High resolution paleosecular variations recorded in Lake Pleshcheevo sediments (Yaroslavl region, Russia)

2020
<p>In this paper we present the results of paleomagnetic investigations of the Lake Pleshcheevo sediments (Yaroslavl region, Russia). Sediments of modern lakes are a unique record's archive changes of environment, climate, geomagnetic field over the past millennia. From lake were selected 4 cores up to 6.3 meters.

Evolving core conditions ca. 2 billion years ago detected by paleosecular variation

Physics of the Earth and Planetary Interiors, 2011
Abstract 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 collected from Proterozoic and Neoarchean rocks.

Paleosecular variations 0–19,000 years recorded by sediments from Escondido Lake (Argentina)

Physics of the Earth and Planetary Interiors, 2002
Abstract Paleomagnetic and sedimentological studies carried out on four cores, about 11 m long, from the bottom sediments of Escondido Lake (southwestern Argentina) are described. This lake is geologically related to the set of lakes of glacial origin located in western Patagonia.

Archaeo‐ and paleosecular variation, and long‐term asymmetries of the geomagnetic field

Reviews of Geophysics, 1983
This report summarizes progress made during the last four years in (i) obtaining records of the geomagnetic secular variation using paleomagnetic techniques, (ii) analysis and modelling of the secular variation, and (iii) the study of asymmetries in the time‐averaged field: seen both as departures from the geocentric axial dipole model, and as ...

Comments on ‘A new method to determine paleosecular variation’ by D. Vandamme

Physics of the Earth and Planetary Interiors, 1997
The method developed by Vandamme (1994, Phys. Earth Planet. Inter., 85: 131–142) for the selection of the virtual geomagnetic pole (VGP) data set in terms of an optimum cutoff angle derived from analyses of synthetic VGP populations is applied to three Brunhes VGP data sets from central Mexico.
