巴里坤盐湖沉积亚环境组合的研究

盐湖沉积亚环境组合是盐湖发育演化在时间上和空间上的运动轨迹。巴里坤盐湖沉积组合的亚环境发育较为完善、典型。围绕巴里坤盐湖的多种亚环境有一定分布规律，且可识别。其中主要包括冲积扇、沙坪、泥坪、常年性河流泛滥平原、泉水池沼、暂时性河流泛滥平原、沙丘、暂时性盐湖、常年盐湖。从盐湖沉积亚环境组合的研究中可以看到巴里坤湖由淡水湖向微咸水湖以至盐湖发育演化的全貌。因此，盐湖沉积亚环境组合的研究不仅在探讨盐湖演化史中具有理论意义，而且对进一步寻找沙下湖盐类矿床也具有重要的实际价值。

THE RESEARCH OF COMPOSITION OF THE SEDIMENTARY SUBDIVISION ENVIRONMENT IN BARKOL SALT LAKE

Abstract The composition of sedimentary subdivision environment in salt lake is locus of the developing and evolveing of the salt lake in time and space. Barkol salt lake is a good example of this kind of lake. There are some distribution laws in the varied sedimentary subdivision environment of Barkol salt lake, and can be found, mainly consist of: alluvial fan, sand flat, mud flat, Permanent river flood plain, spring pond marsh, ephemeral river flood plain, sand dune, ephemeral salt lake and Permanent salt lake. There search of the composition of sedmentary subdivision environment in the salt lake can show the whole process of developing and evolving in Barkol lake,from fresh lake to slightly salt water lake then turn to salt lake. Therefore,researching on the comPOsition of sedimentary subdivision environment of the salt lake is not only value to research on evolveing history of a salt lake in theory, but also imPOrtant practice value to look for saline lake dePOSit under sand.
