On the biospheric effects of geomagnetic reversals. [PDF]

open access: yesNatl Sci Rev, 2023
This perspective argues an evolutionary effect of geomagnetic field reversals on life and highlights the urgency of multidisciplinary studies on the linkage between Earth's magnetic field and biosphere.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

REVERSALS IN THE 6-CELLS CONVECTION DRIVEN [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2015
We describe the large-scale model geodynamo, which based on indirect data of inhomogeneities in the density of the Earth’s core. Convection structure is associated with spherical harmonic Y24 , which defines the basic poloidal component of velocity ...

GEOMAGNETIC EXCURSION RECORD PRESERVED IN THE SPELEOTHEM FROM WESTERN CAUCASUS: FIRST DATA

open access: yesГеодинамика и тектонофизика, 2022
The study of the geomagnetic field evolution on minor timescales, in particular of such significant events as geomagnetic reversals and excursions, has acquired particular relevance nowadays due to the increased attention of mankind to the environment ...

Some new approaches to the study of the Earth's magnetic field reversals

open access: yesAnnals of Geophysics, 2003
Paleomagnetic studies clearly show that the polarity of the magnetic fi eld has been subject to reversals. It is generally assumed that polarity intervals are exponentially distributed.

A coupled core-mantle evolution: review and future prospects

open access: yesProgress in Earth and Planetary Science, 2020
In this review, I provide the current status and future prospects for the coupled core-mantle evolution and specifically summarize the constraints arising from geomagnetism and paleomagnetism on the long-term secular variations of the geomagnetic field ...
