摘要

The Corsica-Sardinia block is a lithospheric fragment whose recent role in the geodynamics of the central-Western Mediterranean basin is still enigmatic. The most recent regional structure in Sardinia is the Plio-Pleistocene Campidano Basin, which is considered in a 'post-rift' stage since the Middle Pleistocene. New structural and stratigraphic geological surveys along with luminescence ages provide evidence to support an ongoing tectonic activity since the Marine Isotopic Stage 7 (MIS7; ca. 220 ka) on the Sinis peninsula, the structural high that bounds the north-western side of the Campidano Basin. In particular, this paper reveals for the first time the presence of N-S striking normal faults system offsetting late Pleistocene aeolianites (130 +/- 12 ka; 82 +/- 9 ka).
