A comparative study of Precambrian and Mesozoic tholeiitic basalt magmatism from the South American Platform reveals that both Late Archaean–Proterozoic and Mesozoic tholeiites are characterized by high TiO2 (>2 wt.%; HTi) and low TiO2 (

The Rio de La Plata craton in Argentina (Azul and Tandil regions) is characterized by Early Proterozoic (2·0 Ga) calc-alkaline and Middle Proterozoic (1·6 Ga) tholeiitic dyke swarms intruding the crystalline basement involved in the Transamazonian
