Paleomagnetic Constraint of the Brunhes Age Sedimentary Record From Lake Junín, Peru
Frontiers in Earth Science, 2020 Normalized remanence, a proxy for relative geomagnetic paleointensity, along with radiocarbon and U-Th age constraints, facilitates the generation of a well-constrained chronology for sediments recovered during International Continental Scientific ...

Application of the pseudo-Thellier technique to a paleomagnetic record from lake El Trébol (Patagonia, Argentina) [PDF]
Geofísica Internacional, 2008 The pseudo-Thellier technique was applied to obtain relative paleointensity determinations using a sediment core from Lake El Trébol (Patagonia, Argentina).

Geochemistry, Geophysics, Geosystems, 2014 Eruptive timing in mid‐ocean ridge systems is relatively poorly constrained, despite being an important variable in our understanding of many mid‐ocean ridge processes, including volcanic construction; magma recharge, flux, and storage; and the stability

Holocene Paleointensity of the Island of Hawai `i From Glassy Volcanics
Geochemistry, Geophysics, Geosystems, 2018 This study presents new high‐quality paleointensity records and 14C radiocarbon age determinations from the Island of Hawai `i during the Holocene. Previous studies on Hawai `i use experimental methods and statistical selection criteria that may produce ...

Relative paleointensity stack during the last 250 kyr in the northwest Pacific [PDF]
Journal of Geophysical Research: Solid Earth, 2007 We have conducted a paleomagnetic study of 10 sediment cores recovered from the northwest Pacific. The purpose is to establish a regional paleointensity stack during the last 250 kyrs (NOPAPIS‐250) for global coverage of paleointensity data as well as a regional reference for paleointensity‐assisted stratigraphy.

Progress in Earth and Planetary Science, 2020 We present a novel paleomagnetic record for the lower Matuyama chronozone, which includes the Réunion subchronozone and the lower Olduvai polarity reversal, from a continuous section of a 168-m-thick on-land marine succession in the southernmost part of ...

Saw-toothed pattern of relative paleointensity records and cumulative viscous remanence [PDF]
Earth and Planetary Science Letters, 1996 Several studies of relative paleointensity data derived from marine sediments spanning the last 4 Myr display an asymmetrical “saw-toothed” pattern. Polarity reversals of the geomagnetic field are associated with low points in paleofield intensity, preceded by a long-term progressive decay of the field and followed by a rapid post-transitional recovery

Relative paleointensity (RPI) and age control in Quaternary sediment drifts off the Antarctic Peninsula [PDF]
Quaternary Science Reviews, 2019 Lack of foraminiferal carbonate in marine sediments deposited at high latitudes results in traditional oxygen isotope stratigraphy not playing a central role in Quaternary age control for a large portion of the globe. This limitation has affected the interpretation of Quaternary sediment drifts off the Antarctic Peninsula in a region critical for ...
