Updated Iberian Archeomagnetic Catalogue: New Full Vector Paleosecular Variation Curve for the Last Three Millennia

Geochemistry, Geophysics, Geosystems, 2018
In this work, we present 16 directional and 27 intensity high‐quality values from Iberia. Moreover, we have updated the Iberian archeomagnetic catalogue published more than 10 years ago with a considerable increase in the database.

Hydrodynamic variations and human activities have influenced sediment fluxes in the pearl river delta since the late holocene

Frontiers in Earth Science, 2023
Climate change and human activity can both exert a role in the river discharge and sediment load in river deltas when the sea level remains relatively stable.

Paleomagnetic Constraints on the Separation of the Olongbuluke Block From the North China Block During the Late Cambrian–Middle Ordovician and Its Tectonic Significance

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.

Rapid Changes in Strength and Direction of Earth's Magnetic Field Over the Past 100,000 Years

Geochemistry, Geophysics, Geosystems
Previous studies of rapid geomagnetic changes have highlighted the most extreme changes in direction and field strength found in paleomagnetic field models over the past 100 ky. Here we study distributions of rates of change in both time and space. Field

Secular variation and excursions of the Earth magnetic field during the Plio-Quaternary: New paleomagnetic data from radiometrically dated lava flows of the Colima volcanic complex (western Mexico)

Revista Mexicana de Ciencias Geológicas, 2018
Detailed rockmagnetic and paleomagnetic investigations were performed on selected lava flows from the Colima volcanic complex (CVC) located in the western sector of the Trans-Mexican Volcanic Belt. Reliable paleomagnetic directions were obtained from 21

Influence of Data Filters on the Position and Precision of Paleomagnetic Poles: What Is the Optimal Sampling Strategy?

Geochemistry, Geophysics, Geosystems, 2022
To determine a paleopole, the paleomagnetic community commonly applies a loosely defined set of quantitative data filters that were established for studies of geomagnetic field behavior. These filters require costly and time‐consuming sampling procedures,

Paleomagnetic Evidence of Internal Rotation in the Eastern Qiangtang and Its Relation to Distributed Strike‐Slip Faulting in the Southeastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The southeastern Tibetan Plateau has undergone complex deformation due to the India‐Eurasia collision. Although late‐stage internal rotations are documented in the Lanping‐Simao Terrane to the south, it remains unclear whether similar processes have affected the north.

Northeastern Greenland Paleomagnetic Records Indicate the Influence of Geomagnetic Flux Lobe Intensity on Virtual Geomagnetic Pole Migration During the Holocene

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Paleomagnetic and rock magnetic analyses were conducted on sediment cores from the northeastern Greenland Shelf and Young Sound along the western edge of Fram Strait. The paleomagnetic signal in all three sediment cores is characterized by a strong and stable single component magnetization carried by low coercivity ferrimagnetic single domain ...

Kinematics of Burial Remagnetizations in Fold‐and‐Thrust Belts: A Case Study From the South Pyrenean Foreland Basin (NE Spain)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract This study investigates two burial‐related remagnetizations in the Jaca–Pamplona foreland basin (Southern Pyrenees): one with dual polarity and a positive reversals test, and another with only reverse polarity. These components, labeled C3 and C4 based on their mean unblocking temperatures, were identified from a paleomagnetic analysis of 142 ...
