“…The Schist Belt consists of a narrow (∼40 km wide) belt of deformed and metamorphosed volcano-sedimentary sequences, with early sedimentation constrained to ca. 810-770 Ma within a series of pre-orogenic rift basins (Percival, Konopásek, Eiesland, et al, 2021;Pertille et al, 2017;Saalmann et al, 2011).…”

“…The Dom Feliciano Belt represents the western half of the southern SANOS extending along the coastlines of southern Brazil and Uruguay (Figure 1b). The Dom Feliciano Belt is the counterpart to the Kaoko Belt and the Gariep Belt in southern Africa (Figure 1b), with the three belts sharing a common pre‐ and syn‐orogenic evolution (Konopásek et al., 2016; Oyhantçabal, Siegesmund, Wemmer, et al., 2011; Percival, Konopásek, Eiesland, et al., 2021). The structure of the Kaoko–Dom Feliciano–Gariep orogenic system is approximately symmetric, comprising an internal hinterland domain characterized by high‐temperature metamorphism and voluminous magmatism, bordered by western and eastern external foreland domains characterized by low‐to medium‐grade metamorphism and fold‐and‐thrust tectonics.…”

“…These units consist of volcanosedimentary sequences deposited between ca. 570–540 Ma (Guadagnin et al., 2010; Oliveira et al., 2014), parts of which are metamorphosed and tectonically interleaved with metasedimentary rocks of the Schist Belt (Battisti et al., 2018; Höfig et al., 2018; Percival, Konopásek, Eiesland, et al., 2021).…”

“…The metavolcanic rocks are predominantly mafic to ultramafic in composition, occasionally associated with minor calc‐silicate layers, and are interlayered within the metasedimentary rocks (Basei et al., 2011; Campos et al., 2011; De Toni, Bitencourt, Konopásek, et al., 2020). Minor layers, lenses, and dykes of felsic volcanic to subvolcanic rocks are also found throughout the complex (Percival, Konopásek, Eiesland, et al., 2021).…”

“…The Brusque Complex protolith is characterized as a series of Tonian rift‐related (Campos et al., 2011; Percival, Konopásek, Eiesland, et al., 2021), a transitional rift to passive margin (Basei et al., 2011; Philipp et al., 2004), or entirely passive margin volcanosedimentary successions (Basei et al., 2018). Early sedimentation in the Brusque Complex basin is constrained to somewhat before ca.…”

Orogenic systems vary widely in terms of their geometry, duration, and scale. The classic collisional orogen can be described using models that involve the termination of a Wilson cycle, where the opening and closing of a large ocean basin between continental bodies culminates in the continental collision. Accretionary orogens, in contrast, form at continental-oceanic convergent plate boundaries in the absence of continental collision, and develop during continuous subduction by crustal thickening due to short-term coupling across the subduction plate boundary (Cawood et al., 2009). Within-plate deformation can also occur away from plate margins, triggered by the transmission of stress from active plate boundaries through the lithosphere (Aitken et al., 2013;Raimondo et al., 2014). Large-scale intracontinental orogens are comparatively less common than collisional or accretionary orogens, but examples are recognized in both ancient and modern settings (Cunningham, 2005;Faure et al., 2009;Hand & Sandiford, 1999). Although the defining characteristics of collisional, accretionary, and intracontinental orogens make them distinct, Cawood et al. (2009) proposed that they represent three interrelated endmembers between which lies a wide spectrum of orogen types. Thus, continental collision at the termination of a Wilson cycle is genetically linked to preceding accretionary orogeny. Similarly, tectonic switching during accretionary orogeny can produce large-scale crustal thickening in within-plate settings (Lister & Forster, 2009), resulting in orogens that develop as the consequence of intracratonic rift inversion, similar to what occurs within an accretionary back-arc setting but at a distance from the developing arc (Collins, 2002;Thompson et al., 2001).The South Atlantic Neoproterozoic Orogenic System (SANOS, sensu Konopásek et al., 2020) comprises an extensive system of orogenic belts that formed during the late Neoproterozoic amalgamation of Western Gondwana

Some recent models challenge the position and extension of the assumed oceanic basins formed through the break-up of Rodinia, and the tectonic processes involved in the Gondwana assembly, making the investigation of the Early Neoproterozoic record of great relevance. Within the South-American Atlantic margin, the Punta del Este Terrane (PET) of the Dom Feliciano Belt (DFB) comprises a unique Tonian to Ediacaran record, and has a strategic position to reconstruct spatio-temporal relationships with the southern African orogenic belts. Novel zircon U–Pb and Lu–Hf data from the PET basement orthogneisses display Tonian magmatic ages (805–760 Ma) and Hf isotopic signatures indicative of mainly crustal/metasedimentary sources, (Nd TDM ages: 2.2–1.9 Ga, and εHf(t): − 12 to − 4). The basement paragneisses yielded late Paleoproterozoic to Neoproterozoic U–Pb ages, but dominantly positive εHf(t) values. The presented results confirm the correlation of the PET with the Coastal Terrane of the Kaoko Belt, and discard the idea of the Nico Pérez Terrane as a source. Detrital zircon U–Pb and Lu–Hf data from the Rocha Formation yielded a main peak at ca. 660 Ma, with the Neoproterozoic grains showing a εHf(t) between + 1 and + 14. The deposition age of the Rocha Formation is constrained by the youngest detrital zircon age peak (660 Ma), and the beginning of the deposition of the Sierra de Aguirre Formation (580 Ma). The data indicate common sources with the Marmora Terrane, and it is thus proposed that the Rocha Formation belongs to the Gariep Belt, and it was juxtaposed during the Ediacaran to the DFB.
