“…The best progress has been made in the Superior craton, where a series of precise U -Pb ages on mafic dyke swarms has been closely integrated with palaeomagnetic studies at the same localities, and with particular attention to baked-contact tests to demonstrate primary ages of magnetic remanence (e.g. Buchan et al 2007;Halls et al 2008). If a similar strategy is applied to other cratons then the solution of Kenorland or supercraton configurations will be much closer to realization.…”

The Palaeoproterozoic era was a time of profound change in Earth evolution and represented perhaps the first supercontinent cycle, from the amalgamation and dispersal of a possible Neoarchaean supercontinent to the formation of the 1.9-1.8 Ga supercontinent Nuna. This supercontinent cycle, although currently lacking in palaeogeographic detail, can in principle provide a contextual framework to investigate the relationships between deep-Earth and surface processes. In this article, we graphically summarize secular evolution from the Earth's core to its atmosphere, from the Neoarchaean to the Mesoproterozoic eras (specifically 3.0-1.2 Ga), to reveal intriguing temporal relationships across the various 'spheres' of the Earth system. At the broadest level our compilation confirms an important deep-Earth event at c. 2.7 Ga that is manifested in an abrupt increase in geodynamo palaeointensity, a peak in the global record of large igneous provinces, and a broad maximum in several mantle-depletion proxies. Temporal coincidence with juvenile continental crust production and orogenic gold, massive-sulphide and porphyry copper deposits, indicate enhanced mantle convection linked to a series of mantle plumes and/or slab avalanches. The subsequent stabilization of cratonic lithosphere, the possible development of Earth's first supercontinent and the emergence of the continents led to a changing surface environment in which voluminous banded iron-formations could accumulate on the continental margins and photosynthetic life could flourish. This in turn led to irreversible atmospheric oxidation at 2.4-2.3 Ga, extreme events in global carbon cycling, and the possible dissipation of a former methane greenhouse atmosphere that resulted in extensive Palaeoproterozoic ice ages. Following the great oxidation event, shallow marine sulphate levels rose, sediment-hosted and iron-oxide-rich metal deposits became abundant, and the transition to sulphide-stratified oceans provided the environment for early eukaryotic evolution. Recent advances in the geochronology of the global stratigraphic record have made these inferences possible. Frontiers for future research include more refined modelling of Earth's thermal and geodynamic evolution, palaeomagnetic studies of geodynamo intensity and continental motions, further geochronology and tectonic syntheses at regional levels, development of new isotopic systems to constrain geochemical cycles, and continued innovation in the search for records of early life in relation to changing palaeoenvironments.

“…The studies of temporal and spatial distribution and tectonic implication for the large igneous provinces (LIPs) in the world can provide good contribution to geological history, geodynamics and large-scale Cu-Ni sulfide deposits, even genetic links with mantle plume and mass extinction (Coffin and Eldholm, 1994;Chung and Jahn, 1995;Wignall, 2001;Zhou et al, 2002;Morgan et al, 2004;Dobretsov, 2005;Xu et al, 2001Xu et al, , 2007Halls et al, 2008;Pirajno et al, 2008), and therefore, it is very important to confirm and deeply study the newly discovered large igneous provinces in the world. During Permian-Triassic boundary and Permian period, the Siberian Traps and Emeishan large igneous province become two typical large igneous provinces.…”

Therefore, field contact relationships between Permian igneous rocks (basalt, basaltic andesite, olivine pyroxenite, syenite, bimodal dyke, and diabase swarm) and sedimentary rocks have allowed the accurate constraint of time relationships between rock units, which were previously poorly limited due to the absence of a biostratigraphy.…”

“…The geodynamic setting that preceded the Palaeoproterozoic phosphogenic event included a surge in tectonic activity that appears to have occurred during the assembly of large continental landmasses in the Neoarchaean (possibly one or more supercontinents) and their wide-spread rifting and break-up in the earliest Palaeoproterozoic (Aspler and Chiarenzelli 1998;Bleeker 2003;Zhao et al 2003;Barley et al 2005). The final separation and dispersion of such large continental landmasses was completed around 2100-2000 Ma, when a plume-related event occurred (Heaman 1997;Barley et al 2005;Halls et al 2008). Breakup of these ancient large pieces of continental crust may have been caused by the development of large igneous provinces (Ernst and Bleeker 2010) and led to the creation of new riftbound Palaeoproterozoic sedimentary basins.…”
