摘　　要：描述了东濮凹陷的含盐层序特征,利用同位素、微量元素分析了成盐物质的来源,认为该凹陷成盐物质以陆源为主,局部受海侵物源的影响;阐述了成盐期古气候和古地理特征,并总结了盐岩的沉积模式,认为该凹陷盐岩的沉积模式为振荡式深盆浅水成盐模式;阐述了东濮凹陷盐岩的平面展布特征。The characteristics of salt bearing-sequence in Dongpu Depression are described, the source of salification materials is analyzed by using isotope trace element, it is considered that the salification materials in the sag are dominated by terrigenous sources and partialy influenced by transgressive sources. The characteristics of palaeoclimate and palaeogeography at salification stage and sedimentary mode of the saline rocks are summarized. It is considered that the sedimentary mode is oscillation and deep basin shallow water salification. Characteristics of plane distribution-of the saline rock in Dongpu Depression are described as well.
