History of oceanic front development in the New Zealand sector of the Southern Ocean during the Cenozoic--a synthesis [PDF]

, 2001
The New Zealand sector of the Southern Ocean (NZSSO) has opened about the Indian-Pacific spreading ridge throughout the Cenozoic. Today the NZSSO is characterised by broad zonal belts of antarctic (cold), subantarctic (cool), and subtropical (warm ...

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

Journal of Quaternary Science, Volume 41, Issue 4, Page 602-621, May 2026.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Scale and structure of time-averaging (age mixing) in terrestrial gastropod assemblages from Quaternary eolian deposits of the eastern Canary Islands [PDF]

, 2007
Quantitative estimates of time-averaging (age mixing) in gastropod shell accumulations from Quaternary (the late Pleistocene and Holocene) eolian deposits of Canary Islands were obtained by direct dating of individual gastropods obtained from ...

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

TERTIARY PALAEOGEOGRAPHY OF JAPAN

Journal of Geography (Chigaku Zasshi), 1938
In this treatise, six Palaeogeographic maps of Tertiary Japan are given, representing the different stages of the Tertiary Epoch. To facilitate comparison, those of the three stages of Cretaceous have been added. On each map is shown the distribution of Land and Sea when the sea transgression was the greatest.

Evidence for coal forest refugia in the seasonally dry Pennsylvanian tropical lowlands of the Illinois Basin, USA [PDF]

, 2014
The Moscovian plant macroflora at Cottage Grove southeastern Illinois, USA, is a key example of Pennsylvanian (323–299 Million years ago) dryland vegetation.

Assessing the Response of Blanket Peatlands to Climate Change Using the DigiBog Model and Winter's Concept of the “Hydrologic Landscape”

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Peatlands are important global carbon stores, but it is unclear whether they will continue as carbon sinks under future climates, or degrade, leaking carbon to the atmosphere. We used the DigiBog peatland development model to explore this question for a blanket peatland in Glen Affric, Scotland, investigating how topography and climate have ...

A database of detrital zircon U–Pb ages and Hf isotopes for the Middle East (Iranian and Arabian plates)

Geoscience Data Journal
The detrital zircon records significant information in the ‘source‐sink’ system. With the application of in situ laser ablation technology, a large number of high‐quality detrital zircon data have been published since 2000.

The Jurassic of Denmark and Greenland: Sequence stratigraphy of the Jurassic of the Danish Central Graben [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2003
A sequence stratigraphic framework is established for the Jurassic of the Danish Central Graben based primarily on petrophysical log data, core sedimentology and biostratigraphic data from about 50 wells.
