    Sites of geo-cultural interest are often included in areas where multicultural contexts (geo and non geo) are present. Cultural heritage dissemination is sometimes mono-contextual, paying little attention to the possibility of inclusion in a wider multicultural context. When these different contexts are linkable to each other following a specific theme, multicultural heritage dissemination will be possible, and often the geo context can represent a fulcrum, a resilient tool in doing that. A portion of the Sinni river’s catchment area (Basilicata region, Southern Italy) has been chosen to test and verify the multi-level/disciplinary approach applicability. The area is located on the southeastern edge of the Pliocene to Pleistocene Sant’Arcangelo basin in the Southern Apennines chain of Italy. Here, both basic observations on the physical geography landscape evolution and specialized observations on river dynamics and on the hydrographic network have been carried out. Educational routes will be proposed with different educational levels along a path that will include the San Giorgio Lucano hypogea. This paper represents the results of a qualitative study providing an overview of the possibility, in a multicultural context, about whether, when, and how the geo context may act as a link between the different disciplines and what is the best way to make it. A relational database, organized in contexts, areas, and themes, is planned at different levels of detail, and is currently being developed in order to make final products easily available. Each level will be provided with basic concepts, territorial contextualization, and of activities/itineraries. The goal is to provide a versatile tool that enhances the territorial multi-cultural heritage to reach a greater number of end users interested in both geo and non geo contexts

    Geological and geophysical characterization of the Brindisi di Montagna Scalo landslide (Basilicata, Southern Italy)

    The Brindisi di Montagna Scalo Landslide in Southern Italy is an active complex mass movement, which affects the left slope of the Basento River. In the last few decades, this landslide has been continuously monitored, as it directly threatened some of the most important communication routes in the Basilicata Region. Nevertheless, little progresses have been made to prevent further landslide advancement, and continuous maintenance is required. With the aims of better understanding, the main factors controlling the evolution of this landslide, and suggesting the most appropriate countermeasures, a multidisciplinary study, based on the integration of direct and indirect techniques, was carried out. Direct techniques included multi-temporal geomorphological analysis of the slope, alongside geological and structural field observations. Indirect techniques consisted of electrical resistivity tomography acquisition. The combined analyses of the geological and geophysical data showed that Quaternary tectonic processes played a fundamental role as a predisposing factor, whereas seasonal rainfall, and the perpetual undercutting by erosional processes caused by the Basento River at the toe of the landslide are the main triggering mechanisms. The Brindisi di Montagna Scalo Landslide represents an outstanding case-study, concerning the interaction between a flow-like complex landslide and essential linear infrastructure, such as motorways and railways

    Geomorphological instability in the left slope of the river Basento involved in the huge Brindisi di Montagna ScaloLandslide (Potenza, Basilicata) ABSTRACT: The left slope of the river Basento valley near Brindisi di Montagna (PZ) railway station is characterized by the presence of diffuse geomorphological instability. There is a large complex landslide that from Tempa Pizzuta hill develops down to the base of the slope where river Basento flows and the Potenza-Metaponto railway and an important motorway occur. In the upper part the landslide has the form of a deep slide, that in the lower part of the hill becomes a large earthflow with retrogressive evolution. A detailed study of the stability condition of the whole left hand slope of river Basento valley has been carried out after the last reactivation of the earth-flow. On the base of a detailed geological and geomorphological survey it has been possible to define the relationships between the different geological formations outcropping in the area and to define the geomorphological evolution. In the area a complex superposition of tectonic units have, characterized by an eastward vergence, can be observed. The study, starting from the analysis of the geomorphological characters of the studied area, tried to explain the complex interaction between the slide in the upper part of the slope and the earth-flow at the bottom

    Reconstruction of tectonically disrupted carbonates through quantitative microfacies analyses: an example from the Middle Triassic of Southern Italy

