Vintage NE-SW seismic profile (location Figs. 5 and 14) showing the major structural inversion of the Eastern part of the Campidano Graben with the yellow horizon= near Base Samassi and the green horizon= near Base marine Aquitanian-Late Chattian (base SGS). The Monastir Fault is the eastern boundary of the Campidano transpressional basin. The NW-SE oriented inverted structure is mapped on the Geological Map of Sardinia (See Figs. 2A, 3, and 5).
