Effects of Aging on Magnetic Mineralogy of Natural Volcanic Glass: Implications for Geomagnetic Paleointensity Recorders

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Natural volcanic glasses are well represented in the geologic record, and typically contain near‐ideal single‐domain particles required for standard Thellier‐type absolute paleointensity experiments. Young (<∼50–100 ka) glasses have been demonstrated to reliably record Earth's magnetic field.

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

Geološki 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 ...

Ferromagnetism in two mouse tumours [PDF]

, 1982
A variety of living organisms has been found recently that are biochemically able to precipitate the ferromagnetic mineral magnetite (Fe3O4). Originally discovered in the radular teeth of a primitive marine mollusc (Lowenstam, 1962), magnetite has since ...

Paleomagnetism of the Silurian-Devonian Andreas redbeds: Evidence for an Early Devonian supercontinent? [PDF]

, 1988
Two components of magnetization were isolated in the Silurian-Devonian Andreas redbeds of the central Appalachians of Pennsylvania (lat 40.75 degrees N, long 75.78 degrees W): a thermally distributed, synfolding B component, and a thermally discrete, pre-

Regional Three‐Dimensional Magnetotelluric Electrical Resistivity Model of the Manica Greenstone Belt, Western Mozambique

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Magnetotelluric (MT) survey results from the Late Archean Manica greenstone belt, an extension of the Odzi‐Mutare greenstone belt of the Zimbabwe Craton, are presented. A total of 33 MT stations were acquired on an irregular grid with an average station spacing of approximately 5 km.

Palaeomagnetism and tectonics of middle America and adjacent regions Part 1

Geofísica 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 ...

Increasing the Accuracy and Efficiency of Micromagnetic Tomography by Double Sided Scanning

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Paleomagnetic data are usually retrieved by subjecting bulk samples, for example lavas, to laboratory measurement protocols. In many instances, the data related to these protocols yield uninterpretable results caused by the presence of particles with adverse magnetic properties that blur the signal of the reliable magnetic particles.

Site 1216

, 2002
Site 1216 (21°27.16´N, 139°28.79´W; 5152 meters below sea level [mbsl]; Fig. F1) is situated in abyssal hill topography south of the Molokai Fracture Zone and two small associated unnamed parasitic fracture zones (Fig. F2).

Hydroacoustic Observations of the 15 January 2022 Hunga Tonga‐Hunga Ha'apai Eruption: The Role of Bathymetry Along the Path

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The 15 January 2022 submarine volcanic eruption of Hunga Tonga‐Hunga Ha'apai released immense energy throughout the ocean, solid Earth, and atmosphere. We analyze mid‐oceanic column acoustic pressure recordings from 24 freely drifting Mobile Earthquake Recorder in Marine Areas by Independent Divers sensors, and from 11 moored hydrophones in ...

Influence of inclination error in sedimentary rocks on the Triassic and Jurassic apparent pole wander path for North America and implications for Cordilleran tectonics [PDF]

, 2010
Because of paleomagnetic inclination error (I error) in sedimentary rocks, we argue that previous estimates of Triassic and Jurassic paleolatitudes of the North American craton have generally been too low, the record being derived mostly from sedimentary
