Multi-proxy evidence for subduction of the Neoproterozoic Adamastor Ocean and Wilson cycle tectonics in the South Atlantic Brasiliano Orogenic System of Western Gondwana

•Field, petrographic, geophysical, chronological, elemental, isotopic evidence of a Wilson cycle in the Adamastor ocean realm.•Full oceanic cycle spatio-temporal distribution of rift, passive margin and orogenic basins, MORB/SSZ ophiolites, arc rocks.•Coherent succession of petrologically distinct subduction, collisional and post-collisional igneous suites over 150 Myrs.•Subduction polarity reversal model for Tonian-Cryogenian island arcs followed by Ediacaran continental-margin (Andean) arcs.•Scissor-shaped oceanic basin leads to connected inverted aulacogen/subduction-collision/complex accretionary orogen system.
