Abstract Saline lakes in Hulunbeier league cover as usual a relatively small area,featuring complexity of the compositions of the lake waters in contrast to simplicity of the compositions of the massive salt sediments. This simplicity is meant by the salt sediments consisting essentially of no other minerals than concentration- varying mirabilite or natron. In spite of this, the comPOsitions of the salt sedimentS still fluctuate not only with the positions in which the lakes lie but also with...

Abstract Saline lakes in Hulunbeier league cover as usual a relatively small area,featuring complexity of the compositions of the lake waters in contrast to simplicity of the compositions of the massive salt sediments. This simplicity is meant by the salt sediments consisting essentially of no other minerals than concentration- varying mirabilite or natron. In spite of this, the comPOsitions of the salt sedimentS still fluctuate not only with the positions in which the lakes lie but also with the changes in sedimentary conditions. Hulunbeier's saline lakes rest mainly in palaeochannels,depressions between dunes and intermountuine depressions, with sources of salt materials from surrounding areas. Evalutions of these lakes are accompanied by sedimentary differentiations of the salt materials due to differences between their solubilities and changes in depositional conditions,as a result, to lead to different salt sediments in contiguous lakes,even in a single lake.

呼盟盐湖面积都比较小,盐湖卤水组分较复杂,但其中所沉积的相应的厚层盐类沉积物组分却比较简单,多为不同纯度的芒硝或泡碱层。盐类沉积的组分和盐湖公布地区有关,也受沉积过程中沉积环境的变化所控制。呼盟盐湖主要形成于古河道盆地、砂丘间洼地和丘陵地区的山间洼地,盐类物质来自周缘地区。由于盐类物质溶解度变化规律的不同和沉积环境变化,盐湖演化过程中产生盐类物质沉积分异作用,因此即使在相邻的盐湖和同一盐湖中,也可形成不同的盐类沉积。

The irregular body of water being considered on to a unit cube in this article, so it can be applied equally well to large tidal ranges. The transformed set of equations are then solved by finite difference techniques using a variable grid designed to retain the second order accuracy of space grids.

A 3-D time dependent, dimensionless coordinate numerical model for flow-salt-sediment movement in tidal estuaries is briefly described. The irregular body of water being considered on to a unit cube in this article, so it can be applied equally well to large tidal ranges. The transformed set of equations are then solved by finite difference techniques using a variable grid designed to retain the second order accuracy of space grids. The suspended sediment part of the model employs the conceptions of the rate of erosion-siltation in the bottom boundary conditions, the parameters in which are defined by combining analysis of laboratory data and model data. The effective settling velocity formula, which is obtained in Changjiang estuary, is applied in the part of computing suspended sediment concentration. The model had been verified with the field data from Changjiang estuary. The results show that the model can be used to simulate the movement of flow-salt-sediment in tidal estuaries.

There were cyclothems consisted of evaporite rocks,deep color mudstones or shales and deep water turbidity sediments of Peleogene Sha-4 member in Dongying sag,which was salt lake sedimentary assemblage with more than 1000m in thickness.The evaporite rocks consisted of halite and anhydrite rocks mainly existed in north and centre of Dongying sag where the deep fractures developed.The fossil assemblage indicated that the climate was semi-dry and semi-moist in Paleogene Sha-4 member in Dongying sag.Analyzed the sedimentary characteristics and depositional conditions,the authors considered that the brine in deep water was the substance basis of the salt sediment,the salt in deep strata was the source of brine and the deep fractures in the north of the sag were the paths where the salt substance entered the developing sag.The deep water genesis model of salt lake in Dongpu sag which can be compared with that of Lake Kivu,was put forward after the discussion.The new field in subsalt strata exploration can be found on the basis of the lithofacies assemblage of source rock and evaporite rock.

东营凹陷下第三系沙四段广泛发育的蒸发岩类与暗色泥、页岩和深水浊积砂体呈现明显韵律层 ,为厚度达千米的盐湖沉积。通过分析了该地区蒸发岩地层的沉积特征和沉积条件 ,认为东营凹陷沙四段蒸发岩类的物质基础是深层卤水 ;深部古老地层中的盐类物质是其盐源 ;凹陷中北部的同沉积深大断裂是沟通凹陷与地壳深部盐类物质的通道。在此基础上提出东营凹陷沙四段盐湖的深水成因模式 ,可与东非裂谷基伍湖和东濮凹陷下第三系深水成因盐湖对比
