The Paris Basin is a geological basin of sedimentary rocks. It overlies geological strata folded by the Variscan orogeny. It forms a broad shallow bowl in which marine deposits from throughout periods from the Triassic to the Pliocene were laid down.
Paris lies in the so-called "Paris Basin," a low-lying continental shelf that over geologic time was occasionally submerged in ocean waters leaving behind marine sedimentary deposits (e.g., limestone, excavated from the underground "Quarries of Paris" and used to construct many of the city's buildings).
Geologic map of France. Divisions in French Regional Geology. The regional geology of France is commonly divided into the Paris Basin, the Armorican Massif, the Massif Central, the Aquitaine Basin, the Pyrenees, the Alps, the Côte languedocienne, the Sillon rhodanien, the Massif des Vosges, the Massif Ardennais, the Alsace graben (Rhine graben) and Flanders Basin.
Paris lies within the Paris Basin, a geological bowl-like shape created by millennia of sea immersion and erosion. [2] Much of north-western France spent much of its geological history as a submerged sea water coastline, but towards our era, and the formation of our continents as we know them, the then relatively flat area that would become the ...
Along these margins it descends very abruptly to the surrounding grabens. These margins also show the highest elevations, the plate being gently inclined to the Northwest where the basement rocks disappear under the Mesozoic cover of the Aquitaine basin and the Paris Basin. This somewhat simplistic model is locally disturbed by fault lines and ...

PARIS (AP) — French officials inaugurated on Thursday a huge water storage basin meant to help clean up the River Seine, set to be the venue for marathon swimming at the Paris Games and the swimming leg of the Olympic and Paralympic triathlons.
The region lies in the center of the Paris Basin and consists of limestone plains with a gently rolling relief. Its principal rivers are the Seine and its tributaries, the Marne, Oise and Aisne. The province of Île-de-France encompasses the north-central territories of Val-d’Oise, Seine-et-Marne, Seine-Saint-Denis, Ville-de-Paris (Paris ...
