Marsili basin

The Aeolian archipelago is an active volcanic arc in the southern Tyrrhenian Sea (Keller 1982). It consists of several stratovolcanoes forming seven main islands and several seamounts, which extend to the west and northeast of the emergent portion of the arc, around the Marsili basin (Fig. 7.1). The volcanic activity exposed above the sea level took place entirely during the Quaternary, most probably from about 400 ka to the present (Gillot 1987). 

There are several seamounts located to the northwest (Sisifo, Enarete, Eolo) and to the northeast (Lametini, Alcione, Palinuro) of the Aeolian archipelago that define a horseshoe-type pattern around the Marsili basin. Ages range from 1.3 to less than 0.1 Ma. Compositions range from arc-tholeiitic (Lametini and southern Marsili basin), calc-alkaline and F1KCA (Marsili, Sisifo, Eolo, Panarea slope, Palinuro, Stromboli canyon and Alcione) to shoshonitic (Enarete, Eolo, Sisifo, and northern Stromboli slope). Description of rocks from Aeolian seamounts is given in Chap. 9.
