苏北盆地金湖高邮凹陷构造样式探讨

根据二维、三维地震剖面构造解释成果,主要考虑断层的断距、断层切割的地层等因素综合分析,可把苏北盆地断层分为基底卷入型主干断层、基底卷入型次级断层和盖层滑脱(尖灭)型断层等3类。不同构造位置的变形样式不同,依据断层组合关系,将综合展现苏北盆地构造特征的金湖-高邮凹陷构造样式划分为地台基底卷入铲式正断层扇、正断层断阶带等10种类型。

The Structural Styles of Jinhu-Gaoyou Depression in Subei Basin

Fault throw and horizon were involved in systematical analysis on the basis of 2D or 3D seismic interpretation results,the faults in Subei Basin were roughly divided into basement-involved main faults,basement-involved secondary faults and capping-sliding or pinch-out faults.Jinhu-Gaoyou Depression is two inclined column sedimentary depressions in Northern Jiangsu Basin.And there are different deformation types in different structural positions,which could be divided into ten basic structural styles such as platform basement involved listric normal fault fan,normal fault terrace zone and so on.
