Résumé

This work deals with the spatial distribution of the Pliocene marine sediments spread out over the Malaga Basin, with the main objective of estimating rates of vertical movements during the Plio- Quaternary. The current maximum topographic height from each of the Pliocene outcrops has been corrected by the altitude of the sea level during the sedimentation period. The estimated rates of vertical movement vary between 0.005 and 0.091 m/ky, showing two trends: one of them increasing westward, and the other increasing from the centre of the basin to both the northern and nouthern borders. The former, includes subsidence areas at the eastern part of the basin, as well as the highest values at the western border. The later, should respond to wide folding deformation, which builds up the basin into two synclines separated by the anticline of Cártama. Finally, four normal faults affecting Pliocene sediments have been identified, showing vertical movements rates of 0.02-0.03 m/ky since the Lower Pliocene.
