    A new cache of Eoarchaean detrital zircons from the Singhbhum craton, eastern India and constraints on early Earth geodynamics by Bulusu Sreenivas, Sukanta Dey, Y.J. Bhaskar Rao, T. Vijaya Kumar, E.V.S.S.K. Babu, Ian S. Williams

    Published 2019-07-01
    “…We observe a prominent shift in Hf isotope compositions at ∼3.6–3.5 Ga towards super-chondritic values, which signify an increased role for depleted mantle and the relevance of plate tectonics. The Paleo-, Mesoarchean zircon Hf isotopic record in the craton indicates crust generation involving the role of both depleted and enriched mantle sources. …”

    Inference and machine learning across the spatial scales in geophysics by Szenicer, A

    Published 2021
    “…This discount is crucial to enable us to image the interior of the Earth at higher resolutions, which is necessary to unlock the answers to some of the biggest questions in Earth science, e.g. related to the mechanisms of mantle convection and plate tectonics. Finally, I introduce how, with my teammates, we developed a deep learning replacement to a now defunct Sun-monitoring spectrograph onboard a NASA satellite. …”

    Emergence of a habitable planet by Zahnle, K, Arndt, N, Cockell, C, Halliday, A, Nisbet, E, Selsis, F, Sleep, N

    Published 2007
    “…Moreover hundreds or thousands of asteroid impacts would have been big enough to melt the ice triggering brief impact summers. We suggest that plate tectonics as it works now was inadequate to handle typical Hadean heat flows of 0.2-0.5 W/m 2. …”

    Early Neoarchean geodynamic regime in the North China Craton: constraints from 2.7 Ga granitoids in the southern Jilin terrane by Liu, J, Zhang, H, Palin, RM, Liu, Z, Zhang, J, Cheng, C, Liu, X, Zhao, C

    Published 2024
    “…Combined with previous studies, we suggest that the North China Craton underwent significant crustal growth during the early Neoarchean, which was likely attributed to the synergistic effects of waning mantle plume activity and the coeval onset of plate tectonics.</p>…”

    Mesoarchean (ultra)-high temperature and high-pressure metamorphism along a microblock suture: Evidence from Earth's oldest khondalites in southern India by Yu, B, Santosh, M, Amaldev, T, Palin, RM

    Published 2020
    “…We correlate the high P–T metamorphism with the subduction-collision history between the northern margin of the Mercara block and the Western Dharwar Craton during the Mesoarchean, which indicates that plate tectonics had been established on Earth by at least ca. 3.1 Ga, in agreement with many independent lines of evidence. …”

    Seamount subduction and accretion in West Junggar, NW China: A review by Gaoxue Yang, Yongjun Li, Zhao Zhu, Hai Li, Lili Tong, Rong Zeng

    Published 2024-05-01
    “…The subducting and accreting seamounts in West Junggar are mainly involved in deformation of the overriding plate, magmatism of the volcanic arc and plate tectonics. Particularly, seamounts/oceanic plateaus accretion probably induced subduction initiation in West Junggar, namely subduction polarity-reversal and/or subduction transference. …”

    Atmospheric carbon dioxide and the long-term control of the Earth&apos;s climate by J. H. Carver, I. M. Vardavas

    “…During Mega-climate 2, evolutionary biological processes increased the surface weatherability in incremental steps and plate tectonics modulated the CO&lt;sub&gt;2&lt;/sub&gt; outgassing rate with an estimated period of 150 Myear (approximately one-half the period for the formation and breakup of super continents). …”

    δ18O and SST signal decomposition and dynamic of the Pliocene-Pleistocene climate system: new insights on orbital nonlinear behavior vs. long-term trend by Paolo Viaggi

    Published 2018-12-01
    “…The global δ18O, the tropical SST, and the global ΔSST trend components, all explaining ~ 76% of the Plio-Pleistocene variance and significantly modifying the mean climate state, appear to be related to the long-term pCO2 proxies, supposedly controlled by plate tectonics through the global carbon cycle (CO2 outgassing, explosive volcanism, orography and erosion, paleogeography, oceanic paleocirculation, and ocean fertilization). …”

    The dominant driving force for supercontinent breakup: Plume push or subduction retreat? by Nan Zhang, Zhuo Dang, Chuan Huang, Zheng-Xiang Li

    Published 2018-07-01
    “…Understanding the dominant force responsible for supercontinent breakup is crucial for establishing Earth's geodynamic evolution that includes supercontinent cycles and plate tectonics. Conventionally, two forces have been considered: the push by mantle plumes from the sub-continental mantle which is called the active force for breakup, and the dragging force from oceanic subduction retreat which is called the passive force for breakup. …”

    Published 2013-01-01
    “…The first coincided with the Lomagundi-Jatuli isotopic event and led to prolonged orogenesis accompanied by continental flooding and reconfiguration of the crust on the Earth's surface; the second led to continental break-up and instigated the comprehensive Plate Tectonics that has characterised Phanerozoic times. …”

    Toward a New Theory of Earth Crustal Displacement by Mark Carlotto

    Published 2022-05-01
    “…We contrast the first part of his theory with plate tectonics and true polar wander and propose a new mechanism that is triggered by short-term reversals of the geomagnetic field that “unlock” the crust from the mantle, driven by earth–moon–sun tidal forces, the same forces that move earth’s oceans. …”

    ADRIA AS PROMONTORY OF AFRICA AND ITS CONCEPTUAL ROLE IN THE TETHYS TWIST AND PANGEA B TO PANGEA A TRANSFORMATION IN THE PERMIAN by GIOVANNI MUTTONI, DENNIS V. KENT

    Published 2018-12-01
    “…This shear or transformation was initially thought to occur as a continuum over the course of the Mesozoic–Cenozoic (the so-called ‘Tethys Twist’) but soon afterwards when plate tectonics came into play and limited the younger extent, as a discrete event during the post-Triassic, Triassic or most probably – as in the latest and preferred reconstructions – the Permian between a configuration of Pangea termed B – with the northwestern margin of Africa against southern Europe – to a configuration termed Pangea A-2, with the northwestern margin of Africa against eastern North America, that is more proximal in shape to the classic Pangea A-1 that started fragmenting in the Jurassic with the opening of the Atlantic Ocean. …”
