Abstract
Geological peregrination in the south-west coast of Portugal.
A b s t r a c t. Portugal as a country of outstanding geological interest was the goal of a scientific expedition of the Polish Salt Mining Association in September 2019. The paper presents the outline of the geology of Portugal, especially the Lusitanian and Algarve sedimentary basins, and the main geological sites along the route of the expedition, i.e. sites documenting stratigraphy and tectonics of the Mesozoic and Cenozoic formations on the central-western and southern Atlantic coast, sites related to the occurrence of salt diapirs and salt tectonics, salines and monuments of nature with preserved dinosaur footprints. Moreover, as Portugal is a country of high seismic activity, the history of the largest earthquake in historical times in the Lower Tagus Valley is presented.
