“…Rodinia is thought to have been assembled between 1.3 and 0.95 or 0.9 Ga (Condie, 2003;Li Z X et al, 2008a), and after that it experienced a prolonged process of supercontinent breakup. Recent studies from different localities around the globe, such as North America, South Africa and India have recognized large-scale late Mesoproterozoic intraplate magmatism, which is represented by 1.2-1.1 Ga alkaline and mafic-ultramafic rocks typical of rift settings (e.g., Hanson et al, 2004;Pradhan et al, 2012;Ernst et al, 2013;Teixeira et al, 2015). Such intraplate magmatism took place while continental collision related to Rodinia assembly reached its climax at most of the Rodinia-forming continents, and has been attributed to LIP event related to mantle plume activities (e.g., Chroudhary et al, 2019).…”

South China as an amalgamation of the Yangtze and Cathaysia blocks is composed of Archean to Mesoproterozoic basement overlain by Neoproterozoic and younger cover. Both the constituent Yangtze and Cathaysia blocks contain well‐preserved Neoproterozoic rocks that have been extensively studied in terms of the age and tectonic nature, but less is known about their earlier crustal history due to the incomplete rock record. Recent efforts in investigating the yet survived crustal nature based on isotopic and elemental signatures preserved in igneous and sedimentary rocks have steadily improved our knowledge about the pre‐Neoproterozoic continental crustal evolution in South China. In this paper, we summarize the up‐to‐date pre‐Neoproterozoic records, including petrological, geochronological, geochemical and geophysical data, across South China, and discuss its spatiotemporal patterns of the pre‐Neoproterozoic crust and the relevant tectonic events. While the xenocrystic/inherited and detrital zircon records suggest widespread Archean (mainly ca. 2.5 Ga) crustal components within both the Yangtze and Cathaysia blocks, exposed Archean rocks are only limited to isolated crustal provinces in the Yangtze Block. These Archean rocks are dominated by TTGs (tonalite‐trondhjemite‐granodiorite) with varied ages (3.3–2.5 Ga) and zircon Hf isotopes, indicating a compositionally heterogeneous nature of the Archean Yangtze Block and, by inference, the development of multiple ancient terranes. The early Paleoproterozoic (2.4–2.2 Ga) tectonomagmatic events characterize the western Yangtze Block and are supportive of an east‐west subdivision of the Yangtze basement, whereas the late Paleoproterozoic (2.1–1.7 Ga) orogeneses may have affected a larger area covering both the western and eastern parts of the Yangtze Block, and also the Cathaysia Block. The eastern Yangtze Block with generally northeastward‐younging late Paleoproterozoic magmatism and metamorphism likely experienced a prolonged 2.05–1.75 Ga orogenic process welding the various Archean proto‐continents, consistent with the documentation of a buried late Paleoproterozoic orogenic belt imaged by deep seismic profiling from its central part and of a slightly older ophiolitic mélange in the northern part. The Cathaysia Block was probably involved in a short‐lived 1.9–1.8 Ga orogenic event. The two orogeneses overlapped in time and may have contributed to the cratonization of a possible unified South China, and are referred to be linked with the assembly of the Nuna Supercontinent. The subsequent late Paleoproterozoic to early Mesoproterozoic rift successions and intrusions (1.7–1.5 Ga) in the southwestern Yangtze Block, and the ca. 1.43 Ga rifting in Hainan Island of the Cathaysia Block could be responses to the Nuna break‐up. Late Mesoproterozoic (1.2–1.0 Ga) magmatism of varied age and nature in different localities of the Yangtze Block is reflective of a complex tectonic process in the context of the assembly of the Rodinia Supercontinent. Similar‐aged metamorphism (...

