Cyclic rhythmites (tidal rhythmites) provide fine-scale resolution of deposition within specific types of tidal systems. Rhythmites of this kind have been reported from many sites throughout geologic time; nonetheless, they are particularly widespread and common within the Carboniferous basins of the eastern and mid-continental United States. These rhythmites have great potential for providing information regarding the local, regional, and global controls on their deposition. Widespread occurrence of cyclic rhythmites within these basins outlines a hierarchy of parameters that controlled deposition. These controls include: (1) local and regional depositional setting, (2) elevated paleotidal ranges, (3) sequence stratigraphic and basinal conditions, (4) a unique paleoceanographic configuration, and (5) specific conditions of astrophysical alignments.

Tidalites: Processes and Products - Tidal processes are important agents of sediment transport and deposition in most marine coastal zones. Recent development of better tools for recognizing tidal deposits (e.g., tidal bundles and tidal rhythmites) has also revealed that such deposits are much more common and extensive than previously thought. This volume presents the latest ideas on tidal sedimentation, including exciting new work concerning the tidal flats of the Wadden Sea, the area where modern-day studies of tidal sedimentation began; the origin, interpretation, and uses of tidal rhythmites; and the sequencestratigraphic context of tidal sediments.
