The Hell Creek Formation, Montana: A Stratigraphic Review and Revision Based on a Sequence Stratigraphic Approach

Geosciences, 2020
The Upper Maastrichtian fluvial Hell Creek Formation of the Fort Peck Lake area, Montana (and regional equivalents) is notable for its vertebrate fossils and for the K-Pg mass extinction at or near its upper contact.

The early/middle Eocene transition at the Ésera valley (South Central Pyrenees): Implications in Shallow Benthic Zones (SBZ)

Geologica Acta, 2022
An integrated study including magnetostratigraphy, larger benthic foraminifera and calcareous nannofossil biostratigraphy is presented herein. This work was performed in shallow marine siliciclastics rich in larger foraminifera, around the Ypresian ...

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

Journal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

The tectono-stratigraphic evolution of the Fucino Basin (central Apennines, Italy): new insights from the geological mapping of its north-eastern margin.

Journal of Maps, 2021
We present the geological map of the north-eastern margin of the Fucino Basin, which is mainly characterized by Plio-Quaternary continental deposits that show transition from deeper-water lacustrine environment, marginal lacustrine system, and fluvial ...

Impact of Upward Oxygen Diffusion From the Oceanic Crust on the Magnetostratigraphy and Iron Biomineralization of East Pacific Ridge-Flank Sediments

Frontiers in Earth Science, 2021
Recent measurements of pore-water oxygen profiles in ridge flank sediments of the East Pacific Rise revealed an upward-directed diffusive oxygen flux from the hydrothermally active crust into the overlying sediment.

Palaeomagnetic and synchrotron analysis of >1.95 Ma fossil-bearing palaeokarst at Haasgat, South Africa

South African Journal of Science, 2014
Palaeomagnetic analysis indicates that Haasgat, a fossil-bearing palaeocave in the Gauteng Province of South Africa, is dominated by reversed magnetic polarity in its oldest, deepest layers and normal polarity in the younger layers.

New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.

Correlation of peat sections of the Lower Priamurye based on the results of calculation of relative paleointensity

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
The paper considers the possibility of determining the age and correlating peat sections by solving the inverse problem of magnetostratigraphy based on the findings of comprehensive (palaeomagnetic, petromagnetic, microprobe, and radiocarbon) studies on ...
