“…The AOA lineages with the first indication of being capable of ammonia oxidation diverged from other non-AOA lineages around1.16 Ga (94% CI: 1.93–0.88 Ga), coinciding with the main collisional events resulting in the formation of the Rodinia supercontinent which took place at ∼1.1 Ga (ca. 1.2–1.0 Ga) (divergence node #2) ( Martin et al 2020 ). A large increase of global subduction-induced arc-volcanism and thermal activity resulted from the amalgamation of Rodinia ( Liu et al 2017 ), potentially creating a long-term suitable macro-environment for the origin of thermophilic traits in AOA ancestors, which have been kept in the modern ThAOA group.…”

“…Among the supercontinents, Rodinia was characterized as having much more intense global subduction-induced arc-volcanism and thermal activity resulting from amalgamation ( Liu et al 2017 ). The amalgamation of Rodinia was a long-lived event but its core was formed around 1.1 Ga (1.2–1.0 Ga) ( Martin et al 2020 ). This coincides with the origination time of AOA at ∼1.16 Ga, suggesting it might have created conditions triggering the emergence of thermophilic traits in AOA and allowed them to gradually adapt and evolve into the new environments.…”

Primordial nitrification processes have been studied extensively using geochemical approaches, but the biological origination of nitrification remains unclear. Ammonia-oxidizing archaea (AOA) are widely distributed nitrifiers and implement the rate-limiting step in nitrification. They are hypothesized to have been important players in the global nitrogen cycle in Earth’s early history. We performed systematic phylogenomic and marker gene analyses to elucidate the diversification timeline of AOA evolution. Our results suggested that the AOA ancestor experienced terrestrial geothermal environments at ∼1,165 Ma (1,928-880 Ma), and gradually evolved into mesophilic soil at ∼652 Ma (767-554 Ma) before diversifying into marine settings at ∼509 Ma (629-412 Ma) and later into shallow and deep oceans, respectively. Corroborated by geochemical evidence and modeling, the timing of key diversification nodes can be linked to the global magmatism and glaciation associated with the assembly and breakup of the supercontinent Rodinia, and the later oxygenation of the deep ocean. Results of this integrated study shed light on the geological forces that may have shaped the evolutionary pathways of the AOA, which played an important role in the ancient global nitrogen cycle.

“…Notwithstanding this petrogenetic complexity, there is clear secular change and modulation of the supercontinent cycle, with a higher rate of production of strongly peraluminous granites and greater crustal reworking during the amalgamation of the Gondwana and Nuna megacontinents than during the assembly of Rodinia (Wang et al, 2021;Zhu et al, 2020). The difference was likely controlled by contrasting geodynamic configurations in which the assembly of Rodinia was dominated by young accretionary orogens on opposing margins prior to amalgamation in contrast to the suturing of the Gondwana and Nuna megacontinents where both old passive and young accretionary margins were involved (Martin et al, 2020;Spencer et al, 2013). are assigned to specific Proterozoic orogens (from Condie, 2021) and compared to the range of T/P values for Phanerozoic orogens .…”

Uniformitarianism-"the present is the key to the past"-limits our ability to fully understand the emergence and evolution of plate tectonics during the Precambrian (Stern & Gerya, 2021). Before the Proterozoic, the volume of preserved continental crust is too small to argue that localized evidence of short-lived subduction demonstrates the existence of a fragmented lithosphere and a linked network of boundaries, that is, a global plate tectonics mode, although this remains permissible (Brown et al., 2020;O'Neill et al., 2018). Whether plate tectonics emerged during or before the Archean relies mostly on geochemical arguments (Guo & Korenaga, 2020), which can sometimes be inconclusive and open to alternative interpretation (Brown et al., 2020;O'Neill et al., 2018). Notwithstanding, there is general agreement that plate tectonics has been operating on Earth since the end of the Archean. Also, geophysical evidence of subduction becomes widespread in the Paleoproterozoic (Wan et al., 2020) supporting the interpretation that a plate tectonics mode operated at least by the early Paleoproterozoic.Despite the broad consensus that plate tectonics was operational by the early Proterozoic, the style and continuity of plate tectonics during the remainder of the eon have proven to be controversial, with both a distinct Proterozoic style of plate tectonics or a period of single-lid tectonics in the Mesoproterozoic being proposed as alternatives to the null hypothesis of uniformitarianism (

“…The Grenville orogen sensu stricto, including the eastern margin of Laurentia and its immediate neighbors (e.g., Baltica and Amazonia; Martin et al, 2020), is largely characterized by intermediate-and high-T/P metamorphism, with only one low-T/P locality (Fig. 3C).…”

Since the Jurassic, there has been a clear spatiotemporal correlation between different types of metamorphism and active convergent plate margins. However, the extent to which this relationship extends into the past is poorly understood. We compared paleogeographic reconstructions and inferred plate kinematics with the age and thermobaric ratio (temperature/pressure [T/P]) of metamorphism over the past 2 b.y. The null hypothesis—that there is no spatiotemporal link between inferred plate margins and metamorphism—can be rejected. Low-T/P metamorphism is almost exclusively located near plate margins, whereas intermediate- and high-T/P metamorphism skews toward increasingly greater distances from these margins, consistent with three different tectonic settings: the subduction zone, the mountain belt, and the orogenic hinterland, respectively. However, paleogeographic reconstructions suggest that so-called “paired metamorphic belts” are rare and that high- and low-T/P localities more commonly occur along strike from each other. The observation that bimodal metamorphism is largely a function of distance from the trench and that end-member T/P types rarely occur in the same place can be explained if the style of orogenesis has evolved from hotter to colder, consistent with the abrupt emergence of low-T/P metamorphism in the Cryogenian. The widespread development of high-T/P rocks in orogenic hinterlands in the Proterozoic was followed by the production and efficient exhumation of low-T/P rocks in subduction channels in the Phanerozoic.
