| Zusammenfassung |
| Detailed tectonic analyses and geological mapping in muddy fold-belt front is a hard target. Using both fieldwork and GIS software associated to new soil datations of the different marine terrassic levels of the Tarento Gulf (Southern Italy) we were able to re-interprete from an active tectonic point of view the deformation front of southern Apenines. Furthermore by combining our data with the known eustatic curve of the mediteranean sea along the southern italian shore, we were able to decipher the landscape evolution of the southern Apenines deformation front and we are now able to differenciate the geomorphic signal of both active tectonic and eustatic processes and their related geomorphic features on the Tarento Gulf marine terrasses. Therefore the two passed seismic cycle of the Southern Apenine deformation front are revealed herein and appear to be coherent with both a regular intersismic linear creep period (time =240 ka/uplift=70m) and a rapid cosismic uplift (time :10Ka/uplift = 45m). This study give us new inputs to better understand the deformation front of Southern Apenine (Italy) which is of prime importance today in European Geoscience as well as italian "Protezione Civile Nazionale". |
