The Lipari volcanic complex, situated in the central Aeolian sector, was constructed between c. 267 ka and medieval ages by various lava flows, scoriaceous deposits, lava domes (coulees) and pyroclastic products related to hydromagmatic and strombolian activities. The eruptive history of Lipari is described by nine Epochs of activity interrupted by dormant periods, volcano-tectonic phases and episodes of terrace formation during the Last Interglacial. Several partially overlapping volcanic edifices were active through time, mostly under control of the NNW–SSE and north–south (minor east–west) regional tectonic trends. The latest eruptive events of M. Pilato and Rocche Rosse occurred from AD 776 to 1220. Lipari rocks range from calc-alkaline basaltic andesites to rhyolites, with silicic rocks dominating during the last 43 ka. There is a clear increase in K2O and incompatible elements with time, with distinct trends for mafic-intermediate and silicic rocks. Sr, Nd and Pb isotope ratios are highly variable. Petrographic and geochemical data suggest AFC (assimilation plus fractional crystallization) and mixing as the main magma evolution processes, with important effects of crustal anatexis, in the context of a polybaric feeding system.
The 10 000 scale geological map of Lipari is included on the DVD in the printed book and can also be accessed online at http://www.geolsoc.org.uk/Memoir37-electronic. Also included is a full geochemical data set for Lipari.
Figures & Tables
The Aeolian Islands form one of the most active geological structures in the Mediterranean area, comprising a number of active (Stromboli and Vulcano) and dormant (Panarea and Lipari) volcanoes. They have attracted the attention of scientists in modern and historical times and are the cradle of the scientific discipline of volcanology.
This Memoir provides information on geological features of the Aeolian Islands volcanoes at a regional scale and for each island. The stratigraphy, structural evolution, eruptive and magmatic history of the Islands is presented, along with the geodynamic setting of the Aeolian volcanism and implications for magma origin and evolution processes. Particular focus is given to the active and dormant volcanoes and the related natural hazards.
It includes new 1:10 000-scale geological maps of the Aeolian Islands and bathymetric maps of sectors of the Aeolian archipelago, together with an extended dataset of rock compositions.
