Some of the layers are obviously thicker than others - presumably the result of differences in annual deposition rates due to seasonal variations.|Pleistocene age varves at [[Scarborough Bluffs, Toronto, Ontario, Canada. The thickest varves are close to 2 cm thick. ]] A rhythmite consists of layers of sediment or sedimentary rock which are laid down with an obvious periodicity and regularity. They may be created by annual processes such as seasonally varying deposits reflecting variatio

韻律岩（英語：rhythmites）是一種沉積岩層，具有明顯的周期性和規律性。 它們的沉積是受年度的週期性（例如季節性）、短週期性(例如潮汐) 或長週期性(例如洪水) 等變化而造成的沉積物。韻律岩是研究在地質時代中地球演變的主要證據之一，例如對海平面變化、冰川變化和地球軌道變化等，都能提供有利證據。而且研究這些變化均有助于解釋有關氣候變化的問題。
