Flооding vast swaths оf the sоuthern Arabian peninsula and western Iran milliоns оf years agо, the Persian Gulf is nоw a cоnsiderably smaller bоdy оf water. The sea left behind enоrmоus amоunts оf salt as it evapоrated and the cоastlines receded. Sediments carried dоwn by precipitatiоn frоm the mоuntains eventually cоvered the salt layer, which became increasingly dense and weighted dоwn by the sediments as they thickened and cоmpacted.

As a result, salt begins to exhibit intriguing properties called salt tectonics, which manifest as fluid motion. The salt layer is forced to rise through the rocks because of the thousands of feet of sediments and rocks that press down on it. The salt will press through any cracks in the sedimentary layer above it to create domes called diapir. On occasion, a diapir will break the surface and expand laterally, transforming into a salt glacier.

You may find all of these magnificent salt formations throughout central, southwest, and southern Iran. The most striking instances can be observed in the Zagros Mountains, which flank Iran’s Persian Gulf coastline. As a result of numerous fractures and ridges created by the collision of the Arabian and Eurasian plates, the Zagros Mountains were able to rise to prominence.
Iranian salt glacier first
A salt glacier in the Zagros Mountains, measuring approximately 14 km in width.
According to UNESCO, there is no other place on Earth where such a concentration of salt domes can be observed. Although it is being examined for inclusion, the property is not yet a World Heritage property.
The southern portion of the Zagros Mountains is home to around 130 salt domes, which have an impact on the structure of this world-renowned simple folded system. The Namakdan Mountain is home to the world’s longest salt cave, which is more than 6.4 km long. Other geological features include salt glaciers, salt valleys, karst sinkholes, salt springs, and salt domes.
