In order to study the freezing front characteristics of alpine tunnels under the condition of wind flow field and relying on the Osaka Mountain tunnel in Qinghai Province, the physical model test of an alpine tunnel was built. By using the Surfer software combined with the laboratory test data, the radial and longitudinal temperature variation trends of the tunnel were obtained, and the overall temperature vector graph of the tunnel was simulated; the radial and longitudinal evolutionary laws of a freezing front in an alpine tunnel under airflow conditions were systematically analyzed, and the radial and longitudinal governing equations of a freezing front in the tunnel model under airflow conditions were proposed. The results show that: With the decrease of the test air temperature, the thermonuclear area in the surrounding rock gradually shrinks, the frozen area of surrounding rock at the bottom of the arch gradually increases, and the frozen area of surrounding rock at the top of the arch gradually expands to the interior of the mountain. The influence degree of ventilation on the longitudinal and radial temperature distribution of the tunnel is obvious, and the greater the wind speed, the greater the influence degree. In particular, the fluctuation range of the longitudinal temperature distribution of the tunnel is more extensive under the influence of ventilation. The freezing front distance in the inverted arch area is the largest, and the expansion distance of the freezing front in the wall foot area is obviously higher than that in the vault; the variation of the longitudinal freezing front at different positions of the tunnel shows parabolic attenuation and with an increase in tunnel depth, the trend of freezing front gradually eases and becomes stable and disappears; the three radial regions of the freezing front and the longitudinal quadratic parabola governing equations can predict the specific distribution characteristics of the freezing front at different depths of the tunnel.

The present article concerns the problem of the contradiction between striving to maintain in the designed and implemented buildings of large volume in Polish area around the Tatras, in which it is justified to use current building technologies, including prefabricated buildings construction methods, and the need to continue the characteristic architectural forms of Tatra region. The demonstrated examples of architectural formation of buildings constructed during the interwar period-made for the needs of International Winter Olympics FIS, they used of the typical patterns of farms for the Alpine region. Such on example provides the evidence for the cultural pressure of a new function, i.e. skiing. Such an influence cannot be easily and consistently opposed in terms of logic performance of Tatra style current examples.

The Rupicaprini originated during the Miocene in Asia and dispersed during the late Miocene-early Pliocene, the Villafranchian, and the middle Pleistocene. Rupicapra and Oreamnos spread respectively to Europe and to North America in the middle Pleistocene. The Villafranchian Procamptoceras may be considered to be the closest known form to Rupicapra's ancestor. Rupicapra evolved during the middle and late Pleistocene in west Eurasia. At the beginning of the Würm glaciation the two closely related species R. pyrenaica and R. rupicapra were in existence. The former was already geographically split into Spanish-Pyrenean and central-southern Apennines groups, while the latter species ranged from the Caucasus to the Alpine Arch. R. pyrenaica shows more conservative features and possibly differentiated directly in western Europe from older representatives of the genus that migrated to western Europe in the middle Pleistocene. The cold-adapted Alpine chamois may have differentiated in eastern Europe and then migrated west-ward because of the advent of dry climates in the east Mediterranean and Pontic regions. The Alpine chamois failed to spread to the warmer southernmost regions of Europe that became a refugium area for R. pyrenaica. This dispersal hypothesis explains the morphologic, biometric, electrophoretic, and behavioral differences among modern chamois populations.

The european Alpine “stone arch” has its own natural and cultural identity. It represents “proto-architecture” that offers artistic inspiration, formal references, therapeutic effects. Slovenia and its Alps are small (like a fractal pattern of the big ones), but diverse in their landscapes, settlement culture and architectural traditions. Historically we were always part of Middle European cultural context (between the Alps, Mediteranean and Pannonian plains). Mostly part of bigger states, their culture reflected in built environment and architecture: from regulated order of the monarchy, the transition to modernity between WWI and WWII, “self-made” modernism of socialism, global capitalism free market trends after independance. The result is manifested in dispersed “urban sprawl” territories, a theme of “healing process” for younger urban planning and architectural generations to face with. Luckily less in the Alps with their strong traditions and topographies, where many compact historic settlements still witness their original urban matryx, (medieval) “spatial language” with its organic logic and very precise urban wisdom. Some extraordinary designers in Slovenia helped to create high level of architecture culture in XXth century (also in the alpine space): besides two great personalities, Maks Fabiani and Jože Plečnik, the latter started – together with Juan Vurnik – with “Ljubljana school of architecture”, there was also his follower Edvard Ravnikar (who worked also at Le Corbusier’s), who continued with the architecture. school and raised many good, modern architects. After the independence (1991) the younger generation reflects global trends, but also continues with architecture of high quality, found in some beautifull, diverse projects in the Alps. Today our alpine communites care more for their urban heritage and renew it, reurbanise their squares, streets and parks and support models of sustainable development, in which high level of building culture is an essential part of.

