A unit can be uplifted into a regime of lower [[Normal hydrostatic pressure|normal pressure]]. The encapsulated fluid then is at a pressure higher than that found at the new depth in surrounding [[formation]]s where the fluid is under normal constraints. | A unit can be uplifted into a regime of lower [[Normal hydrostatic pressure|normal pressure]].
