Late Glacial–Holocene climatic transition record at the Argentinian Andean piedmont between 33 and 34° S [PDF]

Climate of the Past, 2014
The Arroyo La Estacada (~ 33°28' S, 69°02' W), eastern Andean piedmont of Argentina, cuts through an extensive piedmont aggradational unit composed of a dominant Late Pleistocene–early Holocene (LP–EH) alluvial sequence that includes several paleosols ...

Fault‐Related Carbonates as Quaternary Seismotectonic and Paleoclimate Archives (Monte Marine Fault, Central Apennines)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seismogenic faults shape continental landscapes, drive crustal deformation and influence fluid exchange between the lithosphere and atmosphere. Yet, quantitative links between fault activity, exhumation and near‐surface environmental evolution remain poorly understood. Here, structural (meso‐ and micro‐scale) investigations are integrated with

Relief in Aeolian Environment. The Surface of Nida Settlement

Archaeologia Lituana, 2019
During archaeological investigations in Nida settlement in 1974–1978, 2011–2013 and 2016 a lot of stratigraphic data from considerably wide area was gathered.

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

Sedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.
ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

The Altitude Effect of Stable Isotopes in Rivers Over the Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The altitude effect of stable isotopes in river water is key to paleoelevation reconstruction, yet remains poorly quantified at regional scales due to monitoring challenges. This study compiled river water isotope data across the Tibetan Plateau and used a decision‐tree‐based random forest model to simulate high‐resolution δ18O patterns.

Quaternary pedostratigraphy of the Nevado de Toluca volcano

Revista Mexicana de Ciencias Geológicas, 2018
Paleosol sequences of the Nevado de Toluca volcano (NTV) preserve a detailed record of late Quaternary environmental change. In fact, some studies have been used the NTV paleosols to interpret paleoenvironmental conditions, however some uncertainties ...

Ecological and Hydrological Modulation of Land Surface Temperature in the East Asian Monsoon Margin During Pliocene‐Pleistocene Global Cooling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The response of terrestrial climate to future warming remains debated. The Pliocene, with CO2 levels similar to today, is an important analog for the future. The East Asian monsoon marginal region is one of the most climate sensitive regions on Earth. Based on contemporaneous aeolian sediments and aquatic‐influenced alluvial sediments from the

The Difference in Shear Behavior and Strength between Loess and Paleosol and Their Prediction of Unsaturated Strength

Applied Sciences
In recent decades, loess landslide events have attracted increasing attention in the South Jingyang tableland. To elucidate the mechanical mechanism of landslide initiation in the region, this work collected undisturbed loess and paleosol samples taking ...

The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.

Radiocarbon Reveals Modern Carbon Exchange With Topsoil Inorganic Carbon in Drylands

Global Change Biology, Volume 32, Issue 9, September 2026.
Radiocarbon measurements across drylands reveal that topsoil inorganic carbon carries a measurable modern carbon signature linked to soil pH and organic carbon pools. This modern imprint weakens with increasing aridity and soil depth, indicating reduced exchange with contemporary carbon sources under drier conditions and in deeper soils.