In the paper a model of the formation of the folded-covering-block structure of the Carpathians at a time interval that envelops Late-Hercynian and Alpine events is substantiated. Moreover, this concerns the Outer Carpathians, but the whole Carpathians arch was characterized without going into details, a critical estimate is expressed for application of such terms as terrains, accretion prism, suture, subduction and Transcarpathian fault. It is shown that formation of the Carpathians occurred through several stages under the influence of different-directed, manly horizontal, movements, as a result of which was destruction of early formed Hercynian continental crust, laying of geosynclinals troughs, formation and further transformation of the basement of the Flysch Carpathians, its collision with Eurasian continental edge, underling of the latter under flysh complex. After completion of these processes mainly vertical movements took place that lineally formed the structure of the Carpathians as folded-covering-block one. As a result of the last event (Pliocene-Pleistocene), a differential development of intensive fracturing occurred with the influx of hydrocarbons and filling traps formed up.

ABSTRACT The geological community has broadly accepted that the region of NE Africa and NW Arabia deformed under tension during the post-Hercynian disintegration of northern Gondwana. Further, it has also generally accepted that sedimentation occurred within extensional half-grabens that formed along the length of what was then the southern margin of the Neo-Tethys Ocean. Consensus is that Alpine age compression then forced inversion of these half-grabens to form the well-known Syrian Arc structures that stretch from the Western Desert of Egypt to NE Syria. As new data has become available (Enclosures I and II), there are indications that an alternative mechanism, founded in continuous compression rather than extension then compression, better explains the tectonics and sedimentary history of the region since the late Palaeozoic. Data from Syria, Jordan, the Levant and Egypt demonstrate that distinct post-Hercynian Orogeny, Tethyan and Alpine sequences (basins) lie on a final, deeply eroded and folded Hercynian Unconformity, and that this surface refolded post-Hercynian time to form the confining walls of a single trough extending from NE Syria to the Western Desert of Egypt. Prior to the deposition of the first Tethyan basin in the late Carboniferous, the Hercynian Unconformity surface deformed to establish a plate-scale arch, the Levant Arch, that extended from NE Syria and southern Turkey, over 1,500 km southwest to the three corners region of Egypt, Sudan and Libya. This arch refolded in the late Palaeozoic to form the early Levant Trough composed of the Palmyride Trough, its extension under the Eastern Mediterranean and the Levant, through the Sinai and into western Egypt. Contrary to the now established idea that the southern margin of the Carboniferous–Permian Tethyan Ocean was a “passive margin”, the trough and internally constrained basins, slowly narrowed and deepened under continuous compression from the southeast from at least the late Palaeozoic to the Present. Each internal, distinct basin sequence is well defined by long periods of slow, low-energy, laterally persistent, sedimentation, separated from underlying and overlying basin sequences by almost equally long periods of erosion or non-deposition, coincident with increased regional structuring and volcanism. Each new basin, following a cessation of this regional structural activity, found itself nested within its predecessor, with the older basin lying slightly counter-clockwise to the younger. It is proposed that counter-clockwise, regional (and basin) rotation was facilitated by newly documented NW-oriented cross-shears, with inter-basin periods of erosion or non-deposition due to whole-basin (regional) uplift, forced by trough narrowing. Tectonic-scale geologic features, such as cross-basin and regional shears, trough margin uplift and northwest migration, laterally extensive, sheet-like sedimentation, sediment feathering onto unfaulted margins, regional erosion related to whole-basin uplift and massive flank gravity sliding with resultant down-slope buckle folding, taken together, attest to compression as the driving agent. Whole-basin and regional, counter-clockwise rotation through time, suggests a constant direction of compression. Understanding the correlation of sedimentary fill to local and regional structural events brings new insight to the deformation of the northern regions of Gondwana during the closure of Tethyan oceans. This model may also apply on a larger scale of whole-plate deformation.

