Terrains géologiques virtuels
Sédimentologie - Stratigraphie - Découverte géologique - Utilisation
Les “field trips” virtuels permettent de favoriser et d’améliorer la réussite des étudiants. Ils proposent une approche pédagogique numérique avec des visites en 360°, enrichies de contenus interactifs, sur des sites reconnus d’intérêt géologique.
Sédimentologie
Combe Valton
Bourgogne-Franche-Comté
This outcrop corresponds to an old open quarry in the Jurassic carbonate formations . It is possible to clearly observe the microfacies and paleo-current sedimentary structures characteristic of a shoreface environment.
Combe Saint-Joseph
Bourgogne-Franche-Comté
This outcrop corresponds to an old open quarry in the Jurassic carbonate formations. It is possible to clearly observe the paleo-current sedimentary structures constituted by subaqueous dunes, showing planar cross-bedding structures.
Combe à la serpent
Bourgogne-Franche-Comté
This outcrop corresponds to an old open quarry in the Jurassic carbonate formations. It is possible to clearly observe the microfacies and paleo-current sedimentary structures characteristic of a shoreface environment.
Baie d'Authie Nord
Hauts-de-France
The Authie estuary represents the mouth of the Authie river which opens in the eastern Channel. In the North bank from The Authie estuary, different morphosedimentary units characterize the estuary and are organized on either side of a channel.
Baie de Somme
Hauts-de-France
The Somme estuary represents the mouth of the Somme river. It is of macrotidal type, with hight amplitude from 9 to 10m and the tide is dominated by flow currents.
Talant belvédère
Bourgogne-Franche-Comté
This outcrop corresponds to an old open quarry in the Jurassic carbonate formations. It clearly shows the succession of the sedimentary rock units with different microfacies and sedimentary structures characterizing the sedimentary environment of a carbonate platform.
Baie d'Authie Sud
Hauts-de-France
The Authie estuary represents the mouth of the Authie rivers. In the South bank from Authie estuary, different morphosedimentary units characterize the estuary.
Stratigraphie
Carrière de la Roche Blain
Normandie
The Roche Blain quarry exposes Jurassic outcrops, visible as a Jurassic marine transgression event on the Brioverian basement. Cephalopods are among the most abundant macrofossils in the marly and calcareous beds of the section.
Découverte géologique
Falaises d'Etretat
Normandie
The site of Etretat is world-famous for their cliffs composed by chalk, constituted essentially of calcareous nannofossils (coccolithes), where numerous level of flint are present. Etretat is located at the northwest border of the Paris Basin, in the Pays de Caux. The littoral section show a stratigraphic interval between the Upper Cenomanian and the Middle Coniacian.
UTILISATION
Les field trips virtuels constituent des visites immersives sur le terrain grâce à des photos 360 réalisées par drone ou au sol. Chaque field trip est enrichi de contenus interactifs comprenant : la localisation géographique par différentes méthodes (cordonnées géographique GPS, photo satellite, et plan de situation) ; la mesure de la direction par rapport au Nord ; des photos de panoramas interprétés ; des photos de lames minces ; des commentaires ; des modèles 3D sur sketchfab ; des liens html.
Chaque photo 360 est correctement orientée par rapport au Nord, il est donc possible en utilisant la boussole de retrouver les directions des structures géologiques en regardant leur orientation dans la photo 360.
