Diapir is a process in which material with a lower specific weight rises from the upper layers, breaks them and appears on the surface of the earth. In this process, the type of salt's response to the applied stresses creates specific geomorphological forms, which study is important due to the presence of oil resources, the establishment of human settlements, and the passage of communication routes.Failure to pay attention to salt diapirism studies in construction projects can cause their failure.In this research, which was conducted with the aim of investigating the geomorphology caused by salt diapirs, in the south of Semnan privance and with field, library and Remote Sensing methods, it was found that salt deposits cause the creation of specific geomorphological structures and shapes through the creation of tension. local cracks, surface dislocations and tensile fractures.Also, the fluidity of salt has been created on the surface structures and their dimensions are effective, and these structures, in turn, create local forces and control the morpho-geo-structural situation of the region.In addition, the dissolution process has played an important role in the formation of salt karsts in the region and has created significant shapes.Based on this, the geomorphological forms resulting from the Salt diapirismof the region were identified and in three groups of building forms including salt domes, salt anticlines and salt walls, salt karsts including dolines, ponors, karns and forms resulting from hydrological processes including valleys, springs, salt fluxes and salt glaciers were classified.
