“…Different models for the boundaries of these provinces have been proposed. Based on increasing availability of radiometric dates, the model of Tassinari and Macambira (1999) and Tassinari and Macambira (2004) has evolved through Cordani et al (2016), Teixeira et al (2019), Macambira et al (2020), andJohansson et al (2021).

The seismic structure of the South American mantle, especially beneath the stable continental interior, has not been studied on a regional scale, with limitations in heterogeneous resolving power caused mainly by a dearth of seismographic stations outside the Andes Mountains. The continent is composed of three main tectonic domains (Figure 1: the Archean-Proterozoic South American Platform, the Phanerozoic Patagonian Platform, and the active Andean Belt. The stable platforms are composed of several cratons and cratonic blocks (Figure 1) amalgamated in the Neoproterozoic to form the Gondwana supercontinent. In this stable interior, several regional scale tomographic studies using teleseismic

“…For instance, 1800-1740 Ma zircons are absent in the studied sample, whereas this age interval corresponds to the time of active intraplate magmatism in the Ukrainian Shield [55,56,57]. Zircons with ages of 2150-2050 Ma are also absent in the studied sample, whereas rocks of this age are widely distributed in the Ukrainian Shield [58,59,60,61]. The studied sample contains a small number of ca.…”

“…Many studies have suggested a strong link between Baltica and Amazonia during the Proterozoic (e.g., [56,61,72,73].

We used LA-ICP-MS U-Pb data for detrital zircon to constrain the Maximum Depositional Age (MDA) and provenance of clastic sedimentary rocks of the Volyn-Orsha sedimentary basin, which filled an elongated (~625×250 km) depression in SW Baltica and attained ~900 m in thickness. Eighty-six zircons out of one hundred and three yielded concordant dates, with most of them (86 %) falling in the time interval between 1655 ± 3 and 1044 ± 16 Ma and clustering in two peaks at ca. 1630 and 1230 Ma. The remaining zircons yielded dates older than 1800 Ma. The MDA is defined by a tight group of three zircons with a weighted average age of 1079 ± 8 Ma. This age corresponds to the time of a clockwise ~90° rotation of Baltica and the formation of the Grenvillian – Sveconorwegian – Sunsas orogenic belts. Subsidence was facilitated by the presence of eclogites derived from subducted oceanic crust. The sediments of the Orsha sub-basin in the northeastern part of the basin were derived from the local crystalline basement, whereas the sediments in the Volyn sub-basin, extending to the margin of Baltica, were transported from the orogen between Laurentia, Baltica, and Amazonia.

“…This temporally and spatially extensive accretionary belt, the Great Proterozoic Accretionary Orogen (Fig. 3) (GPAO; Condie, 2013;Roberts, 2013), produced calc-alkaline I-type magmatism and significant crustal growth along the margins of SE Laurentia, SW Baltica and SW Amazonia (Whitmeyer and Karlstrom, 2007;Johansson, 2009;Johansson et al, 2022). The extent of the GPAO around the entirety of the Columbia supercontinent is not well constrained, but likely included other continents where magmatism of this timeframe is known (e.g., Kalahari, North China Craton, Siberia, India; Li et al, 2021;Wang et al, 2022;Roberts, 2013;Elming et al, 2021).…”
