Title: Sauk structural elements and depositional response in Ohio and northern Kentucky

Abstract

Three area structural elements were inherited from Precambrian events--the Rome Trough, Middle Run trough at the Grenville Line, and the Ohio platform on part of the more stable Grenville Province. They strongly influence the type of basal Sauk clastic and non-clastic deposits as documented from hundreds of wells in Ohio and adjacent northern Kentucky. These elements and the topography resulting from erosion during the Lipalian Interval most directly influence sedimentation during the onlap phase of the basal Sauk Sequence. Clastic wedge-base deposits are the Mt. Simon, Rome'', and Eau Claire formations. Deposition of the middle Cambrian Conasauga Shale coincides with the maximum marine onlap and wedge middle position. Upper Sauk Sequence deposition of the Knox Group carbonate rocks (Cooper Ridge Dolomite, Beekmantown Dolomite) and their interbedded clastic units (Steam Corners and Rose Run formations) represents the shallowing upward, pulsating clastic depositional events which anticipate the differential uplift and erosion that occurred later during the Taconic Orogeny and Early Ordovician hiatus. New Taconic structural elements involve the uplift of the central Ohio platform on the western part of the Grenville Province along reactivated, pre-Grenville sutures identified by CoCorp seismic lines. Platform uplift exposes lower Knox rocks to erosion. Younger Knox rocksmore » are preserved east of the fault line zone. The Appalachian Basin's western edge is marked at this time by the trend of the Rose Run and Beekmantown subcrop below the Knox Unconformity surface and by the edge of the high magnetic intensity basement.« less
