This transition in the Upper Devonian deposits is gradual and marked by upward-thickening and -coarsening sequences of evenly-bedded turbidites and lenticular beds of crossbedded sandstone.

Higher energy mass flow deposits such as debris flows, massive and. Later, Walker () and Walker and Harms () re-interpreted the marine–nonmarine transition of the Foreknobs Formation equivalent in Pennsylvania as a succession of prograding muddy shoreline “motifs” because of the lack of classic deltaic facies, such as coarsening-upward successions capped with prominent distributary mouth-bar and.
