Highlights—'N Synch in the Paradox

As environments near mean sea level, mixed siliciclastic-carbonate shallow marine and coastal systems are sensitive to both relative changes in sea level and climate shifts.  Jordan and Mountney document facies, stratigraphy, and cyclicity in the Pennsylvanian-Permian lower Cutler beds of the Paradox Basin, USA, to explore variability in contemporaneously active eolian, fluvial, and shallow marine systems.  The results indicate that relative changes in sea level and climate shifts were linked, and how each of these distinct subenvironments responded to these changes.  The data provide a conceptual model for stratigraphic architecture within and among cycles and, based on these insights, offers a conceptual model for correlation strategies that should be applicable to other mixed systems.
