Seismic wide-angle study of accreted Proterozoic crust in southeastern Wyoming [PDF]

, 1994
A seismic wide-angle xperiment was conducted in southeastern Wyoming, USA to investigate the seismic character of a postulated Proterozoic magmatic arc south of the suture (Cheyenne Belt) to the Archean Wyoming Province.

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...

Crustal structure beneath the Trondelag Platform and adjacent areas of the Mid-Norwegian margin, as derived from wide-angle seismic and potential field data [PDF]

, 2010
The outer mid-Norwegian margin is characterized by strong breakup magmatism and has been extensively surveyed. The crustal structure of the inner continental shelf, however, is less studied, and its relation to the onshore geology, Caledonian structuring,

3‐D Modeling of Differential Exhumation of Ultrahigh‐Pressure Metamorphic Rocks Driven by Increasing Plate Divergence

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Petrological and seismic constraints suggest differential sampling depth for ultrahigh pressure (UHP) metamorphic rocks exposed in different segments of the fossil subduction zone of the Western Alps. However, the mechanisms for the observed differential exhumation remain to be understood. Here, we account for the continental margin subduction

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]

, 2020
We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...

The Sumatra subduction zone: A case for a locked fault zone extending into the mantle [PDF]

, 2004
A current view is that the portion of the subduction interface that remains locked in the time interval between large interplate earthquakes, hereinafter referred to as the locked fault zone (LFZ), does not extend into the mantle because serpentinization

Project Mohole Results Enhanced With Modern XRF Core Scanning and Imaging

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Geologic collections play a fundamental role in advancing scientific discoveries, offering rich global archives reaching deep into Earth's past. Realizing the scientific potential of these remarkable resources will require the generation and curation of usable data to facilitate open science and data synthesis efforts.

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 ...

Cenozoic Subduction Polarity Reversal Within the Celebes Sea Inferred From Teleseismic Tomography

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Sulawesi and Borneo are tectonically complex islands with multistage subduction histories stretching back through the Cenozoic. Seismic studies have played an important role in helping to unravel this history, with spatial distributions of earthquakes tracking actively subducting slabs. In contrast, old or relict aseismic slabs are illuminated