    Get PDF
    AbstractThe main goal of the paper is the reconstruction of a Middle Triassic buildup cropping out in the central part of the Southern Apennines. Middle Triassic reefs of the western Tethys realm are well known in the Northern and Southern Alps. In contrast, few studies of the Anisian–Ladinian carbonate platforms of the southern Apennines are available, due to the diagenetic alteration and tectonic disruption that hinder their paleoenvironmental and stratigraphic reconstruction. In an attempt to fill this gap, and to improve the knowledge on the Anisian–Ladinian carbonates of central Mediterranean area, this research is focused on a carbonate buildup cropping out in the "La Cerchiara" area, Sasso di Castalda (Basilicata, Southern Italy). The buildup, affected by intense tectonic deformation associated with the development of the Apennine thrust and fold belt, was studied using a statistical evaluation of the quantitative microfacies data. The research enabled a reconstruction of the original stratigraphic relationships of the various buildup fragments. A positive linear regression between the sample positions vs the percentage of autochthonous carbonates indicates an increase of the autochthons carbonate toward the top of the succession. The allochthonous fabrics (packstone/wackestone) at the base of the section (Unit IIIa) pass gradually upward into autochthonous (boundstones) facies (Units IIIb, I), consisting of microbialites (clotted peloidal micrite, microbial-derived laminae, and aphanitic micrite), microproblematica and cyanobacterial crusts, with few encrusting skeletal organisms. Statistical data suggest that units IIIa, IIIb, and I are in stratigraphic order while unit II appears to have been moved by tectonic dislocation from its original position at the base of the succession. The absence of metazoan reef framework, and the richness of micro-encrusters, autochthonous micrite and synsedimentary cements, suggest a mud-mound style of growth for the carbonate bodies of the Southern Apennine during the Anisian

    Application of field surveys and multitemporal in-SAR interferometry analysis in the recognition of deep-seated gravitational slope deformation of an urban area of Southern Italy

    The analysis of 4 year In-SAR Interferometry images and a detailed geomorphological survey have been carried out to detect a large Deep-Seated Gravitational Slopes (DSGSD) affecting the urban area of the Episcopia village, in Southern Italy. The DSGSD largely develops within phyllites of the Liguride Units and, in the upper slope, within Pleistocene sand and conglomerate deposits of the Sant'Arcangelo Basin. Field survey has shown trenches at the top and an evident bulge at the base of the DSGSD, corresponding to the Talweg of the Sinni River. Geological and geomorphological field surveys allowed us to hypothesize a listric geometry of the DSGSD subsurface plane reaching about 700 m of depth. Furthermore, the multi-temporal In-SAR Interferometry analysis collected from November 2014 to May 2017 revealed that a ground deformation of ±30 mm was occurred, and the process is still active in the whole area

    BACKGROUND: Patients with atherosclerotic vascular disease remain at high risk for cardiovascular events despite effective statin-based treatment of low-density lipoprotein (LDL) cholesterol levels. The inhibition of cholesteryl ester transfer protein (CETP) by anacetrapib reduces LDL cholesterol levels and increases high-density lipoprotein (HDL) cholesterol levels. However, trials of other CETP inhibitors have shown neutral or adverse effects on cardiovascular outcomes. METHODS: We conducted a randomized, double-blind, placebo-controlled trial involving 30,449 adults with atherosclerotic vascular disease who were receiving intensive atorvastatin therapy and who had a mean LDL cholesterol level of 61 mg per deciliter (1.58 mmol per liter), a mean non-HDL cholesterol level of 92 mg per deciliter (2.38 mmol per liter), and a mean HDL cholesterol level of 40 mg per deciliter (1.03 mmol per liter). The patients were assigned to receive either 100 mg of anacetrapib once daily (15,225 patients) or matching placebo (15,224 patients). The primary outcome was the first major coronary event, a composite of coronary death, myocardial infarction, or coronary revascularization. RESULTS: During the median follow-up period of 4.1 years, the primary outcome occurred in significantly fewer patients in the anacetrapib group than in the placebo group (1640 of 15,225 patients [10.8%] vs. 1803 of 15,224 patients [11.8%]; rate ratio, 0.91; 95% confidence interval, 0.85 to 0.97; P=0.004). The relative difference in risk was similar across multiple prespecified subgroups. At the trial midpoint, the mean level of HDL cholesterol was higher by 43 mg per deciliter (1.12 mmol per liter) in the anacetrapib group than in the placebo group (a relative difference of 104%), and the mean level of non-HDL cholesterol was lower by 17 mg per deciliter (0.44 mmol per liter), a relative difference of -18%. There were no significant between-group differences in the risk of death, cancer, or other serious adverse events. CONCLUSIONS: Among patients with atherosclerotic vascular disease who were receiving intensive statin therapy, the use of anacetrapib resulted in a lower incidence of major coronary events than the use of placebo.

