An Atlas of the Mediterranean Waterfronts: An Instrument for Knowledge and Direction
2016
In order to design the renewal for urban fluidity, the Atlas for Mediterranean Waterfronts is not only an instrument for knowledge, but it is the tool in which we can analyse the contemporary relation between nature and culture. The chapter explains the duality-based atlas that mirrors the condition in city-port urban management and it defines the structure of the Atlas that is founded on urban clusters identities as research field.
METAPHORS, HYRIDISATION AND SOCIAL SPACE
2018
Il contributo è il risultato dell'attività di ricerca condotta durante il workshop internazionale promosso dal Raffles Design Institute di Hong Kong e dall'Università di Palermo e organizzato con lo scopo di generare nuovi progetti nelle due città, evocando "nuove immagini per nuovi significati "e riconfigurando spazi e comunità. L'articolo descrive alcuni dei risultati del workshop partendo dal concetto delle metafore come giustapposizione di immagini apparentemente distanti, ma che, come risultato della stessa metafora, sono ricomposte in un'immagine diversa, carica di nuovi significati semantici. The contribution is the result of the research activity during an international workshop: th…
The Fluid City Paradigm : Waterfront Regeneration as an Urban Renewal Strategy
2016
This book presents a new paradigm of knowledge and action with respect to urban waterfronts and the “fluid city paradigm,” explaining its methodological framework and describing an integrated and creative planning approach in which waterfront regeneration is pursued as a key urban-renewal strategy. It focuses especially on the WATERFRONT project (“Water And Territorial policiEs for integRation oF multisectoRial develOpmeNT”), which was funded jointly by Italy and Malta with the goal of developing common guidelines, strategies, and operational tools for the planning of coastal areas, based on cross-border exchange of experiences. In the described approach, the waterfront is recognized as hav…

The structure of a hydrothermal system from an integrated geochemical, geophysical and geological approach: the Ischia Island case study
2011
The complexity of volcano-hosted hydrothermal systems is such that thorough characterisation requires extensive and interdisciplinary work. We use here an integrated multidisciplinary approach, combining geological investigations with hydrogeochemical and soil degassing prospecting, and resistivity surveys, to provide a comprehensive characterisation of the shallow structure of the south-western Ischia’s hydrothermal system. We show that the investigated area is characterised by a structural setting that, although very complex, can be schematised in three sectors, namely the extra caldera sector (ECS), caldera floor sector (CFS), and resurgent caldera sector (RCS). This contrasted structura…
Hydrothermal circulation on Ischia Island (Southern Italy), revealed by an integrated geochemical, geophysical and geological approach
2011
Volcano-hosted hydrothermal systems are complex geological objects, whose thorough characterisation requires extensive and interdisciplinary work. Indeed, even thought geological, geochemical and geophysical observations offer highly significant but independent information, only an integrated multidisciplinary approach can yield a comprehensive characterisation of the chemical/physical structure of hydrothermal systems. Notwithstanding the extensive application of geological, geochemical and geophysical techniques in geothermal research, there are only a few examples in the literature of concurrent use of the three techniques [Finizola et al., 2002; Zlotnicki et al., 2009]; these studies ov…
Petrology and geochemistry of peri-Mediterranean carbonatite magmatism: case studies from Fuerteventura (Canary Islands) and Mt. Vulture volcano (sou…
2023
Carbonatites are rare magmatic rocks of great scientific and economic importance, and carbonatite magmatism is mainly associated with intraplate continental tectonic settings, with some rare occurrences in oceanic contexts. Despite their importance, many aspects of carbonatite petrogenesis and evolution processes remain still poorly constrained. In order to further constrain the mantle source and the storage system of carbonatite magmas, Fuerteventura (Canary Islands) was taken as a representative case study of oceanic carbonatites, while Mt. Vulture (southern Italy) was taken as a representative case study of intra-continental carbonatites, with a two-fold aim: to understand (i) the role o…
Constraints on mantle source and interactions from He-Sr isotope variation in Italian Plio-Quaternary volcanism.
2008
[1] Helium isotope ratios of olivine and pyroxene phenocrysts from Plio-Quaternary volcanic rocks from southern Italy (seven Aeolian Islands, Mt. Vulture, Etna, Ustica, and Pantelleria) range from 2.3 to 7.1 Ra. Importantly, the phenocryst 3He/4He correlate well with whole rock Sr isotopic composition (0.70309– 0.70711), reflecting the mixing of two sources. A significant contribution of He from crustal contamination is recorded only occasionally (e.g., pyroxenes from Vulcano). When merged with data from the Roman Comagmatic Province, a remarkably strong near-linear He-Sr isotope correlation is apparent. The general northward decrease in 3He/4He corresponds to an increase in 87Sr/86Sr (and …
The heterogeneity of the Mexican lithospheric mantle: Clues from noble gas and CO2 isotopes in fluid inclusions
2022
The abundance of mantle-derived rocks and lavas, in combination with its tectonic evolution, render Mexico a perfect laboratory to investigate the chemical and the isotopic heterogeneity of the lithospheric mantle. New data on the composition of noble gases and CO2in Mexican mantle xenoliths and lavas is reported. Our samples consist of six ultramafic nodules from the Durango Volcanic Field (DVF) and the San Quintin Volcanic Field (SQVF), monogenetic complexes belonging to the Mexican Basin and Range province; and four lavas from the Sierra Chichinautzin (SCN), a Quaternary monogenetic volcanic field located in the Mexican volcanic arc. Ne and Ar isotopes in fluid inclusions reveal mixing b…
