Geology of the Entracque–Colle di Tenda area (Maritime Alps, NW Italy)

The 1:25,000 geological map of the Entracque–Colle di Tenda area covers an area of about 130 km2 in the Italian Maritime Alps, between the Gesso and Vermenagna valleys. The map area is of great relevance since the Alpine units of this region sampled a geological nodal point in the Mesozoic, at the transition between two different sedimentation domains of the Alpine Tethys European palaeomargin (the Dauphinois basin to the NW and the Provençal platform to the SE). During the Cenozoic, this palaeogeographic hinge was progressively incorporated along multiple shear zone systems developed at the southern termination of the Western Alps arc.

Stone materials used for monumental buildings in the historical centre of Turin (NW Italy): architectonical survey and petrographic characterization of Via Roma

Abstract One of the peculiarities of Turin (NW Italy) lies on the presence of monumental arcades which mainly consist of stone material. These arcades, characterized by more than 12 km of interconnected paths, represent one of the widest city promenades of Europe and are an architectural, aesthetic and socio-economic example unique in the world. This paper, analysing the urban axis of Via Roma (Rome Street), aims to study the material used in arcade construction. The main stones occurring in Via Roma have been identified and described from a petrographic and mineralogical point of view in order to find out the corresponding geological units and original quarry sites. The minero-petrographic study is accompanied by an architectural survey that was performed applying different methods, as well as the geometric mapping and the perspective rectification of span-types, of block terminations and of other architectonical elements, in plan and in elevation, of the arcades. This allows us to emphasize the merging of cultural and scientific interest for the stone materials used in the historical architecture of a town closely interconnected to the surrounding Western Alps orogenic chain.

The Geodatabase of the Piemonte Geological Map: conceptual design for knowledge encoding

The Geodatabase of the Piemonte Geological Map was designed in a way suitable for linking the geological knowledge of the geological domain at hand to more general levels of knowledge represented in some Earth science ontologies and namely in a dedicated ontology (OntoGeonous). The paper describes how the two different knowledge levels are assimilated in the GeoPiemonte informative system, providing relations between the contents of the geodatabase and theencoded concepts of the reference ontologies.

The Meso–Cenozoic stratigraphic succession of the Col de Braus area (Maritime Alps, SE France)

ABSTRACT The 1:10,000 geological map here presented extends over about 32 km2 around the Col de Braus pass in the Maritime Alps (SE France). This area has attracted the attention of geologists since the late eighteenth century due to superb exposures of the Jurassic–Cretaceous Provençal succession, and has become a classic geological locality continuously studied until the present day. In this area, Early Cretaceous synsedimentary tectonics is evidenced by important lateral thickness and facies variations. This sector is presently placed at the western termination of a large structural domain extending from the westernmost Ligurian Alps into the French–Italian Maritime Alps, thus representing a key-area for understanding the structural setting of this part of the Western Alps.

TourInStones: application for mobile on ornamental stones of the city of Torino

The Piemonte mountains surrounding the city of Torino comprise a wide variety of rocks, characterized by a multitude of minerals, structures and colors. The Alps, for their long and complex history, offer awide variety of ornamental stone used in the town, over the centuries, for both aesthetic and structural reasons. TourInStones is a geo-touristic application for mobile of the center of Torino, where the visitor can find out which of these rocks have been used in palaces and historical monuments, witnesses and tangible symbols of the city. For the geologist, the naturalist, the curious, the student, the tourist, walk around Torino downtown represents a formidable opportunity to step on and observe granites, porphyries, gneisses, marbles and limestones, a richcollection exhibited in a open-air museum. In the proposed itineraries, you can stop in 25 sites, in each of which you can observe in detail a lot of ornamental stones of historical and scientific interest.
