Abstract Ancient Mahu lake was a typical carbonate saline lake in the Early Permian where abundant carbonate minerals(mostly with positive ion of sodium) were deposited. Based on the data of major elements,oxygen and carbon isotope,petrology and mineralogy characters of systematic samples of study core section,rhythm characteristics and their mechanism were discussed. The study core section alternated with soda layers and sedimentary tuff layers. Light soda layers are relatively pure nahcolite and sodium,and have major elements characteristics as follows: High content of Na₂O,low content of CaO,MgO,SiO₂ and Al₂O₃. Dark sedimentary tuff layers developed white spot shaped minerals of shortite,and have major elements characteristics as follows: Lower content of Na₂O,high content of CaO,MgO,SiO₂ and Al₂O₃. Both soda layers and sedimentary tuff layers have high values of δ¹⁸O and δ¹³C,which indicate that sedimentary water has high salinity during the depositional period of whole layers. Light soda layers have higher δ¹⁸O value,which indicate intense evaporation when soda deposited. The study core section can be explained into multiple stages of hot and dry climate and relative humid climate according to the value of δ¹⁸O/δ¹³C. Origin of different carbonate minerals formed in different layers could achieve. Dark layers formed when palaeoclimate was warm and humid that water input was more than water output,and shortite crystaled inter-particles when palaeoclimate transformed into hot and dry. When palaeoclimate transformed into hot and dry, calcium ion and magnesium ran out,nahcolite and baking soda crystaled with strong evaporation. Frequent changes of palaeoclimate have produced saline cycles of soda layers and sedimentary tuff layers.
