Insights into pre-reversal paleosecular variation from stochastic models [PDF]
To provide insights on the paleosecular variation of the geomagnetic field and the mechanism of reversals, long time series of the dipolar magnetic moment are generated by two different stochastic models, known as the domino model and the inhomogeneous ...

Assessing the reliability of paleomagnetic datasets using the R package PmagDiR [PDF]
Paleomagnetism is the most important source of information for determining the position of tectonic plates in the geological past. Over the last few decades significant advancements have been made in improving the reliability of paleomagnetic data ...

Bayesian Inference of Local Paleosecular Variation From Sparse Paleomagnetic Data
Abstract We introduce a novel Bayesian method to construct local paleosecular variation (PSV) curves. By modeling the geomagnetic field as a Gaussian process, global models can be incorporated as informative prior distributions. Because we use Hamiltonian Monte‐Carlo methods, complex age distributions resulting for example from radiocarbon calibration ...

Brunhes Paleomagnetic Directions and Paleointensities From Northern Hainan Island
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 ...

An archaeomagnetic study of the Ishtar Gate, Babylon. [PDF]
Data from the marriage of paleomagnetism and archaeology (archaeomagnetism) are the backbone of attempts to create geomagnetic field models for ancient times. Paleointensity experimental design has been the focus of intensive efforts and the requirements

A Holocene Paleosecular Variation Record From the Northwestern Ross Sea, Antarctica
We present a mid‐to‐late Holocene record of relative paleosecular variation from the Ross Sea region of Antarctica. The 6,700‐year‐long record of inclination, declination, and relative paleointensity from a marine sediment core collected near Cape Adare ...

Paleosecular variation recorded by Quaternary lava flows from Guadeloupe Island. [PDF]
AbstractPaleomagnetic directional data were obtained from fourteen 0 to 2 Ma old lava flows at Basse-Terre Island (Guadeloupe, French West Indies). Five reversed polarity flows are consistent with their Matuyama age between 1.6–1.5 Ma and 875–790 ka while the ages of the other nine normal polarity units tie them to the Olduvai subchron and the Brunhes ...

A Feasibility Study of Microbialites as Paleomagnetic Recorders
Microbialites–layered, organosedimentary deposits–exist in the geologic record and extend back in deep time, including all estimated times of inner core nucleation.

The Cretaceous Normal Superchron (CNS) was first defined in the 1960s to explain the Cretaceous Quiet Zone in marine magnetic anomaly profiles, which includes no or fewer geomagnetic reversals.
