滨里海盆地东缘盐构造特征及其与乌拉尔造山运动关系
|
摘要
通过对滨里海盆地东缘地震剖面的解释,揭示了丰富多样的盐构造变形特征及其与乌拉尔造山运动的关系。滨里海盆地东缘盐构造变形样式主要包括盐底辟、盐枕、盐滚、盐焊接、龟背构造和盐边凹陷等,表现出明显的分带变形特征,自东向西依次为盐焊接带、盐滚带、盐枕带、盐底辟带。盐层控制了盐上层和盐下层的构造变形,以盐层为界,上构造层主要发育正断层,下构造层主要发育逆断层。平衡剖面分析表明,滨里海盆地东缘盐构造变形主要经历了重力变形和差异负载变形两个阶段,并与乌拉尔造山运动有紧密联系。乌拉尔造山运动引起滨里海盆地东缘地层发生倾向反转,进而控制了盐层沉积及随后的重力变形和差异负载变形过程。
Based on the interpretation of seismic profiles,salt structures in the eastern margin of the Precaspian Basin and their relationships with Ural orogeny were analyzed.The salt structures in this study area include salt diapirs,salt pillows,salt rollers,salt welds,turtle structures and minibasins,which are featured by the zonation of deformation.There are zones of salt weld,salt rollers,salt pillows,and salt diapirs from the east to the west.Salt controls the tectonic deformation of the suprasalt and the subsalt,in which normal faults and thrust faults were developed,respectively.The cross sections show that salt experienced two stages of deformation including the gravity spreading and differential loading halokinesis,and the salt structures had close relationship with the Ural orogeny.Ural orogeny had reversed the strata in the eastern margin of the Precaspian basin,and exerted strong influence on salt deposition and the subsquent deformation of salt driven by gravity spreading and differential loading.
