| 摘 要： | 花状构造以其独特的构造样式而成为在剖面上识别走滑构造的重要标志.经典的花状构造包括正花状构造和负花状构造.渤海湾盆地南堡凹陷发育一种新型的花状构造——背形负花状构造.在三维地震剖面上,背形负花状构造是由一束向上、向外撒开的大多数为正离距的离散的走滑断层或转换伸展断层所限定的,下部呈向形,上部呈背形的组合样式.平面上,褶皱和相关正断层呈雁行排列.背形负花状构造发育于南堡凹陷转换伸展的构造背景.浅层的背形是由转换伸展断层牵引塑性的盖层而形成的一种强制褶皱.该构造经历了牵引背斜形成和背斜脊部断裂-塌落两个发育阶段.背形负花状构造普遍发育于渤海湾盆地的新近系.

| Abstract: | Flower structures are specific modes of formation,and their distinctive characteristics make them important criteria for the identification of a strike-slip zone in vertical cross-sections and on seismic profiles.Two element types of the classical flower structures were respectively negative and positive flower structures.There is a new kind of flower structure termed antiformal negative flower structures in Nanpu sag,Bohai Bay basin.A antiformal negative flower structure in 3D seismic profiles from the Nan... |
