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。
After many geological events in the Hongze Sag of the Subei Basin, the larger salt deposits have been deposited in the fourth member of the Funing Formation in the Zhaoji sub-set to study the controlling effect of geological tectonic evolution on mineralization of salt mines. Mining and utilization of the mine is of great significance. The study suggests that the structural evolution of the Hongze sag plays an important controlling role in the formation of salt mines in the area. It not only controls the formation and development of salt basins, but also directly affects the source of salt, brine evolution, salt deposition and salt The ore distribution generally controls the formation and development of salt lakes until the demise of the entire process to ensure the integrity of deposit after the salt deposit is formed. The salt deposits in the area generally have good trapping characteristics and the ability to build large-scale oil or gas The basic geological conditions of underground storage.
