    Description: The SEISMOFAULTS project (www.seismofaults.it) was set up in 2016 with the general plan of exploring the seismicity of marine areas using deep seafloor observatories. The activity of the first two years (Seismofaults 2017 and 2018) consisted of the installation of a geophysical-geochemical temporary monitoring network over the Ionian Sea floor. Eleven ocean-bottom seismometers with hydrophones (OBS/H) and two seafloor geochemical-geophysical multiparametric observatories were deployed to: (1) identify seismically active faults; (2) identify potential geochemical precursors of earthquakes; and (3) understand possible cause–effect relationships between earthquakes and submarine slides. Furthermore, five gravity cores were collected from the Ionian Sea bottom and ~4082 km of geophysical acquisition, including multibeam and single channel seismic reflection data, were acquired for a total of 4970 km2 high-resolution multibeam bathymetry. Using Niskin bottles, four water column samples were collected: two corresponding at the location of the two multiparametric observatories (i.e., along presumably-active fault zones), one corresponding at a recently discovered mud volcano, and one located above a presumably-active fault zone away from the other three sites. Preliminary results show: (1) a significant improvement in the quality and quantity of seismological records; (2) endogenous venting from presumably active faults; (3) active geofluid venting from a recently-discovered mud volcano; and (4) the correct use of most submarine devices. Preliminary results from the SEISMOFAULTS project show and confirm the potential of multidisciplinary marine studies, particularly in geologically active areas like southern Italy and the Mediterranean Sea.

    Description: Gases present in the Earth crust are important in various branches of human activities. Hydrocarbons are a significant energy resource, helium is applied in many high-tech instruments, and studies of crustal gas dynamics provide insight in the geodynamic processes and help monitor seismic and volcanic hazards. Quantitative analysis of methane and CO2 migration is important for climate change studies. Some of them are toxic (H2S, CO2, CO); radon is responsible for the major part of human radiation dose. The development of analytical techniques in gas geochemistry creates opportunities of applying this science in numerous fields. Noble gases, hydrocarbons, CO2, N2, H2, CO, and Hg vapor are measured by advanced methods in various environments and matrices including fluid inclusions. Following the “Geochemical Applications of Noble Gases”(2009), “Frontiers in Gas Geochemistry” (2013), and “Progress in the Application of Gas Geochemistry to Geothermal, Tectonic and Magmatic Studies” (2017) published as special issues of Chemical Geology and “Gas geochemistry: From conventional to unconventional domains” (2018) published as a special issue of Marine and Petroleum Geology, this volume continues the tradition of publishing papers reflecting the diversity in scope and application of gas geochemistry.

    Description: Le metodologie di indagine geochimica applicate ad un’ampia porzione dell’Appennino meridionale, esteso dalla Calabria settentrionale ai Monti Nebrodi, nell’ambito del progetto INGV-DPC S2, hanno consentito di valutare le caratteristiche dei fluidi emessi in coincidenza di importanti lineamenti strutturali, permettendo di evidenziare le relazioni intercorrenti tra l’assetto tettonico e la genesi, la circolazione ed il comportamento dei fluidi circolanti. L’area di studio rappresenta la porzione più meridionale dell’Arco Calabro, il cui stile deformativo dominante dal Pleistocene medio all’attuale, è caratterizzato da una estensione ESE-WNW. Nella Sicilia nord-orientale, le faglie neotettoniche dislocano i livelli crostali più superficiali e si dispongono secondo direzioni preferenziali orientati circa NW-SE con meccanismi deformativi a componente trascorrente ed estensionale e N-S/NE-SO con meccanismi deformativi trascorrenti, a tratti con componente compressiva. Le strutture crostali radicate sono rappresentate dal sistema “Patti-Eolie”, che si connette a terra con il sistema “Tindari-Letojanni” e dal “sistema di Messina”. Il primo mostra, anche a livello sismologico, caratteri deformativi transtensivi; nel secondo sistema, caratterizzato da faglie a prevalente componente distensiva del rigetto la catena presenta un tasso di sollevamento recente non uniforme, con valori massimi lungo la costa messinese ionica e tassi minori lungo quella tirrenica. L’esistenza di fenomeni attivi di sollevamento regionale è dimostrato da alcune evidenze, come la presenza di argille marine quaternarie affioranti diverse centinaia di metri al di sopra del livello del mare nonché di piattaforme di abrasione tirreniane ben sviluppate ad una altitudine di circa 130 m. nei pressi di Taormina e sul versante calabrese dello stretto di Messina. La struttura tettonica più importante che interseca il sistema Ibleo-Maltese è costituito dal sistema di faglie di Messina, orientato NNE-NNW. Il terremoto di Messina del 1908 è stato attribuito ad una “faglia cieca” nell’area di Messina. Lungo le principali strutture tettoniche, sono presenti attività idrotermali e di degassamento note da tempi storici, che dal punto di vista geochimico mostrano caratteristiche molto diverse in funzione della loro ubicazione.

    Description: The INGV and the Organizers are pleased to invite you to attend and contribute to the second International Workshop “Research in shallow marine and fresh water systems” taking place in Sicily, Aeolian Islands in October 2010 from the 3rd to the 10th. The workshop will provide the opportunity to meet scientists from different countries with different scientific skills to discuss and to exchange ideas on the scientific results related to the scientific diving activityScientific Diving as a tool “for the purpose” acquires a substantial need of an information exchange among research groups including scientific working methods in various fields of application: geology, chemistry, (micro-)biology, archaeology, geochemistry, environmental sciences, ecology, to name a few. The workshop will merge scientific communications with technical and scientific discussions besides diving excursions at selected sites of different scientific interest.

    Description: This paper aims to define the stability over the time of chemical elemental patterns in some citrus varieties of PGI (Protected Geographical Indication) and not PGI Interdonato and Lunario cultivars coming from Italy and Turkey and to set up a range of markers useful to trace their geographical origin. During the 2015–2017 growing seasons, all fruits were collected and subjected to Inductively Coupled Mass spectrom etry (ICP-MS) analysis, in order to determine the multielemental chemical profiles. The chemical variabil ity was calculated for each element by Multi-way analysis of variance. The results highlighted how the measured Cr, Ni, Al, K, Fe and Zn levels mainly depend on the soil composition and the fingerprint allow to trace the geographical origins. Moreover, the stepwise linear discriminant analysis (SLDA) has allowed to correctly classify the 100% of lemon pulps provenances, based on Ni, Al, K, Ca and Na con tents. Finally, our study demonstrates the role played by harvest years, variety and soils composition whose interaction contributed to define the chemical fingerprints.
