Over time, the salt is covered with sediment and becomes buried. Since the density of salt is generally less than that of surrounding material, it has a tendency to move upward toward the surface, forming large bulbous domes, diapirs, sheets, pillars and other structures as it rises. If the rising salt diapir breaches the surface, it can become a flowing salt glacier. 3, record 1, English, - salt%20diapir

Many salt diapirs are tens of kilometres across, and have risen 10 km or more from the source beds. Most diapirs are zoned downward from cap rock, through anhydrite, to salt. 4, record 1, English, - salt%20diapir
