Reviewing subduction initiation and the origin of plate tectonics: What do we learn from present-day Earth?

open access: yesEarth and Planetary Physics, 2021
The theory of plate tectonics came together in the 1960s, achieving wide acceptance after 1968. Since then it has been the most successful framework for investigations of Earth’s evolution. Subduction of the oceanic lithosphere, as the engine that drives

Alpine-style nappes thrust over ancient North China continental margin demonstrate large Archean horizontal plate motions

open access: yesNature Communications, 2021
How far back in time plate tectonics operated on Earth is debated because of a paucity of geological evidence for horizontal plate motions. Here the authors show that plates moved laterally by >3500 kilometres 2.7–2.5 billion years ago, demonstrating ...

Photoferrotrophic Bacteria Initiated Plate Tectonics in the Neoarchean

open access: yesGeophysical Research Letters, 2023
Plate tectonics distinguishes Earth from the other terrestrial planets but its initiation mechanism and onset time are debated. We propose plate tectonics was initiated by the deposition of magnetite‐rich banded iron formations (BIFs) through ...

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.

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.

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 ...

Diagnosis of learning difficulties of plate tectonics concepts among secondary school students using: Focus group, nominal group, and questionnaire [PDF]

open access: yesE3S Web of Conferences, 2023
The teaching of geology or earth sciences occupies an important place in the life and earth sciences programs of the secondary cycle in Morocco. The theory of plate tectonics is the conceptual model that allows an understanding of most of the dynamic ...

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 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.

Trench-parallel ridge subduction controls upper-plate structure and shallow megathrust seismogenesis along the Jalisco-Colima margin, Mexico

open access: yesCommunications Earth & Environment, 2023
Trench-parallel ridges on the Rivera plate subducting beneath W Mexico, control upper-plate tectonics and elastic structure, and act as unstable asperities, enabling shallow megathrust seismogenesis, according to seismic imaging and tomographic modeling.
