滨里海盆地东缘中段盐构造变形特征
|
摘要
利用地震剖面解释和构造编图,对滨里海盆地东缘中段下二叠统孔谷阶盐构造变形特征进行了分析。结果表明,孔谷阶含盐层系变形强烈,主要发育盐底辟、盐枕、盐滚、盐焊接、盐边凹陷和龟背构造等多种盐构造变形样式。不同盐构造规模差别较大,隆起幅度自东向西逐渐增大,平面展布具有明显的分带性。盐构造运动对周缘地层变形也产生了重要影响,形成了楔型褶皱地层,并导致盐间和盐上地层发育一些特征各异的断裂。盐构造运动受乌拉尔造山作用影响明显,强烈的盐构造活动主要发生在晚二叠世一三叠纪。
Using the interpretation of seismic profiles and structural mapping,the authors analyzed the deformation characteristics of salt structures in Kungurian of Lower Permian in the middle segment of eastern edge of Precaspian Basin.The results showed the deformation of Kungurian salt-bearing layer was very intensive,and salt diapirs,salt pillows,salt rollers,salt welds,salt-withdrwal minibasins and turtle structures developed well.The scales of different salt structures varied greatly and the uplifting amplitudes increased gradually from east to west with obvious zonations in plane view.The salt tectonism generated important influence on the deformation of peripheral strata,which was created wedge folded sequences and numerous faults between intrasalt and suprasalt strata. The intensive salt tectonism mainly happened in Late Permian and Triassic,which was effected by the Ural orogeny.
