摘要

•Várzea do Capivarita Complex orthogneisses demonstrate Tonian protolith ages.•Várzea do Capivarita and Porongos complexes shared an igneous history at ca. 790 Ma.•Várzea do Capivarita Complex has a syn-volcanic–sedimentary origin at ca. 790 Ma.•Dom Feliciano Belt ca. 790 Ma zircon crystallized in the more evolved magmas.
