Abstract

In order to undertake correlative studies between the landforms and the ecology of the swamp and dune systems of the State of Veracruz, Mexico, a general geomorphological map (morpho-chrono-genetic) was produced. The map shows the coastal environment of the morphostructural units Basin Tampico-Misantla, Massif of Teziutlán and Basin of Veracruz. The basic principles of the morphogenetic classification include: I- basic categories of the relief; IIaltitudinal levels of the relief subcategories; III- specific morphogenetic type; and IV- relative dating of the relief. A final discussion focuses on the regional morphogenetic regularities and the fundamental stages of relief formation, consolidation and evolution during the late Pliocene and Quaternary, including the regional units of the Massif Los Tuxtlas, and Saline Basin of the Isthmus. From the regional point of view, the main morphostructures (Basin Tampico-Misantla, Massif of Teziutlán, Basin of Veracruz, Volcanic Massif Los Tuxtlas and Saline Basin of the Isthmus) presents morphogenetic features of the relief that evidence different tectonic trends during the Quaternary. In the context of Basin of Veracruz stand out the morphostructural steps: a) Mixquetilla, (b) Lower basins of Limón and Acula rivers, (c) Lower basins of Papaloapan, San Agustín and San Juan rivers, and (d) Cinapa.
