Late Miocene shortening of the Northern Apennines back-arc

Belt-Parallel Shortening in the Northern Apennines and Seismotectonic Implications

“…Detailed accounts of the related debate can be found in [75] [76]. Here, we point out some issues about the Quaternary evolution of the study area that do not fit well the above interpretation.…”

HP-LT metamorphism in Elba Island: Implications for the geodynamic evolution of the inner Northern Apennines (Italy)

“…We conclude that high-P and low-T metamorphism affected the whole tectonic Kligfield, 1990;Carmignani et al, 1994;Jolivet et al, 1998;Brunet et al, 2000; 97 Rossetti et al, 2002;Molli, 2008;Brogi and Giorgetti, 2012). In early-middle Miocene 98 (Jolivet et al, 1990;Carmignani et al, 1995;Brunet et al, 2000;Bonini et al, 2014) 99 the tectonic regime changed and an eastward migrating extension affected the inner 100 Northern Apennines up to Present.…”

“…For this reason, Elba Island resulted a distinctive case with respect to the surrounding 72 areas, with fallouts on the supposed evolution of the Northern Tyrrhenian Basin 73 (Bonini et al, 2014).…”

“…6 indeed indicate that the Pliocene basin is delimited by southwestward dipping reverse faults, whereas these fault lines are not shown in the map. It is to be noted that these structures are Neogene in age (Bonini and Sani, 2002;Brogi et al, 2005;Brogi and Liotta, 2008;Bonini et al, 2014) and predate the Mt. Amiata volcanic edifice welling up.…”
