if the encapsulated unit is buried deeper, its original pressure is carried to a higher pressure environment. If the rock cannot compact, the trapped pressure is abnormally low for the new depth.
if the encapsulated unit is buried deeper, its original pressure is carried to a higher pressure environment. If the rock cannot compact, the trapped pressure is abnormally low for the new depth.
As long as a rock unit remains encapsulated by impermeable rocks, it becomes underpressured by burial as faulting or as downwarp occurs.
