Lors de l'analyse de séquences sédimentaires anciennes, il est important de reconnaître les dépôts de plage qui signalent la position du zéro marin et l'amplitude de la marée. Une séquence de plage idéale est caractérisée par les structures sédimentaires suivantes (de bas en haut): calcarénite à stratification en auges (rides de houle) - calcirudite à foresets fortement inclinés (confluence swash - backwash) - calcarénite à laminations planes ou en festons, riches en "keystone vugs" vers le haut (zone du swash) - calcarénite à fines lamines horizontales (salcretes) ou rides éoliennes - calcarénites à stratifications en auge de grande amplitude, fortement bioturbées (dunes côtières), interrompues par des niveaux laminés à base érosive (washh...
