The relationship between lake-level changes and lake water salinities has been confirmed as a covariance in closed-basin lakes.According to this principle,lake-level fluctuation history over time can be reconstructed using quantitatively calculation of paleo-salinities in boron concentration of lacustrine mudstone deposition.In this article,boron contents in lacustrine sediments as a salinity index,examples from the Tongtianhe section in the Tuotuohe area of northern Tibetan plateau,vertical lake-level curves inferred from paleo-salinities calculation data was reconstructed during late Oligocene-early Miocene.At the same time,applicability and limitation of this method were also discussed.The results showed that the salinity of paleo-lake water was from brackish to saline water during the upper Yaxicuo Formation deposition.It indicated that late Oligocene was an arid climatic period and lake level was a long low water stand in this area.Conversely,paleo-lake water salinity obviously dropped and reflected water level rise in lower Wudaoliang Fromation.It indicated that Tibetan Plateau climate evolved to enter a humid stage in early Miocene.
