Several lithofacies can be recognized within the Hindsville Limestone (Mississippian) in its type area near Hindsville, Madison County, Arkansas. Lithofacies are based on petrographic analysis of matrix and constituent particles, particularly ooliths and skeletal grains. Hindsville deposition began with skeletal calcilutite incorporating chert rubble from the underlying Boone Formation. Increasing energy produced a sequence of skeletal calcarenites and oolites, and the end of Hindsville deposition was marked by a return to impure skeletal calcilutite. Conodonts recovered from the Hindsville Limestone include species of Cavusgnathus and Gnathodus. On the basis of reported ranges of these elements, the Hindsville appears to correlate with part of the Middle Chesterian Series In its type region.
