The Devonian has long been a problematic period for paleomagnetism. Devonian
paleomagnetic data are generally difficult to interpret and have complex partial or full …

Our understanding of geomagnetic field intensity prior to the era of direct instrumental
measurements relies on paleointensity analysis of rocks and archaeological materials that …

Obtaining estimates of Earth's magnetic field strength in deep time is complicated by
nonideal rock magnetic behavior in many igneous rocks. In this study, we target anorthosite …

The “new core paradox” suggests that the persistence of the geomagnetic field over nearly
all of Earth history is in conflict with the core being highly thermally conductive, which makes …

Paleointensity data can yield insight on the state of the geodynamo, providing constraints on
deep Earth events and enabling analysis of long-term trends in the paleomagnetic field. The …

The initiation of mobile-lid plate tectonics on Earth represented a critical transition towards a
more familiar world in terms of surface temperature stabilization, biogeochemical cycling …

The current morphology of Earth's time-averaged magnetic field can be approximated to a
geocentric axial dipole (GAD), but whether such an approximation remains valid in deep …

Single silicate crystals hosting tiny magnetic inclusions are remarkable targets to study the
paleointensities of the Earth and extraterrestrial samples. Since the pioneering work done in …

Abstract The South Atlantic Anomaly (SAA) is an area of geomagnetic weakness that
represents the most significant anomaly in the present‐day field. Notwithstanding anomalies …

Understanding the evolution of Earth's magnetic field can provide insights into core
processes and can constrain plate tectonics and atmospheric shielding. The absolute …
