An example of this geologic feature is the London Basin, where chalk and Lower Eocene sandstones lie confined below the London clay and above the Gault clay.
An example of this geologic feature is the London Basin, where chalk and Lower Eocene sandstones lie confined below the London clay and above the Gault clay. As the point of intake is above the level of the ground surface, this feature sunk into an aquifer through the overlying impermeable rock will result in water being forced up to the surface by hydrostatic pressure. Named after the region in France in which it was first observed, FTP, identify this geologic feature that consists of a well bored down to the point at which the water pressure is so great that it is forced to the surface.
