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. On Earth, plate tectonics has been proposed as a necessary condition for life.

The Evolution of the Continental Crust and the Onset of Plate Tectonics
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.

Initiation of plate tectonics from post‐magma ocean thermochemical convection [PDF]
Journal of Geophysical Research: Solid Earth, 2014 Leading theories for the presence of plate tectonics on Earth typically appeal to the role of present day conditions in promoting rheological weakening of the lithosphere. However, it is unknown whether the conditions of the early Earth were favorable for plate tectonics, or any form of subduction, and thus how subduction begins is unclear.

Plate Tectonics and the Archean Earth
Annual Review of Earth and Planetary Sciences, 2020 If we accept that a critical condition for plate tectonics is the creation and maintenance of a global network of narrow boundaries separating multiple plates, then to argue for plate tectonics during the Archean requires more than a local record of ...

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

Geosciences, 2023 The Paleozoic volcano-sedimentary rocks within the structural basement of the horst-and-graben system of the Catalan Coastal Ranges (CCR) are composed of black shale, volcaniclastic sediments, lava flows, sills and lithocrystalloclastic tuffs.

Archean eclogite-facies oceanic crust indicates modern-style plate tectonics
Proceedings of the National Academy of Sciences of the United States of America, 2022 Significance The onset time of plate tectonics is highly debated in the Earth sciences. A key indicator of modern-style plate tectonics, with deep subduction of oceanic plates, is the presence of eclogite (oceanic crust metamorphosed at high-pressure and

Journal of Comparative Neurology, Volume 531, Issue 3, Page 366-389, February 2023., 2023 Photomicrograph of orexinergic neurons forming the main orexinergic neuronal cluster in the hypothalamus of a Southeast African cheetah. While showing the standard features of the orexinergic system, the Southeast African cheetah, along with an Asiatic and an African lion, also exhibits specializations in the organization of this system.
