Résumé
This work deals with the spatial distribution of theTortonian marine sediments spread out over the Malaga Basin, with the main objective of estimating rates of vertical movements during the Messinian age. The current maximum topographic altitude from each of the Tortonian outcrops has been corrected by the eustatic variation of the sea level during the sedimentation period and by the Plio-Quaternary uplift. Uplift rates vary between 0.098 m/ky and 0.256 m/ky, showing the highest values toward the North. Regarding on this trend, these rates should not be taken as values of a range for the regional uplift, but as an effect of the regional deformation for that period, fitting a wide folding process related with the relief formation for the whole Betic Chain since the Tortonian age.
