Meter-scale lithologic cycles are a common motif in shallow-water carbonate and mixed carbonate siliciclastic systems.  Myrow et al. study stratigraphic patterns of contemporaneous Upper Cambrian carbonate and mixed carbonate-silcicilastic systems of the Laurentian paleocontinent.  They reveal that although both types of systems include cyclic strata, each records fundamentally distinct dynamics and processes.
