Seismic Constraints on Temperature, Partial Melt, and Lithosphere‐Asthenosphere Dynamics in the Southwestern United States

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The southwestern United States hosts well‐documented and dramatic variations in topography, seismicity, heat flow, magmatism, and seismic velocity structure. This region offers opportunities to investigate how processes such as temperature and partial melt are related to the Lithosphere‐Asthenosphere Boundary (LAB), and how they ultimately ...

Crustal structure and high-resolution Moho topography across the Rwenzori region (Albertine rift) from P-receiver functions [PDF]

Geological Society, London, Special Publications, 2015
Abstract The Rwenzori region, which is located between the Democratic Republic of Congo and Uganda, is part of the western branch of the East African Rift. With elevations of c. 5000 m a.s.l., the Rwenzori Mountains are situated between the Albert Rift and the Edward Rift segments and cover an area of ...

Nature of the Crust in the Superdeep Bengal Basin Using Teleseismic P Waves

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Bengal Basin is a sedimentary basin in the northeast region of the Indian subcontinent. It lies between the Indian Shield and the Indo‐Burma Ranges, where the India plate is obliquely subducting under the Burma microplate. Multiple interpretations of the nature of the crust here have been proposed.

Inversion of satellite gravimetric data from Recôncavo-Tucano-Jatobá Basin System

Brazilian Journal of Geology, 2020
Density differences among subsurface rocks cause variations in the gravitational field of Earth, which is known as gravity anomaly. Interpretation of these gravity anomalies allows assessment of the probable depth and shape of the causative body.

Plate Interactions and Mantle Flows Beneath the Caribbean and Adjacent Regions Revealed by P‐Wave Anisotropic Tomography

Tectonics, Volume 45, Issue 3, March 2026.
Abstract We determine the first P‐wave azimuthal and radial anisotropy tomography beneath the Caribbean and its adjacent regions. The Cocos and Atlantic Plates are imaged as high‐velocity (high‐V) zones down to ∼1,600 km depth and they have subducted independently beneath the Caribbean Plate.

Lithospheric Seismic Structure of the Anatolian Plate and Its Implications for Plateau Uplift: Evidence From Joint Inversion of Receiver Functions and Surface Waves

Geochemistry, Geophysics, Geosystems
High topography (>1 km) on the Anatolian Plate is widely attributed to buoyant mantle support, not just the isostatic response of crustal shortening.

Thick Crust at Earth's Slowest Spreading Ridge: 3D Gravity Insights From Eurasian Basin, Arctic Ocean

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Eurasian Basin of the Arctic Ocean opened by ultraslow spreading along the Gakkel Ridge, yet crustal thickness has remained poorly constrained due to sparse seismic data. We present a new basin‐wide 3‐D gravity model, updated by the most comprehensive sediment thickness and seismic observations, offering the first systematic view of ...

On the Construction of Moho Reflected Shear Wave Phases From Ambient Noise

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Shear waves reflected from the Moho (SmS) are frequently identified in ambient noise cross‐correlation functions. Despite their consistent appearance across various arrays and studies, the physical origin and generation mechanisms of these SmS phases remain poorly understood.

Moho topography beneath the Iberian-Western Mediterranean region mapped from controlled-source and natural seismicity surveys

Tectonophysics, 2016
The complex tectonic interaction processes between the European and African plates at the Western Mediterranean have left marked imprints in the crustal architecture of this area, particularly concerning the lateral variations in crustal thicknesses. The detailed mapping of such variations is hence of large interest, as it provides a major constraint ...

Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift
