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

, 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 ...

Algorithmic and methodological aspects of transformftion of regional gravity anomalies (on the example of the Kuril island arc)

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
The technique of transforming gravity anomalies for large areas, which uses geodetic coordinates of field points and takes into account the spherical shape of the Earth, is considered.

Improved Half‐Space Cooling Model Reconciles Bathymetry and Thermal Evolution of the Southwest Subbasin, South China Sea

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The bathymetry of marginal sea basins commonly deviates from depths calculated by classical lithospheric cooling models, yet the controlling mechanisms remain debated. Here, using 19 seismic profiles and corrected local heat‐flow data, we apply an improved half‐space cooling model within a two‐stage reconstruction to reassess thermal ...

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Multi‐Scale Spatial Variations in Pacific Mantle Seismic Anisotropy: Constraints on Plate Evolution and Asthenospheric Flow

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...

Coupling Seismic, Gravity and Magnetic Surveys for the Investigation of Planetary Lava Tubes: A Terrestrial Analog Case Study in Lanzarote (Spain)

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

Crustal structure of the spreading plate boundary in Iceland and the north Atlantic from gravity data [PDF]

, 1994
Gravity datasets from two geothermal areas in Iceland, an Iceland-wide gravity dataset, and marine gravity data from the Reykjanes Ridge at 58˚N, which can be seen as the submarine extension of the Icelandic accretionary system, have been studied in this

Asymmetric Ilmenite‐Bearing Cumulates Triggered Lunar Dichotomic Volcanism on the Nearside and Farside

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The cause of the observed mare basalt asymmetry between the lunar nearside and farside remains a long‐lasting conundrum. In this study, we characterized the petrology and geochemistry of the Chang'e‐6 low‐Ti basalts from the lunar farside, performed petrological modeling of major elements and conducted Monte Carlo simulation of trace elements,

Residual Bouguer satellite gravity anomalies reveal basement grain and structural elements of the Vøring Margin, off Norway [PDF]

, 2002
Free-air gravity data from satellite altimetry and ship-track derived bathymetry data are used to calculate a residual Bouguer gravity anomaly map for the mid-Norwegian Margin.

The Internal Ice Content of Timpanogos Rock Glacier, Utah, USA From 3‐D Bayesian Inversion of Gravity Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Despite the prevalence of rock glaciers in mountain environments, their ice volumes are poorly constrained. Rock glaciers persist in settings unable to support glaciers. They act as climate resilient water stores and refugia for cold‐adapted species while also posing a hazard to alpine communities. Imaging the entire internal structure of rock
