Linearity of natural versus laboratory-imparted remanence demagnetization diagram and reliability of relative paleointensity estimation

Earth, Planets and Space
Information on geomagnetic field intensity in the past is essential for understanding the behavior and mechanism of the geodynamo. A fundamental unresolved problem of relative paleointensity (RPI) estimations from marine sediments is that changes in the ...

Relative paleointensity (RPI) of the Earth's magnetic field of sediment core PS69/899-2

Relative paleointensity (RPI) of the Earth's magnetic field from sediment cores PS69/899-2, located in the Indian sector of the Southern Ocean, covering the past 150,000 years, based on the age model described in Fripiat et al.

Geomagnetic relative paleointensity and direction during the last 40,000 years obtained from a sediment core in the Nankai Trough

Earth, Planets and Space
Construction of regional geomagnetic secular variation curves for the last several tens of thousands of years is important for understanding the behavior of non-dipole fields and applications to geochronology.

Cooling Following the Magnetic Field Weakening During the Matuyama–Brunhes Transition Recorded by Paks Loess, Hungary

Quaternary
Detailed paleomagnetic and rock magnetic investigations of the Paks loess (Hungary) were conducted to determine the stratigraphic position of the Matuyama–Brunhes Transition (MBT) and to attempt to reveal the sign of any possible influences of ...

A geomagnetic paleointensity stack between 0.8 and 3.0 Ma from equatorial Pacific sediment cores

, 2005
We have conducted a paleomagnetic study of six sediment cores taken from the equatorial Pacific, three from the West Caroline Basin and three from the Manihiki Plateau, in order to make a relative paleointensity stack during the Matuyama and late Gauss ...

Reconstruction of high-resolution paleomagnetic variations in the middle Gauss chronozone, including the upper and lower boundaries of the Mammoth reversed subchronozone

Earth, Planets and Space
In this study, we provide paleomagnetic records, including the upper and lower boundaries of the Mammoth reversed subchronozone, reconstructed from a continuous outcrop of the upper marine Pliocene in the southernmost part of the Boso Peninsula, which is

Umbria-Marche Basin, Central Italy: A Reference Section for the Aptian-Albian Interval at Low Latitudes

Scientific Drilling, 2012
Within the Cretaceous Period, the Aptian-Albian interval (125–99.6 Ma, Ogg et al., 2008) was a critical time on a global scale. This is evident from 1) changes in the nature of the ocean-climate system brought about by increased ocean crust production ...

Relative geomagnetic paleointensity from the Jaramillo Subchron to the Matuyama/Brunhes boundary as recorded in a Mediterranean piston core

, 2002
Piston core LC07, located west of the Sicily Strait in the Mediterranean Sea, unambiguously records the Matuyama/ Brunhes (M/B) and the upper Jaramillo polarity reversals, with similar average sediment accumulation rates (SARs) for the Brunhes Chron (2.
