Litostratigrafia do Cenozóico de Portuga

Abstract

In Portugal mainland the Cenozoic record occurs largely in several basins. Even in the same basin, the sedimentary record shows meaningful lateral facies and thickness changes. However, the main sedimentary ruptures and overall lithologic characteristics of the infillings stades are quite similar in the same basins, as a result of the geodinamic evolution of Iberia and the Cainozoic times eustatic and climate changes. A stratigraphic framework is proposed in order to allow a less complex use of the lithostratigraphic units as referred in the geological maps and literature. Some topics for future research are suggested.
