Abstract
EVOLUÇÃO GEOMORFOLÓGICA DE PLANÍCIES COSTEIRAS NO HOLOCENO
Highlights
Brazil’s coastline is the longest in Latin America, it is about 7,367 km (IBGE, 2011), long and has a wide geological, geomorphological and oceanographic diversity, under conditions of tectonic stability
Several evolutionary models have been developed on coastal plains with similar characteristics (MARTIN et al, 1980; LESSA et al, 2000; TOMAZELLI and VILLWOCK, 1996; DILLENBURG et al.; 2000; DOMINGUEZ et al, 1990; MARTIN et al, 1996; GUEDES, 2009)
An evolution model was developed for this segment (DOMINGUEZ, BITTENCOURT, MARTIN, 1981) based on eight phases of marine regression and transgression, driven by wet and dry climatic phases (BITTENCOURT et al, 1979; MARTIN et al, 1979)
Summary
Brazil’s coastline is the longest in Latin America, it is about 7,367 km (IBGE, 2011), long and has a wide geological, geomorphological and oceanographic diversity, under conditions of tectonic stability Due to this variety, different proposals on how the coast should be compartmentalized have been put forward. One of the most well-known partitions was developed by Silveira (1964), who divided the Brazilian coastline into five main sectors, namely, the North, Northeast, East, Southeast, and South coasts In these areas, several evolutionary models have been developed on coastal plains with similar characteristics (MARTIN et al, 1980; LESSA et al, 2000; TOMAZELLI and VILLWOCK, 1996; DILLENBURG et al.; 2000; DOMINGUEZ et al, 1990; MARTIN et al, 1996; GUEDES, 2009). Eustatic processes were the main factors responsible for the development and evolution of the coastal plains located in this part of the coast, exemplified by the plains of the Jequitinhonha, Doce and Paraíba do Sul rivers
