ABSTRACT

During Triad's fall 1996 and spring 1997 drilling programs to the Second Berea Sandstone in Lodi Township, Athens County, Ohio, I recognized the Second Berea was climbing in time and becoming a younger depositional unit when traced from west to east in Lodi Township. Drill cuttings from the Second Berea indicate a change from a calcareous sandstone (lower unit) to a non-calcareous sandstone (upper unit). Looking back at Pepper et al. (1954) Professional Paper 259 on the Berea Sandstone, their model of the Second Berea confused me. Their model shows the Second Berea as an offshore bar with the eastern margin toward the seaward side. If this model is correct, why does the Second Berea become a younger stratigraphic unit moving eastward and not an older unit? For this presentation I constructed west to east cross sections and mapped the Cleveland Shale thickness to reevaluate Pepper's Second Berea offshore bar model.
