Ancona-Anzio 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]

Formation of the Tyrrhenian Sea, and the associated counter-clockwise rotation of the Italian peninsula, resulted in longitudinal stretching of the Apennine chain and produced several arc sectors separated by important transverse tectonic lines. The main tectonic lineaments crossing the Apennine chain include the Ancona-Anzio line, the Ortona-Roccamonfma line,... [Pg.305]

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.
