Ortona-Roccamonfina Line

The volcanoes of Emici and Roccamonfina occur on the Tyrrhenian side of the central Apennines, a sector of the Apennine orogen delimited by the Ancona-Anzio line in the north and by the Ortona-Roccamonfina line in the south (Locardi 1988). The pre-volcanic basement consists of various rock types belonging to distinct paleogeographic-structural units formed... [Pg.109]

Fig. 1.8. Magmatic provinces in Italy, as identified from major, trace element and isotopic characteristics of mafic rocks. The Ancona-Anzio, Ortona-Roccamonfina, 41° Parallel, Tindari-Letojanni-Malta and the Sangineto tectonic lines are also indicated. Inset distribution of volcanism with orogenic (i.e. high LILE/HFSE ratios) and anorogenic (i.e. low LILE/HFSE ratios) compositions. Arrows indicates migration of orogenic magmatism from Oligocene to present. See text for explanation. Fig. 1.8.