In order to understand the process of neolithisation of Southeastern and Central Europe, must be underlined the important role played by Transylvania through the numerous springs and salt lakes. The whole Carpathian arch of Transylvania is surrounded by impressive salt sources (Map 1). After a cold period in Europe between 6300-6100 BC, around 6000 BC there is a heating that corresponds to Greece and Anatolia with very hot and dry periods, which causes small pastoral communities to migrate from the Greek-Macedonian areas to the north. These first shepherds’ communities with sheep flocks, defined with a general term, as Early Neolithic, migrate northwards and sit in salt areas. In the Carpatho-Danubian Basin, this civilization is defined by archaeologists with the term Starčevo-Criş culture. The first horizon was defined as Monocrom- Frühkeramik and Starčevo-Criş IA respectively (shortly SC). Very soon, finding out the beneficial conditions (pastures, forests, mountains with alpine pastures, but especially salty springs), other communities with large cattle come, laying the foundations of some important Early Neolithic sites in Transylvania: Cristian, Ocna Sibiului, Miercurea Sibiului, Gura Baciului and those in Apahida – Cojocna zone. Migration after migration and diffusion sought and used salt sources which together with the environmental factor (pastures, forests, and alpine meadows) contributed to the neolithisation process. In SE Transylvania, Moldova, central and north Crişana neolithisation process starts only with the evolved phases of the Starčevo-Criş culture. The most interesting and important discoveries related with the end of Early Neolithic are those of Lunca – Poiana Slatinii (Neamţ County). The salt roll for the neolithisation processes of N Hungary, Slovakia (Hurbanovo and Biňa, Košice-Červeny Rak a.s.o.) and E Austria (Prellenkirche a.s.o.) is related with the evolved phases of SC culture (Zăuan, Tăşnad – Sere). Neolithic sites located in area of salt sources of Someş and Tisa basins prove also ethno-cultural exchanges (obsidian import of NE Hungary, SW Slovakia and maybe other).

L'Arc en Maurienne (Savoie) présente à l'état naturel tous les caractères d'une rivière torrentielle à forte pente, à l'hydrologie contrastée, aux transports solides abondants. Depuis le XIX siècle, des interventions anthropiques massives ont transformé profondément le fonctionnement du système fluvial : un endiguement insubmersible sur les deux tiers du cours d'eau, l'assainissement de la basse vallée par colmatage et drainage, des travaux de correction torrentielle dans les bassins versants affluents, le développement des équipements hydroélectriques. Maîtrisé, l'Arc est à l'origine de la transformation de l'espace mauriennais en couloir industriel. Les aménagements de la rivière entraînent des perturbations profondes de l'hydrologie : la modification des débits et des rythmes des écoulements ordinaires, la suppression des crues de forte fréquence et la création d'un régime-usine artificiel. Le domaine dans lequel l'anthropisation est la plus caractéristique et la plus lourde de conséquences en terme de gestion est celui de la morphologie fluviale. Le transit des matières en suspension n'est plus entièrement assuré ; la charge de fond, pour l'essentiel d'origine torrentielle, continue de parvenir dans le talweg tandis que l'affaiblissement de la puissance de la rivière a supprimé sa capacité d'évacuation. La tendance à l'exhaussement et à l'engorgement du lit constitue un trait original dans l'évolution actuelle des rivières alpines. Dans ce contexte, les grandes crues, non modifiées par les équipements hydroélectriques, deviennent des épisodes paroxysmaux dont les effets sont amplifiés. Le cumul des perturbations anthropiques conduit à l'élaboration d'une dynamique fluviale d'un type nouveau, artificielle et tronçonnée.

A partir de nouvelles observations structurales, nous proposons un nouveau modèle cinématique pour la Zone Houillère Briançonnaise, située au-dessus du front briançonnais (structure majeure des Alpes occidentales). Ce modèle est conforté par l'inversion des données de déformation finie, interpolées et visualisées à l'aide du modeleur 3D GOCAD (ENSG-LIAD Nancy). Les données de déformation finie ont été acquises par l'utilisation d'algorithmes d'analyse d'images, semi-automatisées au cours de ce travail. L'inversion a été effectuée à l'aide du logiciel FaultPack (Université Rennes 1). Le modèle cinématique qui résulte de ce travail se décompose en trois évènements principaux suivis d'un épisode extensif. L'évènement D1 traduit très probablement la subduction de l'océan piémontais au cours de laquelle, restant dans le prisme d'accrétion tectonique, la Zone Houillère subit un écaillage vers L'ouest alors qu'une partie de la Vanoise est entrainée dans la subduction. Au cours de D2, la subduction de la Vanoise se bloque et cette zone est alors charriée sur la Zone Houillère puis elle l'emboutit. L'évènement D3 est associé à l'indentation de la croûte européenne par le poinçon adriatique. Cette indentation est, entre autre, la cause de la surrection des Massifs cristallins externes qui réactive une surface correspondant au Front Briançonnais originel (décollement précoce D1 et/ou structure D2) en faille normale. Le rebroussement résultant de la surrection des Massifs cristallins externes produit une structure de type roll-over. L'évènement extensif D4, continuum plus superficiel de D3, provoque alors le basculement de tout l'édifice vers l'Ouest

