2. Seismic profiling C. Area east of Sardinia

Although the eastern Sardmian margin has always been considered as a typical passive margin with fault block systems arranged in a half-graben pattern, we have recognizcd evidcnce of compressional deformation west of the Central Fault: reverse faults and inverted basins. Our initial hypothesis is that the latter structures, which occur only in this area, are due to a transpressive component along north-south trending faults. Interesting morphological features, clearly visible along this seismic line, are a number of erosional channels, about 100 m dcep and a few kilometres wide. These erosional features belong to the sinuous Sardinia Valley, which comes from the Sardinian margin.
