Il Traforo stradale del Monte Bianco collega Entrèves, frazione di Courmayeur alla testata della Valle d’Aosta, con Chamonix e la Val de l’Arve, nel Dipartimento francese dell’Alta Savoia. Il tunnel è lungo 16,6 km e fu realizzato tra gli inizi del 1959 e il 14 agosto 1962, quando con l’ultima volata di mine fu abbattuto il diaframma che separava i...
Article
The Pancherot-Cime Bianche-Bettaforca (PCB) is an ophiolitefree decollement cover unit with a greenschist facies imprint, continental affinity and problematic provenance. It is located in the ophiolitic Piemonte zone which marks the suture in the north-western Alps of the Mesozoic Liguria-Piemonte ocean (western Tethys). A new stratigraphic reconst...
Article
For almost fifty years, the spirit and core values of the Italian Geological Society have been preserved with the help of a particular person: its historical General Secretary Achille Zuccari (1926-2015). In 2016, after long time, a general assembly of the scientific institution firstly took place without that bow-tie wearing gentleman and his inse...

The National Committee for Nuclear Research (CNRN) was established in 1952 and mainly supported by Felice Ippolito, to promote and develop Italian research in nuclear science and technology. The institution was later incorporated into CNEN (1960) and ENEA (1982). CNRN created the Frascati synchrotron and the nuclear research centers of Ispra in nor...
Article
The boundary between the Helvetic and the Penninic (= Briançonnais) Zones has long been recognized as a major fault (“Penninic Front”) in the Western Alps. A narrow oceanic domain has been postulated at least along part of this boundary (the Valaisan ocean). However, the information provided by the pre-Triassic basement has not been fully exploited...
Article
The continental crust involved in the Alpine orogeny was largely shaped by Paleozoic tectono-metamorphic and igneous events during oblique collision between Gondwana and Laurussia. In order to shed light on the pre-Alpine basement puzzle disrupted and reamalgamated during the Tethyan rifting and the Alpine orogeny, we provide sensitive high-resolut...

Several Permian gabbro bodies are known in the continental-derived Dent Blanche Tectonic System (Western Alps). A new gabbroic complex, the Berrio Gabbro, is described in this paper, and compared with the other gabbro bodies of the Adriatic palaeomargin, as well as of the Tsaté Unit, a remnant of the Piemonte–Liguria ocean, immediately underlying t...
Conference Paper
Full-text available
The Grand St Bernard-Briançonnais nappe system crops out along the arc of the Western Alps, as a first-rank component of the Austroalpine-Penninic collisional wedge. In spite of its blueschist- to greenschist-facies tectono-metamorphic reworking during the Alpine orogeny, significant relics of Permian, Variscan and older igneous and high-grade meta...
Article
The Roisan zone is a metamorphic cover unit exposed along the ductile shear zone between the Dent Blanche s.s. and Mont Mary-Cervino Upper Austroalpine outliers, Aosta Valley, north-western Italian Alps. It is characterized by the occurrence of dolostones, pure marbles, marbles with quartz, calcirudites and ophiolite-free calcschists. Locally, dolo...
Article
In 1922, Giorgio Dal Piaz, pupil, assistant and, from 1909, successor to Giovanni Omboni to the chair of geology in the University of Padova, wrote the monograph “L’Università di Padova e la Scuola Veneta nello sviluppo e nel progresso delle Scienze geologiche”. Now, almost a century later, I am inspired by this memoir, and wish to go back and revi...
Article
We present a 1:30,000 geological map resulting from detailed geostructural surveys carried out along the Italian segment of the design corridor for the Brenner Pass railway base tunnel (BBT), extending from Fortezza (Italy) to Innsbruck (Austria). The map covers the southern part of the Austroalpine-Penninic collisional wedge, the Periadriatic Faul...

Article
Magma-poor rifted margins are being increasingly recognized in present day Atlantic-type systems. However, findings of fossil areas floored by exhumed mantle or hyper-extended crust are comparatively rare within orogenic belts that were originated through the inversion of pre-existing rifted margins. This discrepancy may be due to the common reacti...

Le difficoltà alpinistiche non impediscono a Giordano di studiare le rocce “passo a passo nella loro naturale successione su più di 2500 m d’altezza verticale”, dal Breuil alla vetta, e di eseguire numerose misure altimetriche con un ingombrante barometro a mercurio. Queste parole, tratte dal resoconto della salita (Boll. C.A.I, 1868), indicano chi...