Située à l'extrême-ouest de la Méditerranée occidentale, la chaîne bético-rifaine s’est formée au travers d’une histoire orogénique alpine complexe, impliquant des processus de subduction liés à la convergence entre l’Afrique et l’Eurasie depuis le Crétacé. Une découverte importante de ces quatre dernières décennies d'investigations géologiques, a été la mise en évidence des vestiges d’un événement varisque dans les zones internes de la chaîne. Ces résultats soulignent bien la présence de deux systèmes orogéniques superposés, les zones internes de la chaîne bético-rifaine demeurent donc des zones privilégiées pour étudier l’importance de l’héritage structural et métamorphique dans les réactivations partielles ou totale par les évènements les plus récents. Ce travail est localisé dans le secteur de Beni Bousera, ou affleurent les roches crustales et mantéliques qui forment les unités les plus internes de la chaîne. Il s’appuie sur une étude menée à partir des analyses structurales et pétrologiques, des datations U-Th-Pb sur monazite et 40Ar-39Ar sur des micas et des amphiboles. Il nous permet de résumer l’histoire de la chaîne bético-rifaine de la manière suivante : 1) un événement de HP-HT affecte la base du domaine interne à ca 281 ± 3 Ma. Ces nouvelles données pétrologiques et géochronologiques obtenues dans le Rif interne sont corrélées avec les Bétiques, les Kabylies et le massif de l'Edough en Algérie, la ceinture mauritanienne et les Appalaches. Elles attestent d'un domaine convergent au cours du Carbonifère supérieur- Permien inférieur. Tous ces segments orogéniques font partie des Variscides nord-africains construits à la marge nord-ouest du Gondwana en réponse à une convergence entre cette dernière et la Laurentia. 2) autour de 29-26 Ma, un événement métamorphique avec un gradient de type Barrovien à Abukuma affecte les Sebtides (les unités les plus internes de la chaîne), et il est interprété comme résultant de l'évolution de la plaque supérieure d'une zone de subduction. Cet évènement alpin est caractérisé par un chemin prograde marqué par un réchauffement à la base des Sebtides entre 26 et 22 Ma. De telles conditions reflètent un amincissement et un réchauffement de la croûte liée à la remontée asthénosphérique due au retrait de la plaque plongeante ; cet événement marque le début d’un évènement extensif majeur. 3) Au Miocène inférieur à 22-20 Ma, les zones internes (ou domaine d’Alboran) sont affectées par une extension E-W contemporaine de l’ouverture du bassin d'Alboran dans un contexte arrière-arc, et par l’intrusion de filons granitiques dans les péridotites et les unités métamorphiques crustales du domaine interne. Cet évènement a permis l’exhumation finale des Sebtides. 4) Du Miocène inférieur au Miocène moyen, la chaîne bético-rifaine a acquis sa géométrie arquée (l’arc de Gibraltar) suite à la collision entre les zones internes et les zones externes, attestée par une phase de raccourcissement majeur de direction NE-SW à E-W, et 5) l’arc de Gibraltar est affecté par une phase de raccourcissement N-S ante-Pliocène de direction N-S, qui a modifié considérablement sa géométrieLocated at the extreme tip of the western Mediterranean, the Betic-Rif orogenic system is built through a complex alpine orogenic history involving processes of subduction related to convergence between Africa and Eurasia since the Cretaceous. A remarkable discovery during the last four decades of geological investigations, has been the remains of a variscan event in the internal zones of the belt. These results underline the presence of two superimposed orogenic systems, the internal zones of the belt thus remain a privileged area to study the importance of the structural and the metamorphic heritage in the partial or total reactivation by the most recent events. This work is located in the Beni Bousera sector, where crustal and mantle rocks that form the innermost units of the chain are exposed. Based on structural and petrological analyses, U-Th-Pb dating on monazite and 40Ar-39Ar dating on micas and amphiboles. The history of the Betic-Rif belt can be summarized as it follows: 1) a HP-HT event affects the base of the internal domain at around 281 ± 3 Ma. These new petrological and geochronological data obtained in the internal Rif, are correlated with the Betics, the Kabyle, the Edough massif of Algeria, the Mauritanian, and the Appalachian belts, attesting a convergent domain during the late Carboniferous – early Permian. All of these orogenic segments are part of the North African Variscides built at the north-western margin of Gondwana in response to convergence between the later and Laurentia. 2) at around 29-26 Ma, a Barrovian to Abukuma metamorphic event affects the Sebtides (the innermost units of the chain) and interpreted as the evolution of the upper plate of a subduction zone. This alpine event is typically characterized by a prograde metamorphic path marked by heating affecting the base of the Sebtides between 26 to 22 Ma, such conditions reflect thinning and heating of the crust related to the asthenosphere upwelling due to slab roll-back. This event marks the beginning of a major extensive event. 3) In the Miocene around 22-20 Ma, the internal zones are affected by an E-W extension contemporary to the opening of the Alboran Basin in a back-arc context, and the intrusion of granitic dykes into the peridotites and crustal metamorphic units, the exhumation of the Sebtides was complete at this time. 4) From early to middle Miocène, the Betic-Rif belt acquired its arcuate geometry (the Gibraltar Arc) during the collision between the Internal and the external zones, attested by de NE-SW to E-W shortening phases across the arc. 5) more lately prior to Pliocene, the Gibraltar arc was subjected to contractional possess related to a N-S shortening phase, which drastically altered its geometry

