The vertical movement of Eocambrian Salt Range Formation has resulted in the salt diapirism and halo-kinesis in the area.
(2016) [3] suggested a wide variety of geological agents as triggering mechanisms for SSDS such as liquefaction or fluidization by earthquake-induced shock waves, adjustment to gravity in successions with reversed density gradients, shear stress, sudden overloading by mass-transported sediments, slumping or slope failure, large-scale deformations resulting from tectonic activity, and intermediate or small size SSDS commonly result from exogenic processes such as glaciotectonism and overburden-induced diapirism.
They assume a present geometry and assess the fluid system at a single point in time, whereas in reality, these fluid systems evolve along with the salt structure, inheriting characteristics from each stage of sedimentation and diapirism. To evaluate the fluid system and thermal structure development through time, we must understand how the fundamental evolution of salt structures is going to affect the fluid system and temperature distribution in the minibasins.
Some researchers suggest that this anticline has formed due to a combination of diapirism of Hormuz Salt and continued movement of the Sarvestan Fault (Dehbozorgi et al., 2010 and references therein).
Most Maykopian out-crops are tied with phenomena of diapirism, which have caused the deposits to be in the surface or down along the kernels of numerous diapiric folds.
The wide distribution and relatively constant thickness of the Boss Point Formation suggests that it did not cause significant differential loading and was deposited during a time of modest passive diapirism (Waldron et al.

An unusually high altitude of the inclined Middle Ordovician limestone strata, observed at Tornimagi and Porguhauamagi, may be caused by (1) huge erratics broken by ice from the edge of the North Estonian Klint or (2) diapirism. According to Suuroja (2005), the klint cannot be a source of such erratics, because carbonate rocks at the klint are about 5 m thick and the youngest limestone there is of Kunda age, while at the Vaivara Sinimaed they are over 25 m thick and the youngest one belongs to the Uhaku Regional Stage.
