From Wikipedia, the free encyclopedia
Cyclic sediments (also called rhythmic sediments[1]) are sequences of sedimentary rocks that are characterised by repetitive patterns of different rock types (strata) within the sequence. Processes that generate sedimentary cyclicity can be either autocyclic or allocyclic, and can result in piles of sedimentary cycles hundreds or even thousands of metres thick. The study of sequence stratigraphy was developed from controversies over the causes of cyclic sedimentation[2].
