English: Alvor , Algarve, Portugal October 2015
The Algarve stands out as unique stratigraphic and morpho-tectonicregion. A peripheral Carboniferous unit of the Variscan orogeny, it constitutes the Mesozoic and Cenozoic sedimentary layers, deposited onto two totally distinct superimposed basins. Between the Middle-Upper Triassic to Hettangian, sediments evolved from continental (fluvial red sandstone) to shallow marine over the entire region, which included instances of evaporates, tholeiite fissural magmas In Algarve, chiefly marine units from Lower to Upper Miocene are well developped. The Lower unit (Lagos-Portimao Formation) is best exposed in Western Algarve, but desappears eastwards. Middle Miocene is not as well known, whereas Upper Miocene main outcrops are in Eastern Algarve. Cacela Formation is remarquable for its beautiful fossils. Sedimentation as a whole refletcts thetectonic activity and in special the evolution of the Algarve flexures. There is scant evidence of post-Lower Miocene volcanism, the latest known in Portugal. Pliocene has not been recognized there beyond doubt. |
