“…They have led to numerous models involving interaction of subducted lithosphere, deep mantle convection, and return of old crustal material to be preserved within younger oceanic lithosphere (Robinson et al, 2015;González-Jiménez et al, 2017;Lian et al, 2020). We report the first unambiguous occurrence of an UHP mineral from an inclusion in chromite from a podiform chromitite block in a well-characterized Neoarchean ophiolitic mélange (Li et al, 2002;Kusky et al, 2016;2020;Wang et al, 2019;Ning et al, 2020;Huang et al, 2021). We interpret this result to relate to plate tectonic processes that must have operated before 2.5 Ga and is significant for characterizing plate tectonic processes on early Earth, constraining the minimum depths of subduction, and tracking the interaction of surface tectonic-and deep mantle convective-recycling processes through deep time.…”

“…Because of the higher heat production in the Archean (Korenaga, 2013;Herzberg et al, 2010) there has been much modeling and speculation that mantle temperatures may have been significantly higher, thus preventing subduction (c.f.van Hunen and Moyen, 2012), or may have been significantly different from the modern style of subduction (c.f. Zheng and Zhao, 2020;Kusky, 2020). However, Aulbach and Arndt (2019) have argued that mantle temperatures have not exceeded present values by more than 100°C over the past 3.0 Ga, and Agrusta et al (2018) use numerical modeling to suggest that warmer mantle temperatures set up conditions that enhanced deep subduction and facilitated recycling of volatiles to the deep mantle.…”

“…The metamorphic rock record provides strong evidence for sustained subduction for at least the last 700 million years (Brown et al, 2020;Brown and Johnson, 2018;Stern, 2005) with the prevalence of low-temperature eclogite and blueschist facies, and paired metamorphism. This record of cold-subduction is widespread in the Phanerozoic (Brown and Johnson, 2018), but the apparent absence of evidence for low geothermal gradients (T/P) in the greater part of the Proterozoic and during the Archaean (Brown et al, 2020;Brown and Johnson, 2018) has been argued as indicating that a different tectonic regime prevailed prior to the Neoproterozoic (Kusky, 2020;Stern, 2005). Exceptionally, late Palaeoproterozoic, partially retrogressed eclogite units have been reported (e.g.…”

“…Response to this rudimentary issue has been ventured via geochemical and numerical modelling [7,[17][18][19][20][21][22][23], as well as by auditing the cratonic outskirts engrossed by abiding mobile belts, which conserve a sustained history of supercontinent cycles. Accretionary orogeny (a subdomain of plate tectonics) has been envisaged as a key process in this scenario [14,21,24,25], which contribute substantially to cratonic growth through episodic augmentation of juvenile material [26][27][28]. Crustal-scale fault-shear zones are pivotal components in such belts, which help to stitch disparate terranes through protracted and/or punctuated tectonic cycles [29][30][31][32][33][34][35][36].…”
