Taking for example the salt rhythms of the Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin (which is a typical Paleogene saline lacustrine basin in eastern China), through a detailed study on cores, the authors have determined for the first time the Ⅳ-order salt rhythm based on Ⅰ-,Ⅱ-and Ⅲ-order salt rhythms which were determined previously and got to know that the sedimentary process following the sequence of desalinizing→salinizing and crystallization of salt minerals from halite rock→(mud-bearing) glauberite rock→dolomite-bearing mudstone (mud-bearing doloston)→mudstone→doloston→glauberite rock→halite rock. The authors also analyzed the Ⅳ-order salt rhythm and the correspondence between its sedimentary records and the fluctuation of the palaeosalinity of waters and the short-scale (0.05~1.0 ka duration) change of dry-moist palaeoclimate.
