摘要: 羽状交错层理由倾向相反的两组纹层组成,中间一般不发育隔层,主要形成于滨海(湖)环境。在宁夏香山群第二亚群发现了类似沉积构造,但两组纹层之间却发育有规模较大的隔层。前人研究认为,该套地层主要形成于浊流环境,尽管存在分歧,但较深的水体环境是勿庸置疑的。这与羽状交错层理形成的环境完全不同,故将其命名为类(似)羽状交错层理。目前似乎只有内波沉积理论能够较为圆满地解释深水环境中这种特殊的牵引流沉积现象。

Abstract: Herringbone cross-bedding is often found in coastal lake environment. It is composed of two laminas with inverse inclination. The interlayer is absent between the laminas. One kind of similar sedimentary structure was found in the second sub-group of Xiangshan group in Ningxia by the writers, in which a large scale interlayer exists between the laminas. The previous researchers believed that this set of formation is mainly formed in turbidity current setting. However, it is far from the sedimentary setting of the herringbone cross- bedding. This paper calls it similar herringbone cross-bedding. It seems that the internal wave sedimentation theory can only be used to satisfactorily explain the special sedimentary phenomena formed by traction current in deep water setting.

Key words: herringbone cross-bedding, similar herringbone cross-bedding, Xiangshan group, internal wave
