Description

The occurrence of rocky and sandy cliffs on the south coast of the Algarve is a consequence of tectonic movement since the Upper Miocene. The Algarve Basin was affected by uplift west of Olhos de Água and subsidence to the east. This process created local sedimentary basins in the easternmost part of the Algarve which filled with sediment throughout the Pliocene and Pleistocene (Moura & Boski, 1999). In contrast to the carbonate sediments formed on the continental shelf during the Miocene, the Pliocene and Pleistocene sediments are mostly siliclastic, deposited in littoral and continental environments. Rapid uplift and consequent erosion produced abundant clastic sediments, which were carried into the regional sedimentary basins.
