Synopsis

This monograph intends to be a complementary training tool for field activities on Geology. The beaches of Sines consist of sand that is transported seasonally along and across the coast. Variations in the wave energy dissipated on the beach influence sediment transport and are responsible for the variation in sand size. The sand on the beaches of Sines contains heavy minerals, including zircon. U-Pb geochronology of detrital zircon allows the identification of sedimentary sources of beach sand. When comparing the age populations of detrital zircon found in the beach sand with those that characterize the sedimentary, igneous, and metamorphic rocks of the sea-cliffs and other areas further away from the coast, we can recognize what their sedimentary sources may have been. This information is relevant to try to reconstruct the geological evolution of a given region.
