摘要： 苏北盆地洪泽凹陷历经多次地质事件，在赵集次凹阜宁组四段沉积了规摸较大的盐类矿床，研究地质构造演化对盐矿成矿的控制作用，对该区域盐矿的开采及利用具有重要意义。研究认为，洪泽凹陷的构造演化对区内盐矿的形成具有重要控制作用，它不仅控制着聚盐盆地的形成和发展，也直接影响着盐类物质来源、卤水演化、盐类沉积和盐矿的分布，总体上控制了盐湖的形成、发展直到消亡的全过程，确保了盐矿沉积形成后的保存完整性，区内盐矿总体具有良好的圈闭特性，具备建造大规模石油或天然气地下储库的基本地质条件。

Abstract: Hongze sag in Subei basin experienced multiple geological effects, and deposited a large amount of salt mine in Zhaoji subsag. The study on the control mechanism of the tectonic evolution to the forming process of the salt mine is significant to the mining and utilization of the salt mine. It is found that the tectonic evolution of the Hongze sag is important to the forming progress of these salt mines. The tectonic evolution not only controls the forming and the development of the salt basin, but also has a direct impact on the salt material sources, brine distribution, salt deposition and distribution. The tectonic evolution controls the forming, development and the subduction process of the saline lake. The sag also protects the integrity of the salt mine. Based on the above analysis, the salt basin has a good trap characteristics, which can satisfy the basic geological conditions of forming underground oil/gas storage.
