In the central part of the Ebro basin, filled with Neogene beds, more than 6000 lineaments have been mapped at a 1 100 000 scale, using a combination of bands 2, 4 and 7 of the Landsat Thematic Mapper (TM). With an automatic exploration program, geometric features of the lineament population were analysed, identifying four sets of lineaments trending NW-SE, ESE-WNW, NNE-SSW and NE-SW. Field studies reveal that most lineaments are normal faults. The highest density lies over a lax NW-trending syncline, where the Tertiary thickness is lower and the basement shows NW-trending faulting. It is thus concluded that the lineaments developed as a result of cover deformation above large basement faults.