Etudier les dynamiques et enjeux au sein d’un village de montagne, en Savoie, engendre une réflexion plus générale sur des questionnements importants de l’époque contemporaine. Jean-Marc Villermet a choisi d’aborder ce sujet pour plusieurs raisons : son attachement à cette région, la proximité des archives, le désir de réactiver le chantier de l’aménagement du territoire en altitude.Il s’intéressa à une région désertée, bien que située dans un espace montagnard réputé pour la qualité de ses sites dans une dimension internationale. Jamais la transformation et les mutations économiques et sociales des zones montagnardes en difficulté, souvent qualifiées d’immobiles, n’ont véritablement été étudiées pour elles-mêmes sous cet angle. Cela semblait donc une piste à la fois nouvelle et tout à fait digne d’intérêt ; d’autant que, situé en Maurienne, le territoire sur lequel se pencha l’auteur demeure aujourd’hui marginal, à l’écart des grands flux touristiques.Ainsi, à partir des années 1860, période où la Savoie devint française jusqu’aux mutations du XXIe siècle, Jean-Marc Villermet a voulu montrer toute la relativité des concepts classiques, voire datés, d’immobilisme ou d’archaïsme, y compris pour un espace montagnard « en souffrance ». Il en étudia les métamorphoses dans toute leur complexité.Cette analyse fine vise à comprendre comment les processus économiques et sociaux ont été portés, vécus et perçus par les individus et comment ils se sont manifestés dans l’espace. Le terrain choisi, l’espace Grand Arc - Lauzière, identifié par le village de Montsapey, dans le canton d’Aiguebelle, sur la rive droite de l’Arc, répond aux critères recherchés : ceux d’une région d’altitude traversée par la déprise rurale depuis un siècle, relativement isolée, bordée en amont et en aval par d’autres territoires beaucoup plus dynamiques.La démarche adoptée se situe au carrefour de plusieurs écoles historiques. Se référant au changement dans sa globalité, ce travail se nourrit des enseignements des grandes thèses classiques d’histoire relatives aux mutations économiques et sociales. Par ailleurs, se réclamant de la micro histoire, l’auteur en utilise les apports et les éclairages.Les sources exploitées proviennent du dépôt des archives départementales de la Savoie et des archives communales sur le territoire étudié. Celles-ci sont confrontées aux documents émanant de différents centres d’archives à Paris. La presse nationale et régionale apporte des éclairages intéressants. Un important travail de collecte d’archives privées a également été effectué, complété par la réalisation de nombreux entretiens et d’un abondant recours à l’iconographie.Proposée dans la première partie de la thèse, l’analyse d’un territoire montagnard a priori fermé, mais en réalité ouvert sur le monde, s’avère riche d’enseignements. Jean-Marc Villermet s’est attaché à démontrer l’importance des mouvements de population en montagne dans une dimension nationale et internationale ; la circulation des hommes et des idées. Il s’agit d’évaluer les conséquences des mouvements migratoires sur l’aménagement du territoire. Les permanences et les « archaïsmes » qui perdurèrent furent accompagnés de regards neufs portés sur la montagne lorsque les hommes explorent les formes, franchissent les reliefs par la voie aérienne et souterraine ou extraient des richesses minérales.La deuxième partie est consacrée aux inéluctables tensions qui perdurèrent pour aménager le territoire : entre offre et demande de montagne. Après la Seconde Guerre mondiale, à l’heure de l’essor des stations de sports d’hiver dans les Alpes, soixante-dix ans de projections permirent d’élaborer des stratégies variées pour dynamiser la pente aux portes de la Maurienne. Des activités économiques pérennes furent envisagées même si elles laissèrent peu de traces durablement. La montagne constitue-t-elle alors un espace de conquête ou d’abandon ? Il y a peut-être de nouveaux concepts à imaginerAnalysing spatial dynamics and major issues in a mountain village needs to carry out a general review. Jean-Marc Villermet has chosen to study this subject for many reasons : his attachment to the area, public records going back to centuries, and a desire to promote land-use planning at high altitude.His interrest to an abandoned area, even though part of a famous wild space, is consistent with an international focus. All economic, technical and societal developments forcing mentalities and practices to change, have not yet been studied or evaluated from this perspective in moutain areas in trouble, often qualified as unmovable. This clearly is an interesting new lead to follow up on, in at much this area studied by the author remains marginal, out of the major tourism flows.In this way, from the 1860s, date of the french Savoy period, to the beginning of the XXIst century, Jean-Marc Villermet wishes to demonstrate a significant impact on relativity of conventional concepts challenging the status quo, absolute inaction, archaic procedures concerning this remaining action mountain area. The transformation must be assessed with a thorough understanding of this complexity.The narrow consideration of territories also aims to discover the economic and social process implemented, experienced and seen by different groups in society and how they occupied the territorial space. This area, Grand-Arc-Lauziere mountain, identified by Montsapey, a balcony nestled on the Arc river valley, meets the search criteria : a high-altitude isolated land subjected to an over century-long rural decline, impacted upstream and downstream by much more dynamic territories.The approach adopted is at the crossroads of historical trends. Refering to a global change, this study capitalizes on the experience and knowledge that has been accumulated under many PhDs in economic and social history. Availling himself of the micro-history, the author uses its benefits shedding light on the matter.Sources come from records filed with the local and departmental archives, faced with national archives in Paris. The national and regional daily newspapers bring a different approach. A substancial data collection was performed, supplemented with additional interviews and images.As suggested in the first part of the study, analysing major issues in a mountain village, both a closed territory and a land opened up to the World, offers a detailed and insightful account of history. Jean-Marc Villermet is committed to show the huge population swift towards cities with a national and international perspective, movements of people and flows of information. This study evaluates how migratory flows affect land-use planning. Archaic conditions and outdated practices were accompagnied by new perspectives, when people explored the mountains from the air or tunnels and underpasses, to extract mineral resources.The second part is dedicated to the ineluctable tensions that continued : the balance of supply and demand and changes in patterns of mountain request. After World War II, at a time where ski resorts were built in the French Alps, during seventy years, many essential coordinated strategies were prepared to stimulate sustainable, long-term and effective activities on the slope of the mountains around Montsapey. Today, does it reflect the values of a community on a conquered territory or a derelicted place ? An original creative effective concept has to be imagined for the future

