Plate tectonics and convection in the Earth's mantle: toward a numerical simulation [PDF]

open access: yes, 2000
Plate tectonics is a kinematic description of Earth that treats the outer shell of its mantle as a number of plates or rigid spherical caps that move with respect to each other (see the “Plate tectonics” sidebar).

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

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 ...

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.

The Theory of Plate Tectonics [PDF]

open access: yes
This is a brief overview of the Theory of Plate Tectonics. According to the theory, the Earth's surface layer, or lithosphere, consists of seven large and 18 smaller plates that move and interact in various ways.

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 ...

Accretionary Tectonics of the North American Cordillera [PDF]

open access: yes, 1983
Continental geology stands on the threshold of a change that is likely to be as fundamental as plate-tectonic theory was for marine geology. Ongoing seismic-reflection investigations into the deep crustal structure of North America are verifying that ...

Indonesian inquiry: A narrative of biocultural teaching on Sulawesi Utara

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Using phenomenology, narrative inquiry and autoethnographic approaches, this study analyses a program of faculty development conducted alongside the delivery of an international field school. Through this study, we explore the value and benefits of inter‐cultural field programming and how these might serve to complement or to redress ...
