Nature 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 ...

Geophysical 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.

Photoferrotrophic Bacteria Initiated Plate Tectonics in the Neoarchean
Geophysical 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 ...

Nature 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
Land, 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
Geophysical 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]
E3S 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 ...

Inevitability of Plate Tectonics on Super-Earths [PDF]
, 2007 The recent discovery of super-Earths (masses less or equal to 10 earth-masses) has initiated a discussion about conditions for habitable worlds. Among these is the mode of convection, which influences a planet's thermal evolution and surface conditions ...

The Ability of Significant Tidal Stress to Initiate Plate Tectonics [PDF]
, 2019 Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth's climate, and may be better understood by identifying rocky planets outside our solar system with tectonic activity.
