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, fiche 1, Anglais, - salt%20diapir

Beaucoup de diapirs de sel s'étendent sur des dizaines de kilomètres et s'élèvent à 10 km ou plus des couches mères. La plupart sont zonés verticalement, passant du haut vers le bas des couches sommitales du «chapeau» à de l'anhydrite et, ensuite, à du sel.  2, fiche 1, Français, - diapir%20de%20sel
