Abstract The palaeo-water characteristics of the Paleogene Shahejie Formation in Nanpu sag of Bohai Bay Basin was poorly studied. Taking the Member 1 of Shahejie Formation in southern Nanpu sag as an example,we studied the palaeosalinity and palaeo-water depth by many means. Based on special algae fossils and chemical element ratios including Sr/Ba and Rb/K,the palaeosalinity was interpreted as brackish water to semi￣saline water. The palaeoclimate was humid with fluctuation by analyzing Sr/Cu ratio and sporopollen fossils. The relative palaeo-water depth was reconstructed according to the change of Mn/Fe ratio,kerogen types,algae fossils and Tulotomoides. By synthetic analysis with the authigenic clay minerals,sedimentary structure and sedimentary facies,the palaeo-water depth interval was calculated by weighted average method. The results show that it was shallow water sedimentary environment with the quantitative palaeo-water depth ranging from 4,m to 15,m during the depositional period of the top of middle submember of Member 1 of Shahejie Formation in Nanpu sag. During the depositional period of lower submember of Member 1 of Shahejie Formation, the palaeo-water depth changed from 4 m to 30 m. It is indicated that the palaeosalinity and palaeo-water depth depended relatively on the palaeoclimate and ancient terrain background.
