The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

Sedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Obliquity-paced summer monsoon from the Shilou red clay section on the eastern Chinese Loess Plateau

Open Geosciences
The red clay of the Chinese Loess Plateau (CLP) is an important geological archive for understanding the variability in the late Neogene East Asian monsoon.

A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior. However, the geomagnetic reversal pattern during the Ediacaran–Cambrian transition remains elusive. Here we present an integrated magneto‐ and cyclo‐stratigraphic study of a ∼1.8‐Myr‐long, late

The ∼170 kyr astronomical cycle in the Early Permian Lucaogou Formation of the Junggar Basin

Frontiers in Earth Science
According to Milankovitch’s theory, periodic climate change in Earth’s history is controlled by the periodic changes in the Earth’s orbit and axis of rotation. Milankovitch cycle include eccentricity, obliquity, and precession cycles. In addition to them,

Disentangling Continental Weathering During the Late Paleozoic Ice Age

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The consumption of atmospheric CO2 through continental weathering played a critical role in shaping the evolution of the late Paleozoic Ice Age (LPIA), presumably driven by the Hercynian orogeny and the evolution of terrestrial plants. However, the relative impacts of these two major drivers to continental weathering remain poorly constrained.

Establishment of an Astronomical Time Scale and Discussion on the Sedimentary Origin of the Member 4 Glutenite, Paleogene Wenchang Formation, Enping 21 Sag, Zhu III Depression, Pearl River Mouth Basin, South China Sea

Journal of Marine Science and Engineering
Coarse-grained clastic systems in rift basins are often considered unfavorable for preserving continuous astronomical records. This study investigates the thick conglomeratic succession in the upper Member 4 (43.90–44.73 Ma) of the Wenchang Formation in ...

Reconstructing Early Cenozoic Paleodrainage and Tectonic Evolution in the Southeastern Tibetan Plateau: Evidence From Detrital Zircon and Tourmaline Provenance

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Paleogene sedimentary basins of southeastern Tibet record sediment dispersal patterns associated with crustal deformation during the early stages of the India–Asia collision. We present detrital zircon U–Pb geochronology, tourmaline geochemistry, and petrographic data from the Gonjo and Mangkang basins that suggest a reginal interconnected

Resolving allogenic forcings on shallow‐marine sedimentary archives of the Taiwan Western Foreland Basin

Sedimentology, Volume 72, Issue 6, Page 1755-1785, October 2025.
ABSTRACT An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation ...

Industrial Gamma Radiation Signals: An Untapped Resource to Reconstruct Neogene Paleoclimate Off Northwest Australia

Paleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Paleoceanographic reconstructions require both high‐resolution temporal records and high‐density spatial coverage. Scientific drilling provides detailed paleoclimate time‐series, but its spatial distribution limits our ability to capture regional climate dynamics.

Orbital-Scale Modulation of the Middle Miocene Third-Order Eustatic Sequences from the Northern South China Sea

Journal of Marine Science and Engineering
The Miocene Hanjiang Formation (HJF) is a remarkable exploration target in the Pearl River Mouth Basin (PRMB). However, challenges such as bias in current sequence stratigraphic schemes, limitations in high-resolution stratigraphic schemes, and ...
