The geological map of Piemonte Region (Italy) is a graphic representation of the geology of the region, grounded on a large geodatabase, that can be also browsed as an interactive scalable map (GeoPiemonte Map) using a WebGIS application. The Map, produced at 1:250,000 scale, is the first original release of the 'GeoPiemonte Map' project. The geological data represented on the map derive from a thorough revision of available geological maps and literature, integrated with unpublished original data. The revision and harmonisation of existing and new data have been based on explicit criteria used for the classification of geologic units and their representation on the Map. These criteria firstly aimed at providing a lithostratigraphic, hierarchic subdivision of Piemonte geologic units and describing them using shared concepts and vocabularies, consistent with IUGS Descriptive Standards for the Geosciences. ARTICLE HISTORY
The 1:25,000 scale geological map of the Monviso massif encompasses an area of 61 km 2 , where different tectonic units of the Monviso Meta-ophiolite Complex (i.e. the Basal Serpentinite Unit, the Lago Superiore Shear Zone, the Viso Mozzo Unit, the Forciolline Unit and the Vallanta Unit) and different Quaternary deposits (i.e. alluvial, gravitative, glacial and periglacial deposits) have been distinguished. The Monviso Meta-ophiolite Complex is an important remnant of the Mesozoic Tethyan lithosphere stacked in the Western Alps, and consists of various sequences of serpentinized peridotites, metagabbros, metabasalts and metasediments, that are deformed by syn-to late-metamorphic folds and displaced by syn-to post-metamorphic faults. The geological map presented here provides new detailed lithological, structural and morphological data regarding (i) the tectonostratigraphy of the central sector of the Monviso Meta-ophiolite Complex and (ii) the Quaternary glacial and post-glacial evolution of the Monviso massif.
The External Ligurian and Epiligurian Units in the Northern Apennines of Italy are tectonically juxtaposed with the Tertiary Piedmont Basin along the Villalvernia -Varzi Line, which represents a regional scale fault zone, E-striking. Our map, at the 1:20,000 scale, describes the tectono-stratigraphic evolution of this sector that resulted from multistage faulting along that fault zone. Four main tectonic stages are defined on the basis of the crosscutting relationships between mapped faults and stratigraphic unconformities: late Priabonian -Rupelian, Chattian -early Miocene, late Serravallian -Tortonian, and late Messinian -early Pliocene. Our results demonstrate that since the late Burdigalian, the Villalvernia -Varzi Line was sealed by the gravitational emplacement of a chaotic rock body. The deposition of the late Serravallian -early Messinian succession is controlled by NW-striking strike-slip faults that crosscut to the west the Villalvernia -Varzi Line. Extensional tectonics related to regional scale N-dipping tilting characterized the late Messinian -early Pliocene time interval.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
