Shear belts developed at the block borders due to oblique plate convergence. A consistent litho-structural zoning may be observed along the border zones of the blocks: the known high-grade terrains are exposed along the upper block border and pass to distal granite-greenstone terrains; in the lower block, granite-greenstone terrains form the older basement, and supracrustals occur as a metavolcano-sedimentary belt near or adjacent to the suture. This regional litho-structural framework may be related to diachronous collisions of sialic masses which lead to their amalgamation into an extensive continental mass. -from English summary7-31pormetamorphismmobile beltorogenesisPrecambrianshear zonetectonic evolutionBrazilArtigoAcesso restrito2-s2.0-0027869072
