How environmental magnetism can enhance the interpretational value of grain-size analysis: A time-slice study on sediment export to the NW African margin in Heinrich Stadial 1 and Mid Holocene

open access: yes, 2014
Sediment dynamics in limnic, fluvial and marine environments can be assessed by granulometric and rock-magnetic methodologies. While classical grain-size analysis by sieving or settling mainly bears information on composition and transport, the magnetic ...

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 ...

The Importance of Sample‐to‐Sensor Distance in Quantitative Micro(Paleo‐)Magnetic Analysis

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Information on the past of Earth's magnetic field can be retrieved from magnetic grains in rock samples. Micromagnetic Tomography (MMT) is a recently developed method that uses magnetic surface scans from a Quantum Diamond Microscope (QDM) combined with the position of magnetic grains in rock samples to calculate the magnetic moments of those ...

Basement Geometry and Cover‐Basement Relationships in the Central‐Western Jaca‐Pamplona Basin (Southern Pyrenees): Along‐Strike Variations and Role of Structural Inheritance

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...

Astronomical forcing of the Paleogene coal- bearing hydrocarbon source rocks of the East China Sea Shelf Basin [PDF]

open access: yes, 2020
The Paleogene coal-bearing deposits (Pinghu Formation) of the Xihu Depression form the most productive hydrocarbon source in the East China Sea Shelf Basin.

Disentangling Land‐Atmosphere Interactions via Multilevel Temporal Information Partitioning Networks

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding Earth's hydrometeorological system requires characterizing the interactions at the land‐atmosphere interface. However, the multivariate nature of land‐atmosphere interactions across temporal scales and conditions remains insufficiently explored.

Variable Sensitivity of Lake Surface Temperatures to Short‐ and Long‐Term Atmospheric Warming

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Thermal sensitivity represents the magnitude of water temperature association to changes in air temperature (AT), yet global patterns in the responsiveness of lake surface water temperature (LSWT) to atmospheric warming at different temporal scales remain poorly characterized.

Temporal Change in Resistivity Structure Before and After the 2018 Small Phreatic Eruption Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...
