The complex relations of the Goddard Formation with older rocks in the Madill-Aylesworth area of Marshall and Bryan Counties, Okla., is attributed to an unconformity as well as previously postulated faulting. The Goddard is believed to have been deposited over the Caney shale and older rocks which had been truncated by erosion of a Late Mississippian anticline. This local uplift and erosion may have been coincident with similar events in the Ouachita province and is correlated with the widespread Late Mississippian to Early Pennsylvanian unconformity (the lacuna between the Kaskaskia and Absaroka sequences).
