Bedrock fission‐track analysis, high‐resolution petrography and heavy mineral analyses of sediments are used to investigate the relationships between erosion and tectonics in the Western Alps. Along ...the Aosta Valley cross‐section, exhumation rates based on fission‐track data are higher in the fault‐bounded western block than in the eastern block (0.4–1.5 vs. 0.1–0.3 mm yr−1). Erosion rates based on the analysis of bed‐load in the Dora Baltea drainage display the same pattern and have similar magnitudes in the relative sub‐basins (0.4–0.7 vs. 0.04–0.08 mm yr−1). Results highlight that climate, relief and lithology are not the controlling factors of erosion in the Western Alps. The main driving force behind erosion is instead tectonics that causes the differential upward motion of crustal blocks.

The conservation study of the Roman Heritage in Aosta (Italy) is aimed at understanding the causes of the superficial chromatic alteration, which has affected the Roman ruins (I sec a. C.) since the ...last decades. The Roman monuments are built of pudding stone, a quite irregular and inhomogeneous conglomerate of fluvial origin. The stone in place started showing superficial chromatic alteration as reddish and pinkish areas in the last fifty years only. First results show that the alteration might be due to the oxidation of ferrous ion. The iron oxides spread out in the secondary calcite, thanks to fluid circulation through porous material, and crumble the pudding stone surface.
In metamorphic areas, paleogeothermal gradients are difficult to properly estimate, leading to great uncertainty in exhumation rate calculations based on fission track analysis. In this work, a new ...multidisciplinary approach based on fluid inclusion analysis, structural analysis and fission track dating has proven to be able to constrain the late stages of exhumation of metamorphic rocks. The study area is located in the Sesia–Lanzo unit of the Western European Alps, along the Hone shear zone. Kinematic analysis at different scales unraveled a polyphase postmetamorphic deformation history, constrained in the P–T space thanks to laboratory investigation of kinematically referenced fluid inclusions coupled with the analysis of the rheological behavior of quartz and feldspar inside syn-kinematic veins. The resulting P–T path points to an increasing paleogeothermal gradient from 18 to 30 °C km

after greenschist facies metamorphic conditions, and provides a reference framework for a quantitative interpretation of fission track data in terms of exhumation rates and fault throws. According to fission track data, throws accommodated by the Hone shear zone between 33 and 30 Ma are on the order of 4.5 km, and would be underestimated by ∼25% if a “normal” steady gradient was assumed for the whole post-metamorphic history of the area. The deepest portions of this structure were exhumed thanks to the activity of the E–W fault system that accommodated a throw of ∼4 km between 28 and 20 Ma, and a throw of ∼0.8 km during the last 20 Myr.
Aim of this article is to discuss the relationship between local powers and local churches starting from a peculiar case study: Cogne’s valley between XIIIth and XVth century. Set in Aosta valley, in ...the heart of Western Alps, this place was connected with many different local powers: the Prince of Savoy, who had the territorial control of the whole region; the bishop of Aosta, who exercised a jurisdictional power over the valley of Cogne and, as chief of the diocese, was responsible for the cure of souls of the inhabitants; the Priory of Sant’Orso, who administered the Cogne’s parish. The superposition of different powers produced many conflicts, which saw the community of Cogne acting as the fourth essential protagonist. Through the analysis of heterogeneous set of documents (ecclesiastical visitations, franchises, donations), the article shows how the community was able to gain its space of action thanks to the negotiation with the different powers active on the territory.

