Abstract
The present report, consisting of three chapters, is devoted to the evolution of the Atlantic coastal zones of Africa and South America in the Quaternary.In Africa, long-term (epirogenic), medium-term (combination of previous and climatic) and short-term (climatic and oceanographic) changes have been studied and their influence on coastal development is described herein.In South America, it is shown that the principal factors in coastal zone evolution have been sea-level fluctuations, availability of sandy sediments, wave and long-shore current dynamics and coastal features propitiating entrapment of sediments. In the central part of the Brazilian coastline, three high sea-level have been identified in the Quaternary.
