Southward expanding plate coupling due to variation in sediment subduction as a cause of Andean growth

open access: yesNature Communications, 2021
Climate and tectonics control the distribution of trench sediments which in turn exerts a strong influence on tectonics by controlling the coupling strength of plate interface. This process could have caused the southward growth of the Andes.

Effects of Composite Rheology on Plate‐Like Behavior in Global‐Scale Mantle Convection

open access: yesGeophysical Research Letters, 2023
Earth's upper mantle rheology controls lithosphere‐asthenosphere coupling and thus surface tectonics. Rock deformation experiments and seismic anisotropy measurements indicate that composite rheology (co‐existing diffusion and dislocation creep) occurs ...

Tectonic Archaeology as a Foundation for Geoarchaeology

open access: yesLand, 2021
This article proposes a new subdiscipline, Tectonic Archaeology, based on the efforts of Japanese archaeologists to deal with the effects of earthquakes, volcanic tephra cover, and tsunami on archaeological sites.

Deconstructing Tectonics: Ten Animated Explorations

open access: yesEarth and Space Science, 2020
The configuration of continents and oceans of our tectonically active planet is ever changing. Using new, high‐resolution paleogeographic base maps, we created a set of animations that examine key elements of plate tectonics.

A Tectonic Manifesto

open access: yesPerspectives of Earth and Space Scientists, 2023
Tectonics is the scientific discipline that studies the relationship between planetary convection and surface deformation and magmatism. In recent years global tectonic regimes and planetary evolution have become foci of astronomical and planetological ...

Plate tectonics and Russian geology

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2017
A wide distribution of the US hypothesis of plate tectonics in the geological enterprises, in the geological universities of the country and in the editorial of the geological journals has been considered. This hypothesis was created 50 years ago and was

Differentiating induced versus spontaneous subduction initiation using thermomechanical models and metamorphic soles

open access: yesNature Communications, 2021
The mechanism of subduction initiation is a key to modern plate tectonics. Here, using numerical modeling and geological observations, the authors find that the majority of active and paleo subduction zones with metamorphic soles likely formed during ...

Regarding the article by V.V. Gordienko «On the nature of the Earth’s magnetic field»

open access: yesГеофизический журнал
V.V. Gordienko's article "On the Nature of the Earth's Magnetic Field" is aimed at criticizing plate tectonics. The author argues that paleomagnetic data are used to justify the mechanisms of lithospheric plate movement without sufficient grounds ...

Hadean/Eoarchean tectonics and mantle mixing induced by impacts: a three-dimensional study

open access: yesProgress in Earth and Planetary Science, 2022
The timing of the onset of plate tectonics on Earth remains a topic of strong debate, as does the tectonic mode that preceded modern plate tectonics.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...