È raro nella storia dei 150 anni dell...
Article
This review is first and mainly an historical journey across two centuries of Alpine geology, from the early fixist views to the mobilist revolutions produced by the nappe theory and, later, by the global theory of plate tectonics, including the important developments of the last decade. This review is addressed to the Italian students and nonalpin...
Article
In order to improve the railway connection between Austria and Italy, a base tunnel, extending from Fortezza to Innsbruck (57 km), is under study. The design corridor crosscuts a large and strongly tectonized section of the Eastern Alpine chain, characterized by complex metamorphic and igneous lithology and polyphase structures developed under duct...

L'uomo moderno non sembra accorgersi, duran-te la frenetica vita quotidiana, di essere ancora profondamente radicato sulla Terra, a cui rivolge la dovuta attenzione solo in occasione di eventi catastrofici che lo riguardano in modo diretto, ma che poi dimentica rapidamente assieme alla lezione che potrebbe ricavarne. La geologia ha il privilegio di...

The Alps were developed from the Cretaceous onwards by subduction of a Mesozoic ocean and collision between the Adriatic (Austroalpine-Southalpine) and European (Penninic-Helvetic) continental margins. The Austroalpine-Penninic wedge is the core of the collisional belt, a fossil subduction complex which floats on the European lower plate. It consis...
Article
A large post-glacial deep-seated mass movement is described from the area east of Vipiteno-Sterzing (Alto Adige South Tyrol, Eastern Alps), mainly developed in calcschists of the ophiolitic Glockner nappe (southern antiform of SW-Tauern window). A close relationship exists between differential slope evolution, structural setting, and slope attitude...
Article
Two centuries of tectonic interpretations of the Alps are briefly reviewed, from the early fixistic tenets emphasizing vertical movements to the impact of the new global tectonics, through the epos of the nappe theory. From 1884 to the early 1900s, Alpine geology played a central role in the development of the nappe theory and modern tectonics. Mob...
Article
The Austroalpine Sesia-Lanzo inlier and upper Austroalpine Dent Blanche, Mt. Mary and Pillonet outliers occur on top of the western-Alpine orogenic wedge and, as a whole, override the structurally composite ophiolitic Piemonte zone. Instead, the Mt. Emilius, Glacier-Rafray, Etirol-Levaz and other lower Austroalpine eclogitic outliers are inserted w...
Article
Post-nappe brittle structures across the Austroalpine-Penninic wedge are representative of two principal deformation stages. The former (D1) developed during the Late Oligocene, the latter (D2) from the Miocene to the Present. Major D1 features are the E-W Aosta-Ranzola half-graben and the NE-SW Ospizio Sottile subvertical normal fault system. Olig...
Article
This paper reviews two centuries of geological work on the Monte Rosa massif, Western Alps, from de SAUSSURE's exploration and systematic mapping by GERLACH and the Italian Geological Service, to BEARTH's fundamental contribution, subsequent developments on surface to subsurface geology, and debated paleostructural restorations. The Monte Rosa mass...

Full-text available
Classic and alternative restorations of western Alpine Tethys are discussed, focusing on the Austroalpine-Piedmont groups of nappes and other alternances of continental and oceanic slices within the Penninic zone. The suggested reconstruction is consistent with the present sequence of nappes, the chronology of the Cretaceous-Eocene subduction, and...
Article
In the North Western sector of the Alps an intense brittle tectonics overprints the nappe stack and related ductile deformations. On a regional scale, different brittle structural sets can be identified. The main purpose of this work was to test the reliability of optical and SAR data to identify new lineaments and to test their mutual interference...
Article
A review of P-T peaks and paths of eo- and meso-Alpine eclogite fades rocks occurring along the axial part of the Alpine chain shows that rocks re-equilibrated under high- and low-T (group-B and -C eclogites), are, respectively, hosted within a lower and an upper tectonic level of the Penninic nappe system. If P-T estimates for eclogites are consid...
Article
In spite of the absence of ophiolitic slices at the surface, some traces of the lost Tethys ocean are recorded along the Pieniny Klippen Belt (PKB), a narrow décollement thrust system sutured at the transpressive boundary between the Outer and Inner Carpathians. The enigmatic precollisional evolution of Western Carpathians can be deciphered from so...
Article
The Alpine ophiolites are mostly concentrated in the inner and axial sectors of the Penninic nappe pile, as slices of the Jurassic Tethyan ocean which opened between the Europe and Adria (Africa) passive margins. The ophiolitic units consist of Mesozoic metasediments and mafic-ultramafic rocks, also including slices of subcontinental mantle. Metase...
Article
The oldest protoliths of the Austro-Alpine nappe system from the Western Alps consist of the intimate association of metapelites, tholeiitic metabasites and marbles which closely recalls the lithology and metamorphic evolution of the lower crustal section of the South-Alpine Ivrea-Verbano kinzigitic complex. This association may tentatively be inte...
