中文摘要	淮阴凹陷浦口组的二段和三段为一套厚度达千米的膏盐岩-碎屑岩沉积体系,对含盐层系的主要沉积相类型及其特征的分析和研究,结合该区构造、钻井、测井、地震、盐岩化学等资料的综合分析,初步认为该套厚层盐岩主要与半深湖沉积有关,深部古老地层中的盐类物质是盐岩的主要盐源,盆地边缘及内部的深大断裂是沟通凹陷与地壳深部盐类物质的通道.
英文摘要	The Pukou Formation in Huaiyin depression is composed of cyclothemes of salt rocks, mudstones and shales, which formed saline-lake sedimentary assemblage of more than 1000 m thick. During the aggra-dation of Pukou formation, the Huaiyin area was a wide lake which consisted of alluvial fans, littoral fa-cies, shallow-lake facies and semi-deep-water facies. The saline sediments were formed in the semi-deep-water saline lake. In this paper, based on the geologic, seismic, geochemical, and palaeobiogical data, the sedimentation environment of Pukou Formation and the genesis of saline sediments are discussed. Nowadays, there are three viewpoints on the formation of saline substances: (1) the saline substances from the marine transgression, in association with arid or semi-arid climate, and precipitated as saline de-posits. (2) in the high-mountain-deep-basin environments, the saline substances from the weathering and leaching rocks such as carbonates, gypsolytes or other salinastones. (3) the saline substances derived main-ly from the deep sources which were evidently related with faults or volcanism of the tectonic zone. In this paper, the author agrees with the third point. The reasons are as follows: ?the sedimentary characteris-tics: the saline deposits mainly belong to sodium-sulfate-chloride type. The sediments are cyclothems of saline rocks, mudstones and shales, ?the depositional conditions: many faults developed in Huaiyin de-pression during the formation of the saline deposits. ? the asymmetry of salinity. ? the palaeontological characteristics. All above-mentioned proofs show that the salt in deep strata was the major source and the deep fractures were the paths thtough which the salt substances entered into the depression.
