Structural depth maps of three horizons in the central-southern Campidano survey (Igia) with location of the profiles presented: A. Base of the syntectonic continental Pliocene Samassi Formation resting directly on deformed Tortonian. Note thick depocentres (1000 m) and inversion of the E area with erosion of the Miocene. B. Base post-rift Middle-Lower Burdigalian C- Base marine syn-rift Late Oligocene-Aquitanian (Base SGS). The overall tectonic pattern is a wrenched trans pressive basin bounded by Oligocene-Miocene faults reactivated from the Late Miocene to the Recent under a N-S compressional stress.
