Abstract

Summary

the Asturian margin has been investigated in terms of the gravity signatures derived from all gravity data available. As the area of interest comprises a land/sea transition that has underwent successive tectonic regimes of rifting, passive margin, and compression from Mesozoic to Tertiary times. Then the integration of all gravity data available could help to elucidate the extension of the tectonic structures beyond the area covered by seawaters. Three databases have been used in this study: land gravity, shipborne gravity and satellite altimetry gravity data. From the structural point of view, the residual gravity anomaly map reflects the large tectonic accidents in the basin that coincide, at a general level, with accidents in direction NW-parallel to the fault of Ventaniella and their conjugates of direction SW-NE parallel to the faults of Caldones, Villaviciosa and Lastres.
