Sedimentary environment, lithostratigraphy and dating of sediment sequences from Arctic lakes Revvatnet and Svartvatnet in Hornsund, Svalbard

Polish Polar Research, 2016
The sedimentary environment, sediment characteristics and age-depth models of sediment sequences from Arctic lakes Revvatnet and Svartvatnet, located near the Polish Polar Station in Hornsund, southern Svalbard (77°N), were studied with a view to ...

Late Mesoproterozoic Rapid True Polar Wander Recorded in the Jingeryu Formation, North China Craton

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Disentangling short‐duration (≤10 Ma) true polar wander (TPW) events in the Precambrian presents a significant challenge, necessitating the acquisition of high‐resolution and ‐quality paleomagnetic data and well‐determined age relations. This study reports new paleomagnetic results from carbonate sequences of the Jingeryu Formation in the ...

Improving the reconstruction of Holocene geomagnetic paleosecular variation in the Antarctic region

Physics of the Earth and Planetary Interiors
We present new paleomagnetic data from the ANTA02-AV43 core collected in the Ross Sea (Antarctica), spanning the last 10 ka. Results document a relative paleointensity (RPI) record that closely matches predictions from global geomagnetic models and from previously published records from nearby peri-Antarctic margins, including the Ross Sea and Wilkes ...

Termination of Laurentia's Rapid Plate Motion at the Start of the Grenvillian Orogeny

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Late Mesoproterozoic to Neoproterozoic sedimentary sequences within the Lake Superior region preserve critical paleogeographic records of the position of Laurentia spanning from the end of Midcontinent Rift extension through to the end of the Grenvillian Orogeny.

Evolving Core Conditions ca. 2 Billion Years Ago Detected by Paleosecular Variation

, 2011
Paleomagnetic data provide one of the few probes available to interrogate early evolution of the core. Here we apply this probe by examining the latitudinal dependence of paleosecular variation (PSV) data derived from high-quality paleomagnetic data ...

Detecting and correcting for paleomagnetic inclination shallowing of sedimentary rocks: A review

Frontiers in Earth Science, 2016
Magnetic anisotropy and the elongation/inclination (E-I) approaches have been increasingly employed as two important means for detecting and correcting the paleomagnetic inclination shallowing in sedimentary rocks that was first recognized sixty years ...

Paleomagnetic results from Costa Rica, Jan Mayen and Spitsbergen : an investigation of paleosecular variation over the last 10 Ma [PDF]

, 2010
Paleosecular variation (PSV) models require high-quality, globally distributed paleomagnetic data sets in order to accurately predict observed geomagnetic field behavior.
