根据古构造坡折带控制层序类型和层序构成模式的思路 ,通过南堡凹陷古近系同沉积构造发育特征的分析 ,认为南堡凹陷古近系存在同沉积断裂坡折带和同沉积背斜挠曲坡折带 2种类型 ,由此决定了南堡凹陷古近系主要发育了同生断裂坡折型层序和同沉积背斜挠曲坡折型层序 ,建立了这 2种类型层序体系域构成模式 。

6) faulted deposit
断裂沉积
补充资料:断裂带
亦称“断层带”。有主断层面及其两侧破碎岩块以及若干次级断层或破裂面组成的地带。在靠近主断层面附近发育有构造岩,以主断层面附近为轴线向两侧扩散,一般依次出现断层泥或糜棱岩、断层角砾岩、碎裂岩等,再向外即过渡为断层带以外的完整岩石。断层带的宽度以及带内岩石的破碎程度,决定于断层的规模、活动历史、活动方式和力学性质,从几米至几百米甚至上千米不等。一般压性活压扭性断层带比单纯剪切性质的断层带宽。在一些大型的断层带中,由于被后期不同方向的断层切错,和夹有一些未破碎的大型岩块,只是断层带的结构趋于复杂化,从而在近代的断层活动中容易形成运动的阻抗,是应力易于积累和发生地震的场所。
