          Abstract

          Com a perspectiva de mapear geomorfologicamente a área englobada pelas folhas Alhandra e Pitimbu, adotou-se a metodologia taxonômica do relevo. A escala 1:25.000 admitiu identificar os seis táxons: Bacia Sedimentar Pernambuco-Paraíba (1° táxon); Tabuleiros Litorâneos, Baixada Litorânea e Depressão do Abiaí (2° táxon); nos 3° e 4° táxons, registraram-se as unidades morfológicas denudacionais (tabulares, convexas e semiconvexas) e agradacionais (planícies interdidais, marinha e fluviais; terraços marinhos e fluviais e colúvios); as vertentes retilíneas (5° táxon); as menores formas mapeáveis: voçorocas, dobras e falhas (6° táxon). Considera-se a importância da pesquisa ao contribuir para o planejamento ambiental.

          In order to carry out the geomorphological mapping of the area encompassed by the Alhandra and Pitimbu Leaves, the taxonomic methodology for relief was adopted. The 1:25.000 scale made it possible to identify six taxa: Pernambuco-Paraíba Sedimentary Basin (1st taxon); Coastal Tableland, Coastal Lowlands and Abiaí Depression (2nd taxon); denudational (tabular, convex and semi-convex) and aggradational (intertidal, marine and fluvial plains; marine and fluvial terraces and colluviums) morphological units (in the 3rd and 4th taxa); rectilinear slopes (5th taxon); and the smallest mappable forms: gullies, folds and faults (6th taxon). The importance of this research project is its possible contribution to environmental planning.

          Con la perspectiva de mapear geomorfológicamente el área englobada por las hojas Alhandra y Pitimbu, se adoptó la metodología taxonómica del relieve. La escala 1:25.000 permitió identificar los seis taxones: Cuenca Sedimentar Pernambuco-Paraíba (1° taxón); Tableros Litorales, Bajada Litoral y Depresión de Abiaí (2° taxón); en los 3° y 4° taxones, se han registrado unidades morfológicas denudacionales (tabulares, convexas y semiconvexas) y agradacionales (llanuras interdidales, marina y fluviales; terrazas marinas y fluviales y coluvies); las vertientes rectilíneas (5° taxón); las menores formas mapeables: erosiones, pliegues y fallas (6° taxón). Se considera la importancia de la investigación por aportar a la planeación ambiental.
