Chronostratigraphy of the area of Carmona based along an industrial seismic profile including three deep industrial boreholes and this work. A, The Carmona area from Google Earth image with plotted seismic profile and industrial boreholes and location of the studied cross profile (Fig. 3). B, Interpreted seismic profile and industrial drilled sections showing the different lithostratigraphic and biostratigraphic units and their boundary age according to Ledesma (2000) − some ages are updated with respect to Hilgen et al. (2012) − contrasting with the studied cross profile (Fig. 5). The figure emphasizes the diverse types of erosion and their age that affected the area of Carmona in the late Messinian. The red arrow pinpoints the level of deposition in the marine basin of the eroded material from the Caliza Tosca. The light grey lines indicate sedimentary more marked reflectors. The dark grey lines indicates the thick turbiditic reflectors.
