Paleosols in Hokkaido

The Quaternary Research (Daiyonki-Kenkyu), 1964
Hokkaido is divided to three soil regions, that is, the northern, cetnral and southern regions as shown in Fig. 1. But the brown forest soils with leached top horizon are widely distributed in the southern soil region where the occurrence of the podzolic soils could not be expected under the recent bio-climatic conditions.

Identification and correlation of the Aso‐3 tephra in the Omaezaki area, central Japan: A valuable key stratum for the MIS 6/5 transition period

Journal of Quaternary Science, Volume 41, Issue 6, Page 972-986, August 2026.
ABSTRACT The Aso‐3 tephra is one of the most significant widespread marker layers from the Middle to Late Pleistocene, generated by a large caldera‐forming eruption at the Aso volcano in Kyushu, southwestern Japan. Despite its importance, a distal co‐ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass ...

Reappraisal of Holocene Caldera Resurgence at Campi Flegrei (Southern Italy): A Long‐Lived Magma‐Driven Resurgent Dome System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Intensification of Northern Hemisphere Glaciation Triggered the Red Clay to Loess‐Paleosol Shift on the Chinese Loess Plateau 2.7 Million Years Ago

Geophysical Research Letters
Widespread aeolian loess‐paleosol and red clay sediments on the Chinese Loess Plateau (CLP) provide a globally unique terrestrial archive of Neogene–Quaternary climate.

Dansgaard‐Oeschger Events Recorded in Low‐Latitude Marine Sediments and Teleconnection With High‐Latitude Climate Variations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Dansgaard‐Oeschger (D‐O) events are millennial‐scale high‐latitude climate oscillations with abrupt climate transitions between stadial and interstadial conditions, which are well recorded in and outside of high northern latitudes. However, their signal propagation mechanisms from high to low latitudes are uncertain.

Revisiting Late Pleistocene Loess–Paleosol Sequences in the Azov Sea Region of Russia: Chronostratigraphy and Paleoenvironmental Record

Frontiers in Earth Science, 2022
Loess-paleosol sequences are the most intensively studied terrestrial archives used for the reconstruction of Late Pleistocene environmental and climatic changes in the Azov Sea region, southwest Russia. Here we present a refined chronostratigraphy and a

Substantial Accumulation of Chemically Oxidizable Organic Carbon in Continental Margin Sediments

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The balance between organic carbon (OC) sequestration and oxidation regulates the oceanic carbon cycle, and OC reactivity determines its susceptibility to remineralization or long‐term burial. However, the stability of sedimentary OC on continental margins remains poorly understood.

Le charbonnage aux XVIIe et XVIIIe siècles en Guadeloupe. Techniques, usage et dégradations des sous-sols

Archéopages
Four morphologically similar rectangular pits, dug into the Amerindian paleosol and later intersected by ravines, were identified during an extensive excavation in 2011 near the Dumanoir alley leading to the Moulin à Eau estate and sugar refinery.

Synchronous Advance of the Alpine Glaciation Across the Northern and Southern Tibetan Plateau During the Mid‐Pleistocene Transition

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...
