Early Precambrian basic rocks of South America (2.7Ga), Transamazonian (2.0Ga), Uruaçuano–Espinhago (1.5–1.1 Ga) and Brasiliano (1.1–0.5 Ga) Cycles (see Wernick, 1981), during which the Precambrian crust progressively accreted. It has been estimated that 80% of the Precambrian of South America had formed by the end of the Transamazonian (Cordani ., 1988).

In addition, early to mid-Proterozoic hypabyssal basic intrusions occur in virtually all of the Archaean cratonic regions, while early to mid-Proterozoic metavolcanic suites occur throughout western central USA (Condie, 1986).
