摘　　要：本文通过分析、研究苏北盆地洪泽盐盆古近系古新世阜宁组四段岩盐常量元素与微量元素分布特征,参考国内外常用的对比分析方法,采用Sr/Cu、Sr/Ba等微量元素比值,还原了研究区洪泽盐盆古近系古新世阜宁组四段岩盐沉积的古气候及沉积环境特征,通过研究区内常量元素含量高低反映出本区石盐矿物质来源成因信息,原始卤水性质,认为研究区在阜宁组四段岩盐沉积期总体处于干旱炎热气候,较好地印证岩盐矿产沉积对古气候的要求,且本区岩盐沉积为较为典型的海相沉积环境。By analyzing and studying the distribution characteristics of major elements and trace elements in rock salt of the fourth section of the Palaeogene Funing Formation of the Hongze Salt Basin of the North Jiangsu Basin,and referring to the commonly-used comparative analysis methods at home and abroad,the paleoclimate and sedimentary environment characteristics of the rock salt deposition of the fourth section of the Palaeogene Funing Formation of the Palaeogene system of the Hongze Salt Basin are restored by using the ratios of Sr/Cu and Sr/Ba.The content of major elements in the study area reflects the origin of halite minerals in the area,and nature of the original brine.It is considered that the study area is generally in an arid and hot climate during the rock salt deposition in the fourth section of Funing Formation,which well confirms the requirements of rock salt mineral deposits on paleoclimate and the rock salt deposition in this area is a typical marine sedimentary environment.
