Resistivity Structure of the Alabama‐Oklahoma Lineament and Mississippi Embayment: Insights Into Crustal Weakness, Heat Flow, and Seismicity of the Region

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Alabama–Oklahoma Lineament (AOL) is a major crustal boundary that intersects the Mississippi Embayment (ME) and may influence intraplate deformation in the southern United States. We present the first regional magnetotelluric (MT) resistivity models across the AOL–ME system using EarthScope data and two‐dimensional inversion. All southwest–

Methodological procedure for applying geophysics to geotechnical studies in Luanda City, Angola

Minería y Geología, 2018
The use of the surface wave’s analysis in its passive and active variants was jointly assessed by the shallow seismic refraction. It allows determining dynamic parameters from the longitudinal and transverse velocities, obtained from seismic methods. For

Forward and Adjoint Calculations of Gravitational Potential in Heterogeneous, Aspherical Planets

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We have developed a computational package for the calculation of numerically exact internal and external gravitational potential, its functional derivatives and sensitivity kernels, in an aspherical, heterogeneous planet. We detail our implementation, utilizing a transformation of the Poisson equation into a spherical reference domain, as well

Passive seismic data processing methods to identify contrast intrasalt interlayers in the geological section of the Astrakhan Arch

Georesursy
The article examines the problem of processing microseismic noise (MN) to identify and evaluate occurrence depth of contrasting geological objects – intersalt interlayers with a potentially high formation pressure.

Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The process‐based surface magmatic expression of mantle plumes is typically a large igneous province (LIP) induced by the mantle plume head, followed by subsequent age‐progressive volcanic tracks resulting from plate drifting above the plume tail.

Hornblendite in the Lower Crust: A Possible Source for Porphyry Cu Deposits

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Lower crustal sulfide‐bearing Cu‐rich cumulates, mainly occurring as hornblendite, have been proposed as a critical source component for the development of giant porphyry Cu deposits (PCDs); however, their mineralogical and geochemical nature remain elusive.

The Dynamics and Surface Signal of Slab Break‐Off in Continental Settings: Insights From 3D Numerical Modeling

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The fate of an oceanic plate that has been subducted over an extended period of time involves slab break‐off, which can occur either simultaneously across the entire slab or locally, creating a tear that propagates sub‐horizontally. These processes are thought to explain various geological observations, such as the evolution of foreland basins,

Stress Model of California: Fault‐Stress Interactions Across a Complex Plate Boundary System From Focal Mechanisms of Small Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...
