Determining Magnetic Field Intensity and Direction From the Anisotropy of Magnetic Remanence in Sediments

Geochemistry, Geophysics, Geosystems
Anisotropy of magnetic remanence (AMR) holds promise for quantifying relative paleointensity values from sedimentary rocks. A proof of concept was established for applied fields that exceeded the intensity of the geomagnetic field.

Eruptive timing and 200 year episodicity at 92°W on the hot spot‐influenced Galapagos Spreading Center derived from geomagnetic paleointensity

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

A stacked record of relative paleointensity for the past 500 ka in the western equatorial Indian Ocean

, 2023
<p>High-quality relative paleointensity (RPI) is important for the study of Earth Interior and sediments dating. Many existing high-resolution RPI curves have been obtained from the North Atlantic and Pacific Ocean.

Paleoclimate evolution of the North Pacific Ocean during the late Quaternary: Progress and challenges

Geosystems and Geoenvironment, 2023
High- and low-latitude climatic processes in the North Pacific Ocean are important components of the global climate system. For example, the interplay among North Pacific atmospheric circulation, ocean circulation, and biological productivity affects ...

A paleomagnetic record in loess–paleosol sequences since late Pleistocene in the arid Central Asia

Earth, Planets and Space, 2018
Geomagnetic excursions during Brunhes epoch have been brought to the forefront topic in paleomagnetic study, as they provide key information about Earth’s interior dynamics and could serve as another tool for stratigraphic correlation among different ...

Natural remanent magnetization acquisition in bioturbated sediment: General theory and implications for relative paleointensity reconstructions

Geochemistry, Geophysics, Geosystems, 2015
We present a general theory for the acquisition of natural remanent magnetizations (NRM) in sediment under the influence of (a) magnetic torques, (b) randomizing torques, and (c) torques resulting from interaction forces.

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 ...

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 ...
