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 ...

Application of High‐Precision Microgravity Detection Technology in the Exploration of Ultradeep Gas Reservoirs in the Middle Part of the Southern Margin of Junggar Basin

Geofluids, Volume 2026, Issue 1, 2026.
This study is aimed at identifying the ultradeep gas reservoir structure and gas‐rich areas in the middle section of the southern margin of the Junggar Basin. Based on high‐precision microgravity data collected from the complex terrain areas of Huxi and Tudong in the middle section of the southern margin of the Junggar Basin, residual gravity anomalies

Formation of Caloris Basin's Positive Mass Anomaly by Thermal Contraction During Its Postimpact Evolution

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Caloris basin preserves a record of Mercury's volcanic and tectonic activity, including the long‐wavelength warping of its surface in the north‐south direction. As Mercury's largest mascon basin, identifying Caloris' configuration prior to volcanic infilling is a key step in determining the series of events that led to its current state. Here,

Gravimetric determination of the continental oceanic boundary of the Argentine continental margin (from 36°S to 50°S) [PDF]

, 2016
This paper presents the gravimetric analysis together with seismic data as an integral application in order to identify the continental?oceanic crust boundary (COB) of the Argentine continental margin from 36◦S to 50◦S in a continuous way.

A Novel Iterative Stable Algorithm for Global Moho Modeling in the Spherical Harmonic Domain

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The Mohorovičić discontinuity (Moho) marks the boundary between Earth's crust and the underlying mantle, serving as a critical interface for understanding Earth's structure, composition, and geodynamic processes. This study introduces a novel iterative and stable algorithm for global Moho depth inversion.

Geophysical Insights Into 3D Crustal Architecture of Jurassic Magmatic Intrusions in the Moroccan Atlas

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Magmatic intrusions in rifted continental margins play a critical role in shaping structural evolution, yet their geometry and emplacement mechanisms remain poorly constrained in salt‐influenced terrains. The Moroccan Central High Atlas, a segment of the Atlas fold‐and‐thrust belt, hosts extensive Middle Jurassic to Early Cretaceous intrusions

Upgraded map of Bouguer anomalies of Lithuania based on GIS techniques

Geodesy and Cartography, 2012
The presently used Bouguer anomaly map of Lithuania is based on gravity field mapping of 1958-1961. The constant density 2,30 g/cm3 between the Earth’s surface and reference level (sea level) was employed to calculate Bouguer anomalies. The digital model

Tectonic Framework of the Arenópolis and Anicuns‐Itaberaí Segments of the Goiás Magmatic Arc Based on 3D Magnetotelluric Inversion

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The Goiás Magmatic Arc (GMA) is a Neoproterozoic juvenile terrain formed through oceanic‐oceanic and oceanic‐continental subduction. It comprises three main segments: Mara Rosa, Anicuns‐Itaberaí (GMAAI), and Arenópolis (GMAA), whose tectonic evolution and connectivity remain uncertain.
