Problems With Net Tectonic Rotation for Dikes and Suggestions for Alternative Approaches

Geochemistry, Geophysics, Geosystems, 2021
The net tectonic rotation method is an alternative to paleomagnetic tilt corrections. The method was originally developed for sedimentary rocks and lavas, which have paleohorizontal indicators, but was later adapted for dikes by assuming that dikes ...

Paleomagnetism in Lake Pannon: Problems, Pitfalls, and Progress in Using Iron Sulfides for Magnetostratigraphy [PDF]

, 2018
Dating of upper Miocene sediments of the Pannonian Basin (Hungary) has proven difficult due to the endemic nature of biota, scarcity of reliable radio isotopic data, and generally inconsistent magnetostratigraphic results.

Micromagnetic Tomography for paleomagnetism and rock-magnetism [PDF]

, 2021
Our understanding of the past behavior of the geomagnetic field arises from magnetic signals stored in geological materials, e.g. (volcanic) rocks. Bulk rock samples, however, often contain magnetic grains that differ in chemistry, size and shape; some ...

Brunhes Paleomagnetic Directions and Paleointensities From Northern Hainan Island

Geochemistry, Geophysics, Geosystems
Paleomagnetic studies typically assume that the long‐term, time‐averaged geomagnetic field behaves as a geocentric axial dipole (GAD). While paleodirectional data over the past five million years generally agree with GAD predictions, mid‐to‐low latitude ...

ADRIA AS PROMONTORY OF AFRICA AND ITS CONCEPTUAL ROLE IN THE TETHYS TWIST AND PANGEA B TO PANGEA A TRANSFORMATION IN THE PERMIAN

Rivista Italiana di Paleontologia e Stratigrafia, 2018
It has been almost 60 years since the first results from the Early Permian Bolzano Quartz Porphyries from the Trento Plateau of northern Italy (Southern Alps) showed paleomagnetic inclinations steeper than inclinations from broadly coeval units from ...

Quaternions for rotations in paleomagnetism

Mathematical Geosciences, 2022
Abstract A variety of rotation operations are needed in paleomagnetism. These include transformations to the geographic coordinate system, tilt correction, finding virtual geomagnetic poles, and drawing demagnetization paths. Different methods have been used for each rotation operation - graphical manipulations on a stereonet, matrix ...

Ecological and Hydrological Modulation of Land Surface Temperature in the East Asian Monsoon Margin During Pliocene‐Pleistocene Global Cooling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The response of terrestrial climate to future warming remains debated. The Pliocene, with CO2 levels similar to today, is an important analog for the future. The East Asian monsoon marginal region is one of the most climate sensitive regions on Earth. Based on contemporaneous aeolian sediments and aquatic‐influenced alluvial sediments from the

Low Geomagnetic Field Intensity in Southern China 6,000 Years Ago

Geophysical Research Letters
The West Pacific Anomaly (WPA), a low geomagnetic field anomaly observed in the 16th to 18th centuries, represents a recently recognized and complex feature of Earth's magnetic field.

A Relative Paleointensity (RPI)-Calibrated Age Model for the Corinth Syn-rift Sequence at IODP Hole M0079A (Gulf of Corinth, Greece)

Frontiers in Earth Science, 2022
The Corinth basin (Greece) is a young continental rift that recorded cyclic basin paleoenvironment variations (i.e., marine to lacustrine) caused by glacio-eustatic sea level fluctuations during its initial connection to the global oceans.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.
