Liyuan Rock Salt Mine in Puyang County,Henan Province is located in Qianliyuan deposition center of tectonic unit of Dongpu Sag.Based on the achievements of the predecessors,the development of Es1-salt in the area is determined through seismic section comparison and 10 122 m borehole construction.The salt rocks of the Shahejie Formation of Paleogene can be divided into two major sedimentary cycles.The filling and evolution model of salt lake basin is enriched by the sedimentary characteristics and conditions of Es 1-salt deposit.According to the sedimentary sequence characteristics of salt rock-paste salt rock-paste mudstone-soil sandstone in vertical and lateral direction of Es1-salt and the characteristics of paleo-environment and salt-forming mechanism of Es 1-salt deposit,the study results show that the genesis of Liyuan Rock Salt Depoist belongs to shallow water evaporation genetic deposit.
