摘要

A multidisciplinary geological analysis of a trench excavated in the marine estuary of the Guadiana River (SW Spain) has enabled the reconstruction of its palaeoenvironmental evolution over the last 1400 years, from subtidal palaeoenvironments to the current supratidal environments. Its sedimentary record includes three bioclastic sand layers caused by storms (~ 6th–7th centuries CE, 8th–9th centuries CE and 15th–16th centuries CE). These storm-generated layers are characterised by their sedimentological, palaeontological (macrofauna and microfauna) and taphonomic features. The palaeogeographic reconstruction of its adjacent areas explains the establishment of a Roman mausoleum and anchorage during the 4th to 6th centuries CE, in accordance with nearby archaeological findings.
