Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Soil waters are a central component of the terrestrial water cycle. Their δ2H, δ18O, and d‐excess values contain rich information about hydroclimate, including the source of moisture and its evaporative history. Paleoclimate workers seek to investigate ancient hydroclimates via triple oxygen isotope geochemistry, termed Δ′17O, which is ...

Quantifying Post‐Fire Aeolian Sediment Flux Dynamics Following the 2024 Smokehouse Creek Fire: The Role of Wind Seasonality, Thermal Clay Mineral Degradation, and Surface Armoring

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Fire in drylands is commonly associated with enhanced aeolian erosion due to the abrupt loss of vegetation cover. However, the relative contributions of fire‐induced mineralogical degradation of soils, seasonal wind forcing and surface armoring to post‐fire wind erosion remain poorly constrained.

Ichnological analysis and paleoenvironmental inferences of Neogene meandering fluvial deposits in Continental Rift of Southeastern Brazil

Brazilian Journal of Geology
The sedimentary basins in the Continental Rift of Southeastern Brazil (CRSB) provide an opportunity for ichnological analyses due to its well-known facies relationships and paleoenvironmental interpretations. This study reports invertebrate trace fossils

Response of Soils and Soil Ecosystems to the Pennsylvanian–Permian Climate Transition in the Upper Fluvial Plain of the Dunkard Basin, Southeastern Ohio, USA

Geosciences, 2018
Direct exposure of paleosols to the atmosphere during formation make them ideal for reconstructing paleoclimate. Paleosol and ichnofossil properties are dependently linked making it important to study them in tandem, to avoid errors in interpretation ...

Structural Evolution of a Polyphase Salt‐Tectonic System From Syn‐Rift Extension to Syn‐Orogenic Deformation in the Middle Atlas (Oum Er Rbia Region, Morocco)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Salt tectonics has received little attention in the Middle Atlas, despite the widespread occurrence of Triassic evaporites and their potential to exert first‐order control on basin architecture and deformation. This study presents the first integrated analysis of polyphase salt tectonics in the Middle Atlas, focusing on the Oum Er‐Rbia sector,

Urzhumian Pedocomplexes of the Kazan Volga Region (Eastern Europe): An Example of Paleoclimate and Paleolandscapes of the Subtropics of the Continental Pangea in the Middle Permian

Учёные записки Казанского университета: Серия Естественные науки
The paleosol profiles of the Urzhumian from the section on the right bank of the Volga River near the village of Grebeni were studied by field and laboratory methods. Two paleosol profiles on red clayey siltstones were identified. They were classified as

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Possible Evidence for Sea Salt Production by Solar Evaporation at a Newly Discovered Submerged Neolithic Site off the Carmel Coast, Israel

Journal of Marine Science and Engineering
The submerged Early Holocene landscape of the Carmel Coast (Israel) has yielded remarkable evidence of Neolithic settlements and their associated material culture, preserved on and within the seafloor.

First Calibration and Application of Leaf Wax n-Alkane Biomarkers in Loess-Paleosol Sequences and Modern Plants and Soils in Armenia

Geosciences, 2019
Interpreting paleoenvironmental conditions by means of n-alkane biomarker analyses is challenging because results depend on different influencing factors.

Influence of Growing Season Length on Orbital‐Scale Temperature Evolution Across the Chinese Loess Plateau

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Insight in the spatial evolution of absolute land temperature is crucial for understanding the dynamics of East Asian Summer Monsoon (EASM) precipitation, which governs the water supply for over 20% of the global population. The spatiotemporal evolution of land surface temperatures in East Asia is however not well documented.
