Uplift of the Transantarctic Mountains: Evidence for an Evolving and Long‐Lived Rayleigh‐Taylor Instability

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Rayleigh‐Taylor instabilities within the upper mantle are investigated as a mechanism for the uplift of rift‐margin mountain ranges within the continents. Our focus is on the Transantarctic Mountains (TAM). These mountains form at the margin between East and West Antarctica and have been free from the effects of subduction for about 500 ...

DEEP-SEATED BOUNDARY STRUCTURES OF THE SIBERIAN CRATON AND THE BAIKAL-PATOM FOLD-AND-THRUST BELT IN THE CROSS-SECTION OF THE 1-SB-VOSTOCHNY PROFILE AND ITS CONTINUATION ALONG THE VITIM RIVER

open access: yesГеодинамика и тектонофизика
The deep-seated boundary structures of the Siberian craton and the Baikal-Patom fold-and-thrust belt have been considered in the cross-section of the 1-SB-Vostochny reference geophysical profile and its continuation along the Vitim River.

Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Two Distinct Growth Styles of Riedel Shear Zones in Cratonic Strike‐Slip Fault System, Tarim Basin, NW China

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Cratons Through the Ages: Impact of Rayleigh Number on Craton Shape

open access: yes, 2023
Cratonic lithosphere contains crucial details about planetary dynamics on Earth and understanding the shape of cratonic lithosphere may provide new insight into their history. Seismic imaging suggests that there are various margin shapes of the present day cratonic lithosphere, including regions with vertical or sloped margins. While prior studies have

Attention and Geological Knowledge Guided Spectral‐Spatial Networks for Geochemical Anomalies Recognition

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Achieving both accuracy and interpretability in deep learning models for geochemical anomaly recognition constitutes a significant challenge. To overcome this challenge, this study developed a novel interpretable dual‐branch network combining a spectral attention bidirectional RNN (BiRNN) branch and a spatial attention CNN branch guided with ...

Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

SOUTHEASTERN MARGIN OF THE SIBERIAN CRATON – DEEP STRUCTURE AND LATE MESOZOIC GEODYNAMICS

open access: yesГеодинамика и тектонофизика
The 3-DV seismic profile data interpretation was used to obtain a geodynamic model for the deep structure of the southeastern margin of the Siberian craton and the South Verkhoyansk sector of the Verkhoyansk fold and thrust belt (VFTB).
