    Description: During ODP Leg 107, the basement of the Tyrrhenian Sea was drilled at Site 650, located in the Marsili basin, and at Sites 651 and 655, both located in the Vavilov basin. In addition, a lava flow was drilled at Site 654 on the Sardinia rifted margin. Mineral and whole rock major and trace element chemistry, including rare earth element (REE) and Sr and Nd isotopic ratios, were determined in samples of these rocks. Site 654 lava was sampled within uppermost Pliocene postrift sediments. This lava is a basaltic andesite of intraplate affinity, and is analogous to some Plio-Pleistocene tholeiitic lavas from Sardinia. Site 650 basalts, drilled beneath 1.7-1.9-Ma-old basal sediment, are strongly altered and vesicular suggesting a rapid subsidence of the Marsili basin. Based on incompatible trace elements, these basalts show calc-alkaline affinity like some products of the Marsili Seamount and the Eolian arc. The basement of the two sites drilled within Vavilov basin shows contrasting petrologies. Site 655, located along the Gortani ridge in the western part of the basin, drilled a 116-m-thick sequence of basalt flows beneath 3.4-3.6-Ma-old basal sediments. These basalts are chemically relatively homogeneous and show affinity to transitional MORB. Four units consisting of slightly differentiated basaltic lavas, have been identified. Site 655 basalts are geochemically similar to the high Ti lavas from DSDP Leg 42, Site 373 (Vavilov Basin). The basement at Site 651, overlain by 40 m of metalliferous dolostone covered by fossiliferous sediments with an age of 2 Ma, consists of two basalt units separated by a dolerite-albitite intrusive body; serpentinized harzburgites were drilled for 30 m at the base of the hole. The two basalt units of Site 651 are distinct petrochemically, though both show incompatible elements affinity with high-K calc-alkaline/calc-alkaline magmas from Eolian arc. The cpx chemistry and high K/Na ratio of the lower unit lavas suggest a weak alkaline tendency of potassic lineage. Leg 107 basement rock data, together with data from DSDP Site 373 and from dredged samples, indicate that the deepest basins of the central Tyrrhenian Sea are underlain by a complex back-arc basin crust produced by magmas with incompatible element affinities to transitional MORB (Site 655 and DSDP Site 373), and to calc-alkaline and high-K calc-alkaline converging plate margin basalts (Sites 650 and 651). This petrogenetic complexity is in accordance with the back-arc setting of the Vavilov and Marsili basins. Other back-arc basin basalts, particularly those from ensialic basins such as the Bransfield Strait (Antarctica), show a comparable petrogenetic complexity (cf., Sounders and Tarney, 1984).

    Description: Scientific ontreach in the field of Natural Hazards, Seismology and Volcanology is one of the main activity ofIstituto Nazionale di Geofisica e Vulcanologia. A working group ofINGV scientists organize public events, publisll educational tools and documents for students and readers of ditTerent level and promote projects for schools. INGV Library network offers users services based on the dissemination of documents, data and information about earthquakes and volcanic eruptions. NAUTILUS is a pilot project promoted by INGV:

    Description: The Istituto Nazionale di Geofisica e Vulcanologia library network is composed by 8 libraries located in Milano, Bologna, Pisa, Roma, Napoli, Catania and Palerno and Porto Venere (SP). The main goal of INGV libraries was to suppod research activities tllfough the implementation of quality selvices and tools dedicated to researchers and to remote users. The libraries promote and develop electronic reSOllfces in the fields of geophysics and volcanology. One oftlle main project is: www.earth-prints.org. The intematioual opeu arcruve aims to satisfy the increasing demaud of fast, up-to-date, easyaccessible, and fi'ee-of-charge SOllfces of infonnationin all branches of Geosciences. It allows earth scientists to deposit electronic documents into its collections and to index them by subjects and keywords. Earth-prints provides a time-stamp to all deposited materials to insllfe precedence rights to original ideas and scientific results. It deals with copyright issues through Creative Common standards that offer a wide variety of licenses. All deposited material is made immediately available to the pUblic. Subscribers will be sent a daily newsletter according to the topics they have signed in. It The archive has a tllfee-Ievel hierarcrucal stmcture. The top level includes Atmosphere, CIyosphere, Hydrosphere, Solid Eatth and General. It then branches into several disciplines within the other two levels. Collections include different kinds of documents, such·as pre-prints, manuscripts, published papers, conference materials, books, book chapters, posters, theses, Web products and databases. Earth-Prints main language is English but it accepts also documents in other languages, giving visibility to data and studies at local scale that are indeed of general interests. An abstract in Englisll is always required. Have a tour in to the many features of Earth-prints.
