Litostratigrafia do Terciario da região Miranda do Corvo-Viseu (Bacia do Mondego, Portugal)

The lithostratigraphic units (2 groups, 5 formations and 4 members) of the Tertiary of the Miranda do Corvo-Viseu region (Central Portugal) are here described. For each unit the characterization and description (boundaries, diagnostic properties and atributes) were included. The stratigraphic, lithological, sequential and tectonic data allow correlations with other units of the same Tertiary basin located more to west and support the chronostratigraphic attribution. Sedimentologic characteristics of the deposits lead to the interpretation of the influence of tectonism, climate and eustasy during the sedimentary evolution of this Basin.

Transição do enchimento terciário para o encaixe fluvial quaternário na área de Vila Velha de Ródão (sector NE da Bacia do Baixo Tejo)

The geomorphologic characteristics and lithostratigraphic units of the transition from the Tertiary filling stage to the Quaternary fluvial incision in the Vila Velha de Ródão area (Lower Tagus Basin, NE sector) are presented. Several morphodynamic episodes, which had an important tectonic control, were distinguished. The same main morphosedimentary processes can be identified in other areas of this important river basin. Five periods of Quaternary fluvial incision were characterized.
