Morphostructural evolution and uplift rates of the western side of the upper Agri River valley, southern Apennines, Italy.

On the grounds of recent geomorphological and structural studies (DI NIRO GIANO, 1995; GIANO et alii, 1997; 2000; SCHIATTARELLA et alii, 1998; CELLO et alli, 2000) the valley appears to be a more complex structure than an extensional graben or than a simple pull-apart basin as suggested by some authors. In any case, the last generation of lineations on fault planes documems an extensional regime with a NE-SW tensile axis. Such a tectonic restate persists until the present day, as inferred by the regional seismicity and in situ stress measurements (AMATO SELVAGGI, 1993; AMATO MONTONE, 1997) and as proved by, the occurrence of palaeosols affected by normal Faulting (GIANO et alii, 2000).
