Cenozoic Time Constraints on the Evolution of a Gleysol‐Ferralsol‐Podzol Toposequence, Northwest Amazon Basin, Brazil

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...

A physiological approach to oceanic processes and glacial-interglacial changes in atmospheric CO2

Scientia Marina, 2008
One possible path for exploring the Earth’s far-from-equilibrium homeostasis is to assume that it results from the organisation of optimal pulsating systems, analogous to that in complex living beings. Under this premise it becomes natural to examine the

Orbital and Millennial‐Scale Cycles Paced Climate Variability During the Late Paleozoic Ice Age in the Southwestern Gondwana

Geochemistry, Geophysics, Geosystems, 2020
Orbital cycles are related to variations of Earth's orbit through time and exert profound control on glacial and interglacial climates due to changes in insolation.

Recoverability and Irreversible Information Loss in Physical Inference: Lessons From Quantum Measurement and Climate Reanalysis

Annalen der Physik, Volume 538, Issue 4, April 2026.
ABSTRACT Quantum Mechanics (QM) and Climate Science (CS) confront the epistemic problem of inferring an unobservable state from incomplete, indirect, and context‐dependent measurements. Although their physics differ profoundly (non‐commutative algebra vs.

Identification of Milankovitch Cycles and Their Sedimentary Responses in Fine-Grained Depositional Strata on the Southwestern Margin of the Songliao Basin

Applied Sciences
A series of fault depressions developed in the Kailu area on the southwestern margin of the Songliao Basin, where thick lacustrine fine-grained sedimentary rocks were widely deposited during the initial faulting stage in the Early Cretaceous.

High Geomagnetic Reversal Frequency During the Middle to Late Ediacaran (∼570 Ma) Constrained by Integrated Magneto‐ and Cyclostratigraphy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.

Milankovitch cycle of continental deep-water fine-grained sedimentary rocks in the lower submember of Es3 of Well FY1 in Dongying Sag and its significance for shale oil exploration

Energy Exploration & Exploitation, 2023
China has recently faced significant difficulties in the exploitation of its shale oil and gas resources. An essential geological obstacle preventing the breakthrough of Chinese shale oil exploration is the precise identification of productive oil and ...

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages)—a review

Boreas, Volume 55, Issue 2, Page 282-307, April 2026.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,