The study of the objects LaTène type found in middle-eastern alpine region (Trentino Alto Adige-Südtirol, Engadina, North Tirol, Voralberg and Villach basin) is aimed to a better comprehension of the complex net of relationships established among the Celts, settled both in the central Europe territories and, since the IV century b.C., in the Po Plain, and the local populations.
The ancient authors, who called the inhabitants of this area Raeti, propose for this territory the usual pattern according to which, the population of a region was formed consequently to a migration or was caused by the hunting of pre-existing peoples.
The archaeologists, in the last thirty years, recognized a cultural facies typical of the middle-eastern alpine territory during the second Iron Age, and defined that as Fritzens-Sanzeno culture (from the sites of Fritzens, Inn valley, and Sanzeno, Non Valley). The so-called Fritzens-Sanzeno culture spread out without breaks from the material culture of the final Bronze Age and the first Iron Age.
This local substratum, characterized by a ceramic repertoire strongly standardized, by peculiar architectural solutions and by a particular typology of rural sacred places (Brandopferplätze), accepted, above all during the second Iron Age, the strong influences coming from the Etruscan world and from the Celtic one (evident in the presence of objects of ornament, of glass artefacts, of elements of the weaponry and of coins).
The objects LaTène type become, with different degrees of reliability, important markers of the relationships existing between the Celts and the Raeti, although the ways of interaction (cultural influence, people's movements, commercial exchanges, gifts among élites etc.) is not still clear.
The revision of published data and the study of unpublished materials allows to define a rich and articulated picture both to chronological level and to territorial one.

