| 摘 要： | 回顾了最近十余年来国外对周期性潮汐沉积物，特别是潮汐韵律层的研究进展，系统介绍了几种从古代沉积物中识别出来的潮汐周期，包括基本潮汐（半日潮，全日潮和混合潮），大一小潮周期以及一些长周期波动等。最后，对潮汐韵律层在推测地史时期地－月系的演化历史及计算短期沉积速率中的意义作了评述。

| Abstract: | This paper presents a systematic review of the study of cyclic tidal sediments,especially tidal rhythmites,and some ancient tidal periods recognized from sediments,including basic tides (semidiurnal,diurnal and mixed),neap-spring tides,and several long-term fluctuations. In addition,the implications of tidal rhythmites for the earth' s rotation and the history of the earth-moon system in geological past,and the estimation of short-term sedimentation rates are discussed. |
