摘　　要：主要根据B,B/Ga和Sr,Sr/Ba的含量和比值大小来判断水的盐度,以及岩石类型和古生物组合,推断当时的沉积环境为过渡相偏海相的沉积特征。The salinity of water is determined by the content of Ba,Ga,Sr and the B/Sr ratio ,Sr/Ga ratio.On the basis of salinity,types of sedimentary rock and assemblage of palaeobiology,the sedimentary environment in upper Permian is concluded as transition facies to marine facies.
