“…Recent paleotectonic models quoting the Statherian anorogenic magmatism suggest a paleocontinental link between the São Francisco and North China cratons (Peng 2015, Cederberg et al 2016, Teixeira et al 2017Xu et al 2017). These authors point to similarities between the Pará de Minas dyke swarm, located in the southern tip of the São Francisco craton, and the magmatism related to the Xiong'er-Taihang LIP event, both interpreted as related to Statherian intracontinental setting (Fig.…”

The Espinhaço rift system encompasses taphrogenetic events from the Statherian to Tonian in the São Francisco-Congo (SFC) paleocontinent. The magmatism is represented mainly by metamorphosed anorogenic granites and rhyolites with subordinate amphibolites. Zircon U-Pb (LA-ICPMS and SHRIMP) ages from felsic (1748 ± 3 Ma and 1740 ± 8 Ma) and mafic (1725 ± 4 Ma) rock samples, coupled with previous studies suggest that the Espinhaço igneous province erupted from ca. 1.79 Ga to ca. 1.70 Ga. The felsic rocks show characteristics of A-type magmas. The negative εHf(t) data for meta-rhyolite zircons (-12.32 to -17.58), the moderate δ 18 O values (7.02 to 7.98) and the REE patterns suggest crustal melting related to an extensional environment. The mafic rock shows negative values of εHf(t) in zircons (-4.05 to -8.25) and moderate δ 18 O values (5.56 to 7.87). The results disclose a basaltic magmatism in continental intraplate setting whose parental magma could have been derived from the subcontinental lithospheric mantle with contamination of crustal material. These data coupled with coeval Espinhaço magmatism and mafic dyke swarms found to the south of the Espinhaço rift system reinforce the evidence of a long-lived Statherian silicic large igneous province (SLIP) on the SFC paleocontinental block.

“…Geological processes linked to the existence of supercontinents include, among others, concepts such as mantle superplume events, LIPs and fragmentation of continental dyke swarms (Ernst, 2014), matching of conjugate orogenic belts (Hoffman, 1991) and major rifts (Dalziel, 1999), and the concept of true polar wander (Evans, 2003). A revised Columbia (Nuna) reconstruction, supported on available paleomagnetic data of Pesonen et al (2012) and Xu et al (2017) and based on matching of 1.79−1.75 Ga LIP fragments (mafic dykes, sills, volcanics) from different cratonic blocks, is presented in this section. Remnants of LIPs and associated rift sequences are used on repositioning of three Statherian plume centers in Columbia (Nuna).…”

“…3a. Xu et al (2017) also reported the results of anisotropy of magnetic susceptibility (AMS) of the 1.79 Ga Xiong'er volcanic rocks. The inferred magma flow directions from the AMS results revealed a radial flow pattern with an eruption center located near Xiong'er Mountain on the south margin of the North China craton.…”

“…After Xu et al (2017), a comparison of geological and paleomagnetic results from Statherian mafic dykes and volcanics suggests the positioning of the North China craton between São Francisco-Congo, Rio de la Plata and Siberia (Fig. 3d) in the Nuna/Columbia supercontinent.…”

“…India has been tentatively positioned near Australia (Zhang et al, 2012;Pesonen et al, 2012). By using paleomagnetism and anisotropy of magnetic susceptibility (AMS) of the Xiong'er volcanics, Xu et al (2017) positioned North China craton between São Francisco/Congo, Siberia and Rio de la Plata cratons in the Statherian period. Pesonen et al (2012) and Rogers and Santosh (2002) indicated that maximum packing of the Columbia (Nuna) supercontinent likely occurred around 1.5 Ga.…”

Supported on available paleomagnetic data, a new Columbia (Nuna) supercontinent reconstruction is proposed based on matching U-Pb-dated 1.79-1.75 Ga Large Igneous Province (LIP) mafic unit fragments and particularly on linking their dykes into radiating systems. Information from the literature is augmented with the herein dated 1762 Ma (U-Pb) Januária dyke swarm from the São Francisco Craton (Brazil). In this reconstruction, three major LIPs would be restored. The first one (1.79 Ga Hart-Carson LIP), would consist of the Hart sills and Carson volcanics, and the Pebbair mafic dyke swarm. The second one (1.79-1.78 Ga Avanavero-Xiong'er LIP), would be composed of Avanavero sills and dykes, Taihang and Xiong'er dykes along with volcanics, Pará de Minas-1 dykes, Uruguayan/Florida dykes, Tomashgorod-Belokorovichi dykes and related intrusives, Oskarshamn dykes, and Libiri dykes. The third one (1.76-1.75 Ga Timpton LIP), would comprise the Timpton radiating swarm, Newer dolerites, Januária dykes, Kédougou dykes, Tagragra of Akka dykes, Vestfold Hills-3 dykes, Kivalliq suite, Subbottsy-Nosachev dykes and intrusives, and Pugachevka-Fedorovka dykes and intrusives. Additionally, it is suggested that the model of supercontinent-superplume coupling (previously applied to Rodinia and Pangea supercontinents) represents a possible geodynamic framework for Columbia (Nuna) during the beginning of the Statherian Period.