Cette thèse cible l'évolution Néogène de la branche sud de l'arc alpin occidental. Une approche multi-méthodes associant études de terrain, sismotectonique et thermochronologie basse température y met en évidence un régime tectonique complexe ainsi qu'une évolution morphologique et structurale originale au sein de l'arc. La fracturation s'organise autour d'un faisceau d'accidents NW-SE, à jeu principalement dextre, accompagnant la courbure de l'arc et commandant structure et morphologie. Par ailleurs, à l'échelle des massifs, une structuration en failles normales conjuguées NE-SW traduit une extension parallèle à la chaîne. D'autres failles normales traduisent une extension perpendiculaire à la chaîne. L'inversion des données microtectoniques a permis de caractériser des régimes de paléocontraintes décrochant et extensif. L'absence d'une chronologie cohérente à l'échelle régionale suggère que ces régimes ont coexisté. Je propose que ces régimes constituent deux extrêmes d'un régime de contrainte unique variable, résultant de l'interférence entre un champ de contraintes extensif, à tendance multidirectionnelle et propre à la partie interne, surépaissie de la chaîne, et un champ de contraintes décrochant à transpressif commandé aux limites de la chaîne. L'analyse sismologique montre que l'arc interne subit actuellement un régime transtensif en zone Briançonnaise et un régime purement extensif en Zone Piémontaise, plus interne. La direction d'extension reste proche d'E-W, comme plus au nord à la latitude du Pelvoux, et indépendante de la courbure de l'arc. La caractérisation du régime extensif actuel en termes de directions tangentes ou radiales à l'arc est donc ici inadaptée. La Zone Externe présente un régime globalement transpressif à nuancer puisqu'elle est également affectée par de l'extension dans sa partie la plus interne. Je propose une corrélation entre la zone subissant l'extension et la zone d'épaisseur crustale maximum. Ce modèle s'inspire et étend celui proposé par [Delacou et al., 2004]. Il favorise un processus d'extension lié à un effondrement gravitaire de la chaîne. La structure arquée concerne surtout la croûte supérieure, les structures plus profondes étant plus linéaires. Ce découplage vertical des structures est probablement hérité du poinçonnement syncollision oligocène, responsable de la formation de l'arc interne. Il peut expliquer qu'au Néogène le découplage tectonique entre arc interne en extension et zone externe en transpression ne réactive pas, près de la surface, l'ancien front chevauchant de l'arc interne, comme c'est le cas plus au nord au sein de l'arc. Quelques nouvelles données thermochronologiques (traces de fission dans l'apatite), replacées dans une synthèse des données existantes, confirment que les Alpes sud-occidentales ont connu une évolution structurale et morphologique originale au Néogène. Les zones internes présentent un refroidissement final homogène et rapide dès la fin de l'Oligocène. Le saut d'âge entre zone externe et zones internes, récemment mis en évidence à la latitude du Pelvoux, est confirmé dans l'ensemble de la branche sud de l'arc. Il témoigne de l'inversion du front chevauchant des zones internes peu de temps après le paroxysme de la collision. Je relie l'exhumation rapide des zones internes de la branche sud à la forte érosion d'une cordillère alpine axée sur les zones internes au front du poinçon apulien. La quantification de l'évolution du relief à partir du système traces de fission sur Apatite a été testée sur la base de deux transects échantillonnés dans les massifs du Pelvoux et Dora-Maira. Les relations âges-altitudes à différentes longueurs d'onde permettent d'estimer un taux d'exhumation moyen de 0.4km/Ma pour le Pelvoux au cours des 7 derniers Ma, et de 0.1Km/Ma pour Dora-Maira au cours des 20 derniers Ma. Pour ces deux massifs, aucune évolution probante du relief n'est mise en évidence. On souligne dès lors le manque de résolution du système apatite pour quantifier l'évolution du relief. Une synthèse des résultats permet de proposer que la déformation soit le résultat d'un équilibre instable entre l'étalement de la chaîne sous l'effet des forces de volume et la cinématique complexe de l'Apulie qui intègre à la fois une composante en translation et une composante rotationnelle.

Famous for the late 14th-century revolt known as Tuchinaggio, the Canavese area, in north-western Piedmont, provides significant information concerning the relationship between lords and subjects in a longer time span. By analysing a wide range of sources (pastoral visitations, chronicles, court and notarial records, statutes), the essay examines the domini-homines dialectic in the first half of the 14th century: in the Canavese Alpine valleys various degrees of institutional consolidation of communities can be outlined, identifying a process of growth common to communities in the entire Alpine Arc.

