Résumé
This work includes the first contributions of the multidisciplinary study carried out in the Quaternary deposits of Los Aljezares Natrual Site (Aspe, Alicante). This site is located in a depressed area surrounded by topographical elevations only interrupted by the entrenching of the Vinalopó River from N to S. The Quaternary deposits show continuous flat tops in similar topographic level, suggesting fluvial terraces of the Vinalopó River. However, this study has allowed us to associate these deposits with the filling of a sedimentary basin forme d previously to the entrenching of the river. The Quaternary deposits consist of gravel and coarse sand, and lutites and fine sands that would respectively show proximal and distal facies of alluvial systems coming from the surrounding reliefs, and leaving in the central area a lacustrine palustrine zone. Additionally, lithic industry has been identied in these deposits in a recent geoarchaeological survey, allowing us to attribute them to a Upper Pleistocene age. Moreover, three stages in the configuration of Los Aljezares Natural Site have been established: i) a first erosional stage leaving the paleorelief where the basin is developed; ii) the sedimentation of the Quaternary deposits and iii) the entrenching of the Vinalopó River.