    Nell’ambito della Mostra Internazio- nale GEOFLUID, che si tiene ogni due anni a Piacenza, la SIGEA ha sempre avuto uno spazio riservato per orga- nizzare manifestazioni su tematiche geolo- gico-ambientali. Ad ottobre del 2014 è stato organizzato un convegno dal titolo: “Geologia e turismo: aspetti culturali ed economici”, un evento dedicato all’approfondimento di scenari di valorizzazione del patrimonio ge- ologico italiano nell’ambito del cosiddetto “giacimento turismo” del nostro Paese. Il turismo natura in Europa e in particola- re in Italia, è in continuo aumento, vi è quindi la necessità di pianificare azioni finalizzate ad intercettare questo flusso di turisti dando loro la possibilità di visitare i numerosi siti di interesse geologico, geomorfologico, geoar- cheologico, diffusi nel nostro territorio. Assieme al presidente della SIGEA, Giu- seppe Gisotti, hanno introdotto al convegno le testimonianze dirette degli esperti presenti al tavolo dei moderatori ed in particolare di Carlo Francou, direttore del vicino Museo Geologi- co di Castell’Arquato, e di Emaunele Emani, consigliere dell’Ordine dei geologi dell’Emi- lia Romagna. In tutti i casi è stata espressa la convergenza d’interessi verso l’attualità costituita dal “giacimento turismo” anche quale ambito occupazionale specialistico per le professioni correlate al geoturismo; ne sono state sottolineate anche i prestigiosi pa- trocini rilasciati dal Ministero dell’Ambiente (MATTM), da ISPRA, dalla Società Geologica Italiana (SGI) e dallo stesso Ordine Regionale dei Geologi. Alla manifestazione sono state presentate diverse relazioni, ricordate nella locandina di seguito riportata, che hanno suscitato gran- de interesse tra i presenti perché riguardanti esperienze di studio e di valorizzazione del patrimonio geologico in aree protette e non, con esempi di attività sviluppate in diverse parti del nostro Paese. Le relazioni hanno messo in evidenza le grandi opportunità legate al geoturismo e, contestualmente, le criticità che ne impedi- scono lo sviluppo, come la mancanza di una MARIO BENTIVENGA E-mail: [email protected] FABIO OLIVA E-mail: [email protected] normativa nazionale che favorisca le proposte di legge regionali definendone le linee guida e destinando loro risorse ad hoc. Particolare attenzione è stata rivolta an- che alla possibilità di sviluppo del turismo associato alla presenza di numerosi geoar- cheositi disseminati nel territorio italiano proponendo un modello di valorizzazione tu- ristico sostenibile. Pure significativa, infine, è stata la pre- sentazione di un’esperienza d’integrazione e comunicazione della conoscenza “geoturisti- ca” efficacemente realizzata attraverso i più moderni strumenti informativi e di navigazio- ne del territorio. Il convegno è certamente servito per far conoscere alcuni dei geositi del nostro Pae- se e per sensibilizzare gli amministratori del territorio affinché si avviino processi mirati alla loro valorizzazione e fruizione da parte dei turisti interessati, senza compromettere in nessun modo l’integrità dei luoghi
