GEOPHYSICAL AND PETROLOGIC INVESTIGATIONS OF INVERSELY CORRELATED AEROMAGNETIC AND BOUGUER GRAVITY ANOMALIES WITHIN PRECAMBRIAN GNEISS TERRANE NEAR GARVIN, SOUTHWESTERN MINNESOTA

open access: yes, 2023
Geophysical models and petrologic inferences presented here are consistent with a buried gabbroic to noritic intrusion as the principal source of two geographically coincident, kilometer-scale, inversely correlated gravity and magnetic anomalies (the ...

Bouguer and aeromagnetic anomalies in the Iberian Chain (NE Spain); a qualitative interpretation

open access: yesGeogaceta
This work shows the Bouguer and aeromagnetic anomaly maps of the Iberian Chain (NE Spain) and surroundings in relation to its main geological and structural units. In general, both gravity and aeromagnetic anomalies are aligned following the same trends

Post‐Miocene Transtensional Opening of the Northern Red Sea

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The mechanism of opening, as well as the crustal characteristics of the northern Red Sea are subject of ongoing controversial scientific debate. With the objective of elucidating the nature of rifting in this area, a grid of 2D multi‐channel reflection seismic data was acquired off the Al Wajh carbonate platform (AWCP), and supplemented by ...

The Analysis of the Gravity Anomalies of Arizona

open access: yes, 1976
The Bouguer correction using a mean sea level reduction datum compensates the gravitational effect of the mass of the terrain above sea level. This correction generally results in long -wavelength Bouguer gravity anomalies if the mass of the terrain is ...

The Effects of a Microplate on Plume‐Ridge Interactions: Constraints From Comparing Easter and Juan Fernandez Microplates in the Eastern Pacific Ocean

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract This study investigates the nature of plume‐ridge interactions near a tectonic microplate using mantle Bouguer anomaly (MBA) gravity calculations. The focus of this investigation is a comparison of the Easter and Juan Fernandez microplates, which are located in the eastern Pacific Ocean along the Pacific, Nazca, and Antarctic plate boundaries.

Seismic Reflection Profiling at the Kentland Impact Structure, Indiana: Geophysical Characterization of Impact Induced Damage

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The Kentland Impact Structure is a classic complex crater whose central peak is exposed in an active quarry in NW Indiana, USA. However, its diameter has remained poorly constrained due to the thick glacial sediment cover. Newly obtained seismic reflection profile images combined with refraction seismic tomography, earlier gravity surveying ...
