n: a dome that is caused by an intrusion of rock salt into overlying sediments. A piercement salt dome is one that has been pushed up so that it penetrates the overlying sediments, leaving them truncated. The formations above the salt plug are usually arched so that they dip in all directions away from the center of the dome, thus frequently forming traps for petroleum accumulations.

n: an anticlinal structure caused by an intrusion of rock salt into overlying sediments.this structure is often associated with traps for petroleum accumlations.

a usually large movement or intrusion of salt that gradually flows through the rock. Can create reservoir traps and can create casing collapse problems.
