Accretionary Prism and Forearc Deformation Driven by the Beata Ridge Indentation in Southern Hispaniola: Insights From the Offshore San Pedro Basin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...

Rock magnetic investigation of possible sources of the Bangui magnetic anomaly

open access: yes, 2013
International audienceThe Bangui magnetic anomaly (BMA) is the largest lithospheric magnetic field anomaly on Earth at low latitudes. Previous studies investigated its geological source using constraints from satellite and ground magnetic field ...

LCS-1: A high-resolution global model of the lithospheric magnetic field derived from CHAMP and Swarm satellite observations [PDF]

open access: yes, 2017
We derive a new model, named LCS-1, of Earth’s lithospheric field based on four years (Sept 2006 – Sept 2010) of magnetic observations taken by the CHAMP satellite at altitudes lower than 350 km, as well as almost three years (April 2014 to December 2016)

A Machine Learning Approach for Volcanic Eruption Mass Estimation

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Estimation of total volcanic erupted mass—the primary metric of eruption magnitude—is typically performed post‐eruption relying on dense monitoring of ground‐based seismology, gravity and deformation instrumentation, and therefore exists for only ∼100 of ∼1280 volcanoes worldwide.

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

open access: yesEarth 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–

Digital image processing and isostatic studies of the regional gravity field of Great Britain and adjacent marine regions [PDF]

open access: yes, 1988
This thesis presents the results of an investigation into the regional gravity field of Great Britain and the adjacent regions. A prerequisite for this study was the development of a computer database designed to store, manipulate and display the ...

Correlation between lithospheric magnetic anomalies and tectonic structures in the Norwegian-Greenland region of the Arctic

open access: yesGeodynamics & Tectonophysics, 2018
The studies of the deep structure and tectonics of the Arctic are important for solving the fundamental problems of modern geodynamics and developing its natural resources. This region is also of interest from the geopolitical point of view, in particular, considering the boundaries of the marginal seas.

Anomalously Low 3He/4He and Elevated Heat Flow in the Northern Apennines Explained by Lithospheric Delamination: A Modeling Approach

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The 3He/4He ratios measured in 12 CO2‐dominated gas seeps from the Tuscany‐Roman Volcanic Provinces in Italy range between 0.07 and ∼1.6 Ra. Helium and δ13CO2 isotope systematics indicate a dominant crustal source with a variable but significantly lower contribution from the mantle.

Statistical prediction of satellite magnetic anomalies

open access: yes, 1990
The geological utility of satellite magnetic observations is limited by orbital altitude variations which may be as large as a few hundred kilometres. This study investigates the use of fast and elegant statistical procedures for altitude normalization ...

Characterisation of the Magnetic Mineralogy, Properties and Magnetic Anomaly Responses of two Garnetiferous Peridotite Bodies in the WGR, Otrøya: Ground Magnetic Surveying, Sampling, Magnetic Characterisation and 2D Modelling [PDF]

open access: yes, 2014
Information on magnetisation of earth s crust comes from the study of magnetic anomalies measured at various elevations using ground, airborne and satellite data, as well as studies of deep-seated rocks exposed at the surface.
