Salt Diapirism
A diapir is region of lower density material (in this case salt) intruding into the overlying material. Salt Diapirs are formed through the slow process of evaporation, sedimentation, and compaction. A region experiences frequent flooding Subsequent evaporation will deposit salt The area is covered by later deposition where the overlying material will compact the deeper material. The density of the deeper sediment will increase while the density of salt is less affected by the pressure because of its crystal structure…
