Computation of a combined spherical-elastic and viscous-half-space earth model for ice sheet simulation [PDF]

, 2006
This report starts by describing the continuum model used by Lingle & Clark (1985) to approximate the deformation of the earth under changing ice sheet and ocean loads.

Multiscale Analysis of Bouguer Gravity Anomalies: Unveiling the Deep Structure of Eastern Himalayan Syntaxis Faults

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Eastern Himalayan Syntaxis (EHS), which is located at the southeastern edge of the Qinghai–Xizang Plateau, is a key region for understanding mountain‐building and subduction processes. Bouguer gravity anomalies derived from the Earth Gravitational Model 2008 free‐air anomaly data following topographic corrections, were analyzed.

Melt infiltration of the lower lithosphere beneath the Tanzania craton and the Albertine rift inferred from S receiver functions

Geochemistry, Geophysics, Geosystems, 2012
The transition between the lithosphere and the asthenosphere is subject to numerous contemporary studies as its nature is still poorly understood. The thickest lithosphere is associated with old cratons and platforms and it has been shown that seismic ...

Structure of the upper mantle in the north-western and central United States from USArray S-receiver functions [PDF]

, 2015
We used more than 40 000 S-receiver functions recorded by the USArray project to study the structure of the upper mantle between the Moho and the 410 km discontinuity from the Phanerozoic western United States to the cratonic central US.

Lithospheric Mantle Heterogeneity Drives Delayed Magmatism and Wide Continent‐Ocean Transitions in Rifted Margins

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The formation of wide, magma‐starved continent–ocean transition (COT) zones remains incompletely understood. We use 2‐D thermo‐mechanical numerical experiments, coupling hydrous mantle melting with parameterized crustal accretion, to explore controls on magmatic lag: the delay between continental crustal break‐up and steady oceanic crustal ...

New Insights Into the Cooling of the Oceanic Lithosphere From Surface‐Wave Tomographic Inferences

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract How oceanic plates cool and thicken with age remains a subject to debate, with several thermal models supported by apparently contradictory data. Combining a novel imaging technique that balances resolution and uncertainty with finite‐frequency surface‐wave measurements, we build tomographic model SS3DPacific to revisit the cooling style of ...

The Indian Plate subducting below the Tibet Plateau is tearing apart

Communications Earth & Environment
The first-order configuration of the Himalayan orogen is defined by northward motion of the Indian plate, whether directly underplating Tibetan crust or subducting beneath a mantle wedge.

Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

Self‐Consistent Models of Earth's Mantle and Core From Long‐Period Seismic and Tidal Constraints

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Here we illustrate the use of parameterized models to address fundamental questions about Earth's mantle and core structure. For this, we invert a large set of normal‐mode center frequencies and quality (attenuation) factors, along with astronomic‐geodetic data, for the radial anelastic seismic structure of the Earth.

Seismic Discontinuities Across the North American Caribbean Plate Boundary From S‐to‐P Receiver Functions

Geochemistry, Geophysics, Geosystems, 2021
The evolution of the Caribbean plate has resulted in the formation of volcanic arcs, the Caribbean Large Igneous Province (CLIP) and micro‐plates across the plate boundary zones.
