Early Permian 90° clockwise rotation of the Maures?Estérel?Corsica?Sardinia block confirmed by new palaeomagnetic data and followed by a Triassic 60° clockwise rotation

Popis výsledku v původním jazyce

Palaeomagnetic investigations of the Corso-Sardinian block and Maures?Estérel show that there has been a change in their magnetic orientation during the Late Carboniferous?Early Permian period (305?280 Ma). This trend is interpreted in terms of a large-scale 90° clockwise rotation of the southern branch of the Variscan belt that matches the successive change in shortening directions revealed by structural geology. The evidence is based on existing structural studies of the fabrics of syntectonically emplaced granitoids partly based on the anisotropy of magnetic susceptibility, combined with a large database of isotopic ages. The chronological match between the palaeomagnetic and tectonic datasets is interpreted here as a result of large-scale dextral wrench movements in the lithosphere between the Gondwana and Laurussia supercontinents. This wrench deformation is regarded as a sequel to the dextral rotation of the northern branch of the Variscan belt during 330?315 Ma which terminated
