The Evolution of the Continental Crust and the Onset of Plate Tectonics [PDF]
Frontiers in Earth Science, 2020 The Earth is the only known planet where plate tectonics is active, and different studies have concluded that plate tectonics commenced at times from the early Hadean to 700 Ma.

The evolution of plate tectonics [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2018 To understand how plate tectonics became Earth's dominant mode of convection, we need to address three related problems. (i) What was Earth's tectonic regime before the present episode of plate tectonics began? (ii) Given the preceding tectonic regime, how did plate tectonics become established?

The importance of continents, oceans and plate tectonics for the evolution of complex life: implications for finding extraterrestrial civilizations [PDF]
Scientific ReportsWithin the uncertainties of involved astronomical and biological parameters, the Drake Equation typically predicts that there should be many exoplanets in our galaxy hosting active, communicative civilizations (ACCs).

Anatomy of a post-subduction collision [PDF]
Nature CommunicationsThe spatiotemporal interplay of long-lasting post-orogenic deformations make continental collision zones among Earth’s most enigmatic systems. Here, we employ three-dimensional thermomechanical modeling to decode mantle dynamics of the Arabian-Eurasian ...

On the plate velocity scaling break [PDF]
Scientific ReportsThis research presents the discovery of a kink in the frequency-size distribution of plate angular velocities in different reference frames, a feature not predicted by current physical models of plate tectonics.

Earth 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

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 ...

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 ...
