological, chemical, physical and biological parameters from stratigraphic sequences. Recognition of the precession, obliquity, and eccentricity cycles (the Option frequencies) has permitted time-resolution to

Paleoceanography of the northwestern Pacific during the Albian
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007Abstract The deep ocean conditions and circulation during the Cretaceous have been characterized mainly by the sediments from the Tethys Sea and the proto-Atlantic Ocean, because sedimentological data from the Pacific basin from that period have been quite limited. Here we present new geochemical measurements from sediments that we collected from two

Note on the Lower Albian at Leighton Buzzard
Geological Magazine, 1942Recent examination of the well-known Shenley Hill Limestone lenticles and of the Regularis Nodules of Billington Crossing has resulted in the discovery of a number of new records. It will be remembered that Lamplugh and Walker in 1903 (1) and Lamplugh again in 1922 (2) placed the Shenley Hill Limestone at the top of the Lower Greensand both on ...

Albian Foraminifera of the Rumanian Plain
Micropaleontology, 1965Describes foraminifera (including one new species and new subspecies) from marly Albian (Cretaceous) deposits of the Giurgiu and Putineiu regions. Tabulated data on biozonal distribution of the fauna are included.

Radiolarian paleobiogeography in the late Albian–Santonian
Stratigraphy and Geological Correlation, 2016Radiolarian paleobiogeography for the late Albian–Santonian is proposed for the first time. The paleobiogeographic differentiation is found to be different for the Albian, Cenomanian, Turonian, and Coniacian–Santonian. The Tethyan and Boreal superrealms can be recognized for the Albian–Santonian.

Albian Foraminifera of the Yukon Territory
1978The results of this study provide a foraminiferal reference sequence for the Albian Stage in the Yukon Territory, a previously little-known region between the Alaskan North Slope and the Canadian Western Interior. Eighteen families, forty-three genera, and one hundred and thirty-five species of the order Foraminifera are reported from the Albian ...
