Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

open access: yesTerra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

3D Quantification of Subsidence During Pyrenean Retro‐Wedge Initiation: Role of Structural and Thermal Inheritance on Hyperextended Margin Inversion (Aquitaine Basin)

open access: yesTerra Nova, Volume 38, Issue 2, Page 130-140, April 2026.
ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

Interplay of Tectonics and Topography Facilitated Sudden Dyke Intrusion in 2022 at São Jorge Island, Azores

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Oblique slow rifting in a hotspot setting has created a distributed volcanic zone in the central part of the Azores but it's unclear what causes focusing of magma upflow under the islands within a wide plate boundary deformation zone. For São Jorge Island, we use a three‐dimensional finite element model to evaluate crustal stress from the ...

Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction. Detailed lithospheric structure is essential to explain craton destruction.

A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...
