Role of Complex Crustal and Basinal Structures in Onset of an Intracratonic Rift System: An Example From the Onshore Potiguar Basin, Brazilian Equatorial Margin

Basin Research, Volume 38, Issue 2, March/April 2026.
Schematic evolution model of the Onshore Potiguar Basin, illustrating the role of complex crustal and basinal structures in the onset of this intracratonic rift system in NE Brazilian Equatorial Margin. Red arrows indicate the extensional direction and coloured areas on the surface are the Self‐Organizing Maps populations related to crystalline ...

Describing the Global Gravity Field of Mars With Lithospheric Flexure and Deep Mantle Flow

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The volcanic complex Tharsis Region on Mars is known for its numerous volcanoes on top of the crust, elevated topography (doming), and a long‐wavelength gravity anomaly correlated with the region. Flexural modeling of the lithosphere has commonly been used to understand the relationship between observed topography, crustal structure, and ...

Lithospheric strength of the Anatolian plateau and implications for strong earthquake activity in Turkey

Geodesy and Geodynamics
On February 6, 2023, the doublet earthquake including two main shocks with magnitudes MW7.8 and MW7.5, occurred near the western side of the East Anatolian Fault at the southeast boundary of the Anatolian Plateau in Turkey.

Regional geochemical and geophysical surveys in the Berwyn Dome and adjacent areas, north Wales [PDF]

, 1984
This report describes stream sediment and gravity surveys carried out across the Berwyn Dome and adjacent areas. The gravity survey confirmed the presence of a broad regional Bouguer anomaly low in the central part of the Dome, on which is ...

Morphological Evolution of Impact Craters and Associated Gravity Anomalies: New Perspectives From Numerical Modeling

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Hyper‐velocity impacts on planetary surfaces lead to impact craters whose morphology evolves due to exogenous factors such as atmospheric processes, as well as endogenous factors including tectonic and metamorphism. On Earth, erosion processes driven by climate (fluvial, aeolian, glacial processes) progressively erase these structures, or even

Origin of the Bulge Topography Within Caloris Basin, Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.

3-D lithospheric structure and regional/residual Bouguer anomalies in the Arabia-Eurasia collision (Iran) [PDF]

, 2013
The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia-Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components.

Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Magma storage in a strike-slip caldera [PDF]

, 2016
Silicic calderas form during explosive volcanic eruptions when magma withdrawal triggers collapse along bounding faults. The nature of specific interactions between magmatism and tectonism in caldera-forming systems is, however, unclear.
