We reconstruct the structure and geodynamics of the Balearic basin based on deep seismic reflection data from the CROP and CROP-ECORS projects.

Abstract

We reconstruct the structure and geodynamics of the Balearic basin based on deep seismic reflection data from the CROP and CROP-ECORS projects. An interpretative processing (IP) sequence and innovative velocity filtering techniques were exploited to reprocess most of the CROP seismic lines from the area, and to enhance deeper crustal events. The resulting good quality data now image the slab of the Alpine-Tethys oceanic crust, subducted in the Balearic stage (Oligocene–Lower Miocene). Such an interpretation supports the idea that rotation of the Corso-Sardinia block in the Balearic geodynamic stage was driven by W-dipping subduction of the Alpine-Tethys lithosphere. In all the seismic sections examined in this work, the rift tectonics of both the margins of the Balearic Basin and the ocean–continent boundary are well evident.
