Enriching Paleogeographic Reconstruction Through the Integration of Bayesian Age Models Into Site‐Based Apparent Polar Wander Paths

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Apparent polar wander paths (APWPs) synthesized from paleomagnetic data are foundational to our understanding of the long‐term motions of lithospheric plates. Recent progress has highlighted the advantages of developing such paths from paleomagnetic sites that provide individual snapshots of the ancient geomagnetic field.

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.

Paleomagnetism of late Cretaceous dykes in the Gangdese belt: New constraints on the position and structure of the southern margin of Asia prior to the India-Asia collision

China Geology, 2023
: This paper report paleomagnetic data from late Cretaceous diorite dykes that sub-vertically intrude granodiorites in the eastern Gangdese belt near the city of Lhasa. Our research goals are to provide further constraints on pre-collisional structure of

Spectral analysis and modeling of microcyclostratigraphy in late Paleozoic glaciogenic rhythmites, Paraná Basin, Brazil

Geochemistry, Geophysics, Geosystems, 2011
We investigate the depositional time scale of lithological couplets (fine sandstone/siltstone–siltstone/mudstone) from two distinctive outcrops of Permo‐Carboniferous glacial rhythmites in the Itararé Group (Paraná Basin, Brazil).

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.

New Paleointensity Data Suggest Possible Phanerozoic‐Type Paleomagnetic Variations in the Precambrian

Geochemistry, Geophysics, Geosystems, 2021
The state of the geomagnetic field throughout the Precambrian era is largely unknown. Approximately 8% of global paleointensity records account for ∼4 billion years of Earth history.

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 ...

Paleomagnetic Dating of Sediments in Caves Opened During Highway Construction Near Kozina, Slovenia

Acta Carsologica, 2016
V članku poročamo o paleomagnetizmu jamskih sedimentov v JZ Sloveniji. Vzorci so bili vzeti iz dveh denudiranih jam, ki sta se v letu 1999 odprli ob gradnji avtoceste pri Kozini. Vsi vzorci so pokazali normalno magnetno polariteto. Imeli so dobro vzorčno

Quantifying Inclination Shallowing and Representing Flattening Uncertainty in Sedimentary Paleomagnetic Poles

Geochemistry, Geophysics, Geosystems, 2022
Inclination is the angle of a magnetization vector from horizontal. Clastic sedimentary rocks often experience inclination shallowing whereby syn‐ to post‐depositional processes result in flattened detrital remanent magnetizations relative to local ...
