Trends in Modern Tectonic Evolution of the Doubled Transform Fault Charlie Gibbs (North Atlantic)

Tectonic Evolution of the Mariana Trough

The Mariana Trough is an active back‐arc basin formed by subduction of the Pacific Plate beneath the Philippine Sea Plate and provides an ideal setting for investigating the evolution of back‐arc basins. In this study, we compile bathymetric, magnetic, and gravity data to reconstruct the formation history of the entire...

Modulation of Crustal and Mantle Flow Systems by a Cratonic Root in NE Tibet and Western North China Craton: Evidence From Seismic Azimuthal Anisotropy Analysis

The northeastern Tibetan Plateau (TP) and the western North China Craton (NCC) provide a natural laboratory for studying the interaction of tectonic and mantle processes, contrasting the active plateau with the stable craton. In contrast to many prior studies that relied on station‐averaged shear‐wave splitting (SWS) m...

Geodynamic Significance of Intraplate Basaltic Magmatism From the Western Mediterranean Region

Dynamic topography changes as mantle convection evolves, making its past surface expression difficult to reconstruct. Widespread Neogene‐Quaternary intraplate basaltic magmatism across the Western Mediterranean Region allows us to test whether dated basalts preserve the mantle thermal structure responsible for region...

Asthenospheric basal drag primarily drives the Pacific Plate

Introduction: Previous geodynamic studies have indicated the dynamic importance of positive buoyancy in the mantle beneath the eastern Pacific in driving the Pacific Plate. However, it is not well understood whether the shallower or deeper low-seismic-velocity regions of the mantle are involved in the motion and the in...

Analysis of upper mantle anisotropy in the North China Craton using SKS-wave splitting measurements

A Sharp Melt‐Bearing Lithosphere–Asthenosphere Boundary Beneath the Korean Peninsula: Evidence From Teleseismic Receiver Functions

The lithosphere–asthenosphere boundary (LAB) provides key constraints on how continental lithosphere responds to tectonic processes. Located between the East Asian cratonic blocks and the western Pacific subduction system, the Korean Peninsula (KP) provides an important setting to examine continental lithospheric evolu...
