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

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 ...

Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, Volume 37, Issue 14, Page 10174-10186, 30 August 2026.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

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

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 ...

The Phanerozoic Four Revolutions and Evolution of Paleosol Ichnofacies

, 2016
The analysis of a database composed of 166 cases of invertebrate and root trace fossils in paleosols allowed us to recognize four major evolutionary steps in the Phanerozoic evolution of paleosol ichnofaunas.

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.
