| Abstract |
Three sediment cores from neighbouring estuaries along the Portuguese Algarve coast were analysed for the comparison of grain-size distribution, geochemical composition and microfossil associations. The goal of this study is to reconstruct the environmental evolution of the estuaries. Our reconstructions based on foraminifera and ostracods reveal several distinct chronological stages, including the initial situation of the palaeo-valleys, the ingression of the sea into the river mouths at about ~7500-8000 cal BP in the Quarteira and São Lourenço estuaries and ~8000 cal BP in the Carcavai estuary, and the silting-up following the sea-level high stand after ~6500 cal BP until the present. |
