摘要 河南省濮阳县梨园岩盐矿区位于东濮凹陷构造单元前梨园沉积中心。在前人研究的基础上,通过地震剖面对比、10 122 m钻孔施工确定了区内普遍发育沙一盐。将古近系沙河街组盐岩划分为两大沉积旋回,沙一盐的沉积特征、成矿条件丰富了盐湖盆地的充填演化模式。根据沙一盐垂向与横向上盐岩—膏盐岩—含膏泥岩—泥砂岩的沉积序列特点以及沉积古环境、成盐机理,综合分析认为梨园盐岩矿属于浅水蒸发成因。

Abstract: 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 Es1-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 Es1-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.
KeywordsRock salt mine   Es1-salt   Salt deposited in shallow water   Qianliyuan Sag   Metallogenic geological condition   Filling and evolution characteristics
