Paleomagnetism of the Late Paleogene and Neogene rocks of the Serbian Carpatho-Balkanides: Tectonic implications [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2002
This paper focuses on results of the paleomagnetic research conducted in the territory of Serbian Carpatho-Balkanides, within the following basinal domains: Babušnica-Koritnik (the Oligocene deposits), Žagubica (the upper part of the Lower Miocene and ...

Rapid UAV‐ and Ground‐Based Magnetic Mapping of Subsurface Fractures During a Volcano‐Tectonic Crisis in Grindavík, Iceland

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We applied an integrated UAV‐ and ground‐based magnetometry workflow to map shallow subsurface fractures and cavities in the town of Grindavík during the 2023–2025 volcano‐tectonic crisis. Short‐wavelength linear and semi‐circular magnetic lows delineate open or partially open fractures and localized cavities, including features with no ...

Vanadium Isotopic Compositions of the High‐3He/4He Baffin Island Lavas

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The isotopic composition of vanadium (V) in hotspot lavas provides new insight into the source of deep mantle heterogeneities. We measured V isotopic compositions in Paleogene Baffin Island lavas, which erupted above the Iceland plume head, to constrain the mantle plume source. These lavas have V isotopic compositions that are lighter (−0.96 ±

Palaeomagnetism and tectonics of middle America and adjacent regions Part 1

open access: yesGeofísica Internacional, 1981
Investigations, unified under the working hypothesis of plate tectonics, have produced a revolution in the earth sciences over the past decades. The effects of this have been profound since it has lead to a reexamination of the vast amount of available ...

Constraining the Permeability and Outer‐Rise Hydration at the Central America Margin

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Subduction zones are important drivers of Earth's geochemical evolution; the presence of water within the subduction system has substantial implications for geohazards, including the style of seismicity and the volume of magma generated at arc volcanoes.

Inferring the Base of Submarine Permafrost in the Canadian Beaufort Sea From Seismic Data and the Depth of the Gas Hydrate Stability Zone

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The widespread presence of submarine permafrost in the southern Canadian Beaufort Sea provides necessary stability conditions for gas hydrates on the shallow shelf. However, the submarine permafrost is still relatively underexplored. Representing mostly relict terrestrial permafrost, submarine permafrost was formed by subaerial exposure to ...

Emplacement Conditions and Alteration of Volcanic Deposits Inferred From Magnetic Properties of the ICDP Eger Drill Site S4 (Bažina Maar), Czechia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Titanomagnetite in alkaline maar deposits exhibits variable syn‐ and post‐crystallization alteration linked to wet emplacement and groundwater fluctuations, which remain poorly documented. Magnetic and mineralogical analyses of lapilli, scoria, and basalt from ICDP Eger drill cores S4 and S4b (Bažina maar, western Eger Graben, Czechia) reveal ...

Paleomagnetism

open access: yesEos, Transactions American Geophysical Union, 1989
The Third Annual Northeast Paleomagnetic Workshop was held September 23 at the University of Massachusetts, Amherst; Laurie Brown of the university's geology department was the organizer. On September 22, Sue Halgedahl of Lamont Doherty Geological Observatory, Palisades, N.Y., gave a lecture on magnetic domain structure and its relationship to ...
