摘要：

The laminations consist of carbonate grains and micrite in layers up to 2mm thick capped by thin (0.1-0.3mm) drapes of organic matter. Each couplet was generated by mixed or semidiurnal tidal events, during which carbonate sediment was mobilized and deposited by the dominant tide and organic material settled from suspension during slackwater conditions. Laminae thicken and thin systematically in a vertical sequence as a result of neap-spring tidal current fluctuations that occur during a lunar month. -from Authors
