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 ...

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 ...

Geomorphological processes on terrestrial planetary surfaces [PDF]

, 1980
This review deals with features and processes on planetary surfaces, first by examining the impact of photographic explorations of Moon, Mars, and Mercury on studies of surface processes on our own planet, and second by treating matters related to ...

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 ...

Paleomagnetism

Eos, Transactions American Geophysical Union, 1989
The Third Annual Northeast Paleomagnetic Workshop was held September 23 at the University of Massachusetts, Amherst; Laurie Brown of the university's geology department was the organizer. On September 22, Sue Halgedahl of Lamont Doherty Geological Observatory, Palisades, N.Y., gave a lecture on magnetic domain structure and its relationship to ...

Paleomagnetism of the Devonian Onondaga Limestone Revisited [PDF]

, 1979
Ninety-six oriented samples were collected from 13 sites in the Onondaga limestone of New York for paleomagnetic study, including rock magnetism and magnetic susceptibility anisotropy.

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.

Silurian-Permian palaeocontinental reconstructions and circum-Atlantic tectonics [PDF]

, 1988
On the basis of the palaeomagnetic record, supplemented by constraints provided by faunal and tectonic information, reconstructions involving Laurentia, Baltica, Gondwana and numerous continent-like fragments and terranes within the circum-Atlantic ...

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.
