The Neogene of Algarve (Portugal)
Pais, João; Legoinha, P.; Elderfield, H.; Sousa, L.; Estevens, M.A synthesis about the Neogene and Quaternary of Algarve (Southern Portugal) is presented. New isotopic 87Sr/86Sr ages as well as biostratigraphic data about the Miocene deposits allow to present a new stratigraphic frame for the previously characterized units. The Lagos-Portimão Formation corresponds to deposits of temperate carbonate platform sedimentological type, developed during a long time span (Lower Burd...
A stratigraphic framework for the Miocene from the lower Tagus Basin (Lisbon, S...
Legoinha, P.; Pais, João; Antunes, M. Telles; Elderfield, H.Rev. Soc. Geol. España, 12(1), ano 1999 ; Lithostratigraphy, main biostratigraphic events (first and last ocurrence), 87Sr/86Sr as well as KlAr isotopic ages, are presented for the Lower Tagus basin (LTB) Miocene (Lisboa and Peninsula de Setubal regions). Eight depositional sequences (DS) delimited by regional disconformities related with transgressive surfaces are defined. The main features of the Depositiona...
