Defining the nature and location of a Late Devonian-Early Mississippian pycnocline in eastern Kentucky.

The ancient pycnocline closely parallels the Bedford-Berea delta front, suggesting major control by the delta. The continued influx of oxygen-rich, sediment-laden waters from the delta apparently prevented the northward and eastward migration of the pycnocline up the delta front. The introduced oxygen and sediment, however, were effective only in breaking up the pycnocline over a distance of approximately 25 to 40 km from the active delta fronts. -from Authors
