ripple bedding

The first member of Daye limestone yields hummocky ripple marks, hummocky cross bedding and graded bedding, which are the reflection of storm process.

其第一段岩石发育了丘状波痕、丘状交错层理及粒序层理，是风暴作用的反映；

Typical depositional structures of tempestite, such as radically arrangement of plate-like micrite gravel, hummocky lamination, load structure, grading bedding and ripple bedding are presented in the succession, indicating its accumulation in an offshore environment.

该风暴沉积的底面侵蚀构造清楚，板片状泥晶灰岩砾石呈菊花状排列，发育丘状交错层理、负载构造、递变层理和小波纹层理等沉积构造，为典型的浅海风暴岩。

The middle-level of tidal flat is presented as a zone of reworking, which is dominated by silt flats, or tidal channel systems, silt sediments and ripple bedding respectively.

改造带位于中低潮位线附近，以粉砂滩、潮沟系统、粉砂沉积和沙波层理为特征；
