A South America – Baltica (SAMBA) model with the position of Amazonia, West Africa, and Baltica during the 1.8 to 1.3 Ga period, with the location of magmatic cycles investigated here and radial dyke swarms related to the Yanomami (1.98 Ga14) and Avanavero (1.79 Ga30) large igneous provinces. Modified from ref. 18. Ophiolites: M- Mako87, J- Jormua88 and T- Trincheira24. Eclogite: S- Salma89. B Chronostratigraphic map of the Amazon Craton (the southern Paraguá and Rio Apa domains are not shown in this figure, as their inclusion would alter the map scale and reduce the detail of the LIP–SLIP units and sample locations). The magmatic cycles indicated in the legend are interpreted in this work. Modified from ref. 22.