“…5) suggest different potential source areas, both in southern Africa and South America. The lack of paleocurrent data indicative of fluvial and/or deltaic sediment-routing systems flowing from north to southern areas of the Paran a Basin, lead us to discard some possible northward Grenville-age source areas such like as: (i) the <1.21 Ga mafic-ultramafic rocks of the Nova Brasilândia Belt (Teixeira et al, 2010) in Mato Grosso and Rondonia states (Brazil), (ii) the 1110e1112 Ma Rinc on de Tigre-Huanchaca Large Igneous Province of the eastern Bolivian SW Amazonian Craton (Teixeira et al, 2015), and (iii) the 1.20e0.95 Ga Suns as-Aguapeí Province of eastern Bolivia (Teixeira et al, 2010). They are somewhat younger than those derived from the Namaqua-Natal Belt of western Kalahari craton, where juvenile crust formation occurred during two principal periods at ca.…”

The Late Permian sedimentary succession of the Paran a Basin, southern Brazil, provide a valuable source of information about sediment provenance, tectonic processes and, consequently, the paleogeography of the southwestern Gondwana supercontinent. In order to understand the patterns of sedimentary dispersal and reconstruct the Late Permian source-to-sink dynamic, we report a complete series of U-Pb ages and Hf isotopic compositions of detrital zircons from the Rio do Rasto Formation sandstones allied with detailed paleocurrent and sedimentologic data. Our integrated provenance study reveals a consistent sediment transport from the south to the north and northwest. According to the evaluation of zircon ages and Hf isotopes, it was possible to determine four distinct source areas: (i) a distant Late Paleozoic active magmatic arc located in the southwestern Gondwana margin (i.e. Gondwanides Orogen), corresponding to the North Patagonian Massif; (ii) recycling of orthoquartzites from the uplifted Paleozoic Ventania Fold Belt and immature sandstones from the Claromec o Foreland Basin in centraleastern Argentina and the Silurian-Devonian successions of the southern Paran a Basin (central-northern Uruguay) and North Patagonian Massif; (iii) exhumed areas of the Archean-Paleoproterozoic basement and Neoproterozoic to Early Paleozoic mobile belts of the Damara in southwestern Africa and Ribeira Fold Belt in Uruguay and southern Brazil; and (iv) southeastward provenance of Grenvillian (1.2 e1.0 Ga) zircons coming from the mafic to intermediate Mesoproterozoic igneous units of the Namaqua-Natal Belt in South Africa and Namibia. These data allow us to argue that sediments deposited in the Paran a Basin during the Late Permian come from both short-and long-distance source areas. In this context, an important population of Permian detrital zircons comes from the Gondwanides Orogen in the south, probably carried by transcontinental alluvial systems. Close to the source area, antecedent river channels would have eroded older sedimentary rocks of the Ventania Fold Belt, Claromec o and Chaco-Paran a basins and North Patagonian Massif, crosscutting a peripheral bulge and flowing towards the alluvial plain of the intraplate setting to areas further north. Concomitantly, these sediments are reworked by strong winds that even helped carrying the grains to the Paran a Basin depositional site.

“…Additional U -Pb provenance studies for the Aguapeí Group indicated a wide age range for the main sources of the sedimentary protholiths, compatible with the geologic framework of the RNJ and RSI provinces (Geraldes et al 2014;Rizzotto et al 2014). It is worth mentioning that the Huanchaca Group is intruded by mafic sills that are part of the 1.11 Ga Rincón del Tigre-Huanchaca LIP (Teixeira et al 2015) that marks the youngest mantle plume activity in Amazonia predating Rodinia breakup (Lima et al 2012;Teixeira et al 2015).…”

“…In this regard, the respective timing of cratonization (minimum ages) can be inferred by precise ages of diachronic variation of the anorogenic activity such as rapakivi suites, mafic -ultramafic complexes, mafic dyke swarms and sequences of undeformed volcanic-sedimentary cover within or across the province (s) (e.g. Geraldes et al 2004aGeraldes et al , 2014Tassinari & Macambira 2004;Cordani & Teixeira 2007;Teixeira et al 2011Teixeira et al , 2015Girardi et al 2012). Notably, regional spatial and temporal correlations in the intraplate magmatism coupled with paleomagnetic evidence have provided constraints on the role of large igneous provinces (LIPs) during Proterozoic time, particularly related to Amazonia's potential relationships in supercontinent cycles such as the assembly and breakup of Columbia (or Nuna) and Rodinia (e.g.…”