L'étude des bijoux - notion complexe pour la période prise en examen - et de leurs représentations, s'appuie sur l'analyse des images en deux dimensions de la Vallée d'Aoste, du Piémont, de Ligurie ...et de Lombardie aux XIVe et XVe siècle. Elle vise à observer les contextes et les types de support permettant d'observer des détails comme les objets précieux, ainsi qu'à déterminer les grands groupes de commanditaires des images mettant en scène ces objets. Elle vise ensuite à analyser la fréquence d'apparition des différents bijoux et accessoires de parure, ainsi qu'à déterminer les catégories de personnages les plus ornées, tout en confrontant ces résultats avec les autres sources à notre disposition: mobilier archéologique, objets d'orfèvrerie, documentation comptable, inventaires après décès, lois somptuaires, récits de chroniqueurs, sermons, correspondance, poésie, ainsi que les Lapidaires dédiés aux gemmes. Sont abordées les particularités mises en avant par les images, qui insistent sur les différentes valeurs morales attachées à chaque type d'objet de parure, à l'endroit du corps auquel il était destiné ainsi qu'au rang de celui qui les portait.Le recours à plusieurs études relevant du domaine de l'anthropologie historique permet d'observer le rôle important des occasions qui requéraient le port de ces objets ou qui en commandaient les échanges, découlant des nécessités imposées par un cérémonial très ritualisé, lors duquel les objets de parure jouaient un rôle de représentation et de protection.L'analyse s'oriente sur la « stratégie » déployée par les images et leurs commanditaires, au sein d'une logique des apparences visant à légitimer leur position.
The study about jewels and adornment accessories - a complex notion for the period in examination - and their representations, leans on the analysis of the two-dimensions images produced in Aosta Valley, Piedmont, Liguria and Lombardy in the 14th and 15th century.It aims at observing contexts and types of medium allowing images to show such details as jewels and adornment accessories, when still visible, and to determine the different groups of people who subscribed the images where these objects appear.It aims at analyzing the frequency of appearance of the various jewels and dress adornments, as well as determining which are the most decorated categories of characters, while confronting these results with the other sources at our disposal: archeological and goldsmiths' work finds, account books, inventories, sumptuary laws, chroniclers narratives, sermons, correspondence, poetry, and a particular genre of literature dedicated to gemstones: Lapidaries.The particularities advanced by images insist on the various moral values attached to every type of jewel and adornment object, their location on the body, as well as the rank of their owner.The recourse to several studies belonging to the historic anthropology domain allows focusing on the important role played by the occasions which required the bearing of these objects or which commanded their exchanges, ensuing from a ritualized ceremonial, during which the finery objects played a role of representation as well as protection.Finally, the analysis turns on the "strategy" displayed by images and, especially by those who ordered them, joining within logic of appearances, in order to legitimize their position.
Lo studio dei gioielli – nozione complessa per il periodo preso in esame – e delle loro rappresentazioni, si basa sull’analisi delle immagini a due dimensioni prodotte nella Valle d’Aosta, in Piemonte, Liguria e Lombardia ne Trecento e Quattrocento. Mira innanzitutto ad osservare quali sono i contesti ed i tipi di produzione che permettono di osservare dettagli come gli accessori ornamentali, quando questi sono ancora reperibili, così come a determinare i grandi gruppi di promotori delle immagini raffiguranti questi oggetti. Mira poi ad analizzare in modo quantitativo la frequenza delle apparizione di quei differenti tipi di gioielli ed accessori preziosi, nonchè a determinare quali sono le categorie di personaggi più ornati, pure confrontando questi risultati con le altre fonti a disposizione. Tra queste si annoverano reperti archeologici e oggetti di oreficeria, ma anche fonti scritte : documentazione archivistica contabile, inventari, leggi suntuarie, opere di cronisti, sermoni, corrispondenza, poesia, così come une tipo particolare dedicato alle gemme : i Lapidari. Sono così evidenziate le particolarità messe in luce dalle immagini, che insistono sulle differenti caratteristiche morali legate ad ogni tipo di oggetti presi in conto, alla parte del corpo alla quale era destinato, così come al rango sociale di chi lo portava. Il ricorso a parecchi studi che rientrano nel campo dell’antropologia storica permette di osservare il ruolo importante delle occasioni che richiedevano di ornarsi con questi oggetti o che ne determinavano gli scambi, il che dérivava dalle necessità imposte da un cerimoniale molto ritualizzato, nel quale quegli oggetti preziosi assumevano nello stesso tempo una funzione di rappresentazione et di protezione. Infine, l’analisi si orienta sulla « strategia » sviluppata dalle immagini, e sopratutto dai loro donatori, iscrivendosi in una logica delle apparenze che tendeva a legittimare la loro posizione.
The aim of this research was to compare fat quality of three categories of the Aosta cattle breeds by fatty acid composition. Samples of longissimus thoracis et lumborum from 12 calves, 11 young ...bulls and 11 cows of Aosta Red Pied and Black Pied were bought at retail. Fatty acids content showed in most cases, except for C18:1, significant differences between the three categories. Veal calves had the lowest proportion of SFA and highest of PUFA, therefore they had the best PUFA/SFA ratio but the worst n-6/n-3 ratio due to the highest proportion of C18:2n-6. Besides veal calves was healthier by having best atherogenicity and thrombogenicity indices. Black Pied young bulls, in comparison to Red Pied young bulls, showed a significant lower proportion of C10:0, C18:1, and a significant higher proportion of C18:2n-6, C18:3n-3 and C20:4n-6. Consequently they had a significant lower MUFA content but a higher PUFA content therefore a significant better PUFA/SFA ratio.
