Have You Ever Seen The Mesmerising Salt Formations Of Iran

The layer of salt became covered with sediments washed down from the mountains by rainwater, and over time, the sediment layer thickened, became compact and weighed down heavily on the salt layer underneath. Under such circumstances, salt starts to behave like fluid leading to an interesting behavior known as salt tectonics. The weight of thousands of feet of sediments and rocks pushing down on the salt layer causes salt to rise up through the overlying rocks. When a weak spot is found in the overlying layer of sediment, the salt will push through it and form domes known as diapir. Sometimes a diapir will breach the surface and spread horizontally becoming a salt glacier.
