    New results of 40Ar/39Ar dating constrain the timing of transition from fissure-type to central volcanism at Mount Etna (Italy) (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: Recent geological studies performed at Etna allow reassessing the stratigraphic frame of the volcano where distinct evolutionary phases are defined. This stratigraphic reconstruction was chronologically constrained on the basis of a limited number of U–Th and K–Ar age determinations whose uncertainty margins are sometimes too wide. For this reason, we successfully adopted at Etna the 40Ar/39Ar technique that allowed obtaining more precise age determinations. The incremental heating technique also gives information on sample homogeneity, and potential problems of trapped argon. Five samples were collected from stratigraphically well-controlled volcanic units in order to chronologically define the transition between the fissure-type volcanism of the Timpe phase to the central volcanism of the Valle del Bove Centers. Isotopic ages with an uncertainty margin of 2–4% have been obtained emphasizing that this transition occurred (130– 126 ka) without significant temporal hiatus.

    Multiple hydro-fracturing by boron-rich fluids in the Late Miocene contact aureole of eastern Elba Island (Tuscany, Italy) (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: In eastern Elba Island (Tuscany, Italy), a shallow crustal level felsic, tourmaline-bearing, dyke-sill swarm of Late Miocene age is associated with abundant tourmaline-quartz hydrothermal veins and metasomatic masses. Development of these veins and masses in the host rocks demonstrates multiple hydro-fracturing by magmatic, boron-rich saline fluid. Tourmalines in felsic dykes are schorl, whereas in veins and metasomatic masses, tourmaline composition ranges from schorl-dravite through dravite to uvite. This compositional shift is evidence for an increasing contribution to the magmatic boron-rich fluids by a Mg-Ca-Ti-rich external component represented by biotite-rich and amphibolite host rocks. This system can be envisaged as an exposed proxy of the high temperature hydrothermal system presently active in the deepest part of the Larderello-Travale geothermal field (Tuscany).

    On the tracks of the ancient harbour of Tindari (NE Sicily) (2009)
    Université de Provence, conseil régional PACA, CNRS, TELEMME, CEREGE, Université Federico Due de Naples
    Details
    Publication Date: 2019-12-18
    Description: Historical sources testify to the flourishing maritime activity at the ancient town of Tindari, mentioning a harbour but not supplying information on its location, size or configuration. Because a town as important as Tindari must have had a landing place for ships, we examined new sources of information with the aim to localize traces of the harbour. Holocene uplifted and submerged notches, identified along the Tindari promontory, and the mooring iron rings, testify to past sea level changes. These elements are used to reconstruct the palaeotopography of Tindari Cape and the Oliveri coastal plain in the 4th century BC. The reconstruction reveals a safe landing place southeast of the Tindari Cape suitably protected from prevailing winds.
