Drowning intervals are ubiquitous in many carbonate platform successions. These intervals represent the cut-off or suffocation of carbonate production during a rapid submergence of a platform as a result of a relative sea-level rise, an increased rate of subsidence, active tectonism, or a combination of these processes. Drowning is often succeeded by siliciclastic deposition. Platform drowning intervals in the Maryville Limestone are typically characterized by a subaerial exposure surface immediately overlain by either deeper water basinal shales or a ''back-stepping'' carbonate package grading into basinal shales. The authors present field and petrographic evidence of a stratigraphic interval (14 m) of more gradual drowning that is not preceded by subaerial exposure and is overlain by deeper water shales (Nolichucky Formation). This interval marks the boundary between the Maryville and the Nolichucky formations, and is a third order sequence boundary.
