ABSTRACT
The Kaoko and Dom Feliciano fold belts resulted from the collision between the Rio de la Plata and Congo-Sao Francisco plates, whereas the Gariep and the Malmesbury belts recorded the collision between the Rio de la Plata and Kalahari plates. The northern part of the Dom Feliciano fold belt, in the State of Santa Catarina, was the subject of a detailed study which will be used as reference. As far as the Brasiliano cycle is concerned, the proposed intracontinental interpretation contrasts strongly with the oceanic models advanced for the median segment of the Dom Feliciano fold belt in Rio Grande do Sul, which some authors also extended to the northern segment. The northern portion of the Dom Feliciano fold belt has a sialic substratum. The basement reappears there as in-liers in the intermediate zone. The lavas, represented by andesites, porphyritic latites, ignimbrites, and tuffs, are also alkaline.
