The Aquitaine Basin is the second largest Mesozoic and Cenozoic sedimentary basin in France after the Paris Basin, occupying a large part of the country's southwestern quadrant. Its surface area cover
The Venus of Brassempouy, Upper Paleolithic. The first representation of a human face.
Lower Portlandian micrite from the La Tour-Blanche anticline; east-southeast-west-northwest-oriented strike-slip fault with horizontal slickolites and a calcite-filled pull-apart. Thus the anticline was also affected by transtensional wrenching motions.

The Massif Central is one of the two large basement massifs in France, the other being the Armorican Massif. The Massif Central's geological evolution started in the late Neoproterozoic and continues
Aquitaine Basin
…west of Narbonne, the basin is overridden by Pyrenean thrusts. The northeastern boundary of the basin is formed by the arcuate basement outcrops of the Massif Central. Via the 100 km wide Seuil du Poitou in the northeast, the basin is connected to the Paris Basin. In the far north, the basin abuts the east–west-oriented…
Geographical position of the Massif Central in France.
Neoproterozoic paragneis of the Arverne domain near Nontron, Dordogne. The light-coloured graywacke layer is boudinaged and dips steeply to the NNE.
Shatter cone from the Rochechouart impact structure
Paragneiss from the Arverne domain. This sample demonstrates the structural complexity found in the Massif Central. The left hand side shows a porphyroblast in C/S attitude with sense of movement top to the Southwest (D1-Phase). The right hand side also shows a porphyroblast in C/S attitude but with sense of movement top to the Northwest (D2-phase). The layers above it glide off to the right producing southeast-vergent small-scale folding (D4-phase)
