Comparing Paleointensity Recording Efficiencies of Detrital and Biogenic Magnetite by Deposition Experiments With Synthetic Sediments

open access: yesGeochemistry, Geophysics, Geosystems
Marine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time.

Limitations in correlation of regional relative geomagnetic paleointensity [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2006
Time domain correlations of common features among relative paleointensity records from sedimentary cores are invaluable to paleomagnetism and paleoclimatology. Sediments with high accumulation rates might now provide millennial scale correlations of temporal variations in the geomagnetic dipole moment.

High-Fidelity Archeointensity Results for the Late Neolithic Period From Central China [PDF]

open access: yes, 2020
Archeomagnetism focuses on exploring high-resolution variations of the geomagnetic field over hundreds to thousands of years. In this study, we carried out a comprehensive study of chronology, absolute and relative paleointensity on a late Neolithic site

Dating North Pacific Abyssal Sediments by Geomagnetic Paleointensity: Implications of Magnetization Carriers, Plio-Pleistocene Climate Change, and Benthic Redox Conditions

open access: yesFrontiers in Earth Science, 2021
Non-carbonaceous abyssal fine-grained sediments cover vast parts of the North Pacific’s deep oceanic basins and gain increasing interests as glacial carbon traps.

Relative Paleointensity Record of Integrated Ocean Drilling Program Site U1396 in the Caribbean Sea: Geomagnetic and Chronostratigraphic Observations in the Pliocene

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Continuous sedimentary records of paleomagnetic directional variability and relative paleointensity (RPI) provide valuable information on the evolution of the geodynamo while also facilitating stratigraphic correlation and age control.

Further evidence for early lunar magnetism from troctolite 76535 [PDF]

open access: yes, 2017
The earliest history of the lunar dynamo is largely unknown and has important implications for the thermal state of the Moon and the physics of dynamo generation.

Relative paleointensity in sediments: A Pseudo‐Thellier Approach

open access: yesGeophysical Research Letters, 1995
We present a method for normalizing sedimentary records for estimating relative paleointensity of the geomagnetic field, similar to that successfully used to obtain absolute paleointensity from thermally blocked remanences. It has the advantages that it is more effective in removing unwanted viscous remanence, thereby improving agreement among various ...

A comparison of different techniques for relative paleointensity

open access: yesGeophysical Research Letters, 1998
Parallel relative paleointensity records that are supposed to display the same geomagnetic variations often show discrepancies. We compared various techniques of normalization with different parameters involving alternating fields (a.f.) and thermal demagnetization of sediment samples spanning the same period from the Indian and the Pacific oceans.

A Relative Paleointensity (RPI)-Calibrated Age Model for the Corinth Syn-rift Sequence at IODP Hole M0079A (Gulf of Corinth, Greece)

open access: yesFrontiers in Earth Science, 2022
The Corinth basin (Greece) is a young continental rift that recorded cyclic basin paleoenvironment variations (i.e., marine to lacustrine) caused by glacio-eustatic sea level fluctuations during its initial connection to the global oceans.

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

open access: yesGeosystems 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 ...