The present-day major relief features of western Europe are to a great extent determined by the underlying geological structures, either passively or actively. To get a comprehensive picture of their morphological evolution and interrelations, this chapter provides an overview of the spatial and temporal characteristics of the larg-escale tectonic framework of the continent. After having described the west European landscape at the end of the Palaeozoic, to which time the oldest preserved landforms date back, an outline of the Mesozoic and Cenozoic history of the major tectonic domains follows. Finally, some denudation estimates highlighting the relationship between tectonics, erosion, and the resulting relief, will be discussed. The three main influences on the present-day topographic patterns are those of the Alpine orogeny, the Cenozoic West European rifting, and the imprint of Variscan structures. They combine within a regional stress field determined by the Africa–Eurasia collision and the Alpine push as well as the mid-Atlantic ridge push. Since the end of the Miocene, this stress field is characterized by a fan-shaped distribution of SHmax along the northern border of the Alpine arc. This gives way to a more consistent NW–SE to NNW–SSE direction of compression further from the chain (Bergerat 1987; Müller et al. 1992). Topographically, western Europe may be roughly divided into a series of belts parallel to the Alpine chain. The Alpine chain culminates in a number of peaks exceeding 4,000 m in elevation (4,810 m at Mont Blanc) but the average altitude is in the order of 2,000 m. To the north, the mountainous Alps are bordered by the Molasse foredeep basin whose surface makes an inclined plane descending northwards from c.1,000 m to c.300 m near the Donau River in the Regensburg-Passau area. To the north-west, the Molasse basin narrows between the Alps and the Jura Mountains and is occupied by several extended lakes inherited from Quaternary glacial activity. Next to the Molasse basin in the north and west is a wide belt of recently more or less uplifted areas between 200 and 1,000 m in elevation (and locally in excess of 1,000 m in the French Massif Central and the Bohemian massif).

ABSTRACT The Cenozoic accretionary complex in the Calabrian Arc, southern Italy, contains hectometric- to kilometric-scale exposures of basalt, gabbro, and serpentinite that have been interpreted as dismembered fragments of Alpine Tethys ocean crust because of their incomplete nature with respect to the traditional view of a complete ophiolite sequence. We present new geologic mapping, geochemistry, and geochronology of one of these units at Timpa di Pietrasasso near the town of Terranova di Pollino in the Basilicata region that exposes Jurassic Tethyan pillow basalt and chert that are separated from gabbro and serpentinite by a fault. The gabbro in the footwall is Permian in age, indicated by U-Pb zircon ages of 284 ± 6 Ma, 293 ± 6 Ma, and 295 ± 4 Ma, linking it to gabbros that underplated continental crust after the Permo-Carboniferous Variscan Orogeny. The gabbro first underwent amphibolite-facies metamorphism, then developed a greenschist-facies mylonitic foliation near the fault surface that is crosscut by undeformed Jurassic-aged dikes of Tethyan origin, indicating that deformation is early Tethyan or pre-Tethyan in age. The underlying serpentinite is tectonically interleaved with blocks of Variscan lower crust, indicating that the missing upper plate of the extensional detachment complex was continental in origin. These features indicate that the Timpa di Pietrasasso unit preserves a low-angle detachment fault that developed in a hyperextended continental margin of the Alpine Tethys.

ABSTRACT Two contrasting field relationships may reflect different tectonic settings of subduction initiation preserved in orogenic belts. “Hot” subduction initiation assemblages include a large ophiolite unit (up to kms thick, extending tens to hundreds of km along strike) with supra subduction zone (SSZ) geochemical affinity that structurally overlies a thin (<500 m thick) sheet of high-pressure (HP), high-temperature (HT), primarily metamafic rocks called a metamorphic sole. The ophiolite generally lacks burial metamorphism and includes variably serpentinized peridotite at its base. The sole structurally overlies subduction complex rocks made up of oceanic materials (igneous part of oceanic crust and overlying pelagic sedimentary rocks, and clastic sedimentary rocks of trench fill affinity) and/or passive margin assemblages; some of the subduction complex may be metamorphosed under HP-low temperature (LT) conditions (such as blueschist facies). The field relationships suggest initiation of subduction within young (<15 My) and “hot” oceanic lithosphere and that the sole represents the first slice(s) of material transferred from the subducting to upper plate. Examples include the Neotethyan and northern Appalachian ophiolites and units beneath them, and the Coast Range ophiolite and subjacent Franciscan subduction complex of California. “Cold” subduction initiation assemblages lack SSZ ophiolite and island arc components and a metamorphic sole. Instead, the upper plate above the subduction complex is made up of continental lithosphere that last experienced significant heating during a passive-margin forming rift event. The protoliths of the rocks subducted were >70 My in age at the time of subduction initiation. The HP-LT subduction complex is composed of slices of continental crust and oceanic crust representing parts of a hyperextended continental margin. These field relationships suggest initiation of subduction along a continental margin within old (“cold”) hyperextended continental lithosphere. Examples include the Apennine subduction zone, exposed in Calabria, Italy, and the Alpine orogenic belt, both remnants of the Alpine Tethys.
