The multiphase tectonic activities above clearly controlled the move and gather of salifying brine, the strongth of salt-forming and the deposition of salt-bearing strata. With the pass of time, the salt-bearing strata thickened gradually from northwest to east and southeast, and the distribution of the thickness trended towards complicated; the measurement of the halite deposition extended towards east too; in the early Palaeogene and the Neogene, strong multiphase tectonic activity was a disadvantage to salt-forming, but in the middle and late Palaeogene, weak multiphase tectonic activity, which resulted in slow and sustained subsidence of the basin, was greatly advantaged to it, especially to potash-forming.
