Aquitaine Basin, Sedimentary basin in southwestern France
The Aquitaine Basin is a funnel-shaped plain in southwestern France that opens toward the Atlantic Ocean with a gently sloping floor. It is filled with layers of sedimentary rock accumulated over millions of years, creating the flat landscape you see today.
The basin's geological formation started in the early Triassic period and continued with the buildup of marine sediments during later periods. Over time, these layered deposits created the foundation for the landscape and soil we see today.
The region has been shaped by farming and wine production for centuries, with these practices deeply woven into how people live and work here. Vineyards and grain fields define the landscape and remain central to local life.
The basin is well connected by highway networks that link towns and rural areas across the region. The flat terrain makes travel and navigation straightforward for visitors moving through the landscape.
Below the surface lie significant oil and gas deposits that have fueled regional energy production for decades. Deeper layers also hold freshwater reserves that supply drinking water to millions of people.
