| Reevaluation of the Upper Devonian stratigraphy of the southern Lake Erie shore region indicates the presence of a Type Two stratigraphic sequence within which occur smaller cycles recognized over long distances. The larger cycle has an eustatic origin; other recognized cycles largely have an eustatic origin, and deposition has been affected by regional tectonic adjustments. When synthesized with published data from northeastern and mid-continental North America describing regional structural trends, the data from this research suggests reactivated Precambrian basement faulting may have exerted allocyclic control on deposition within this portion of the Appalachian basin. Such controls can mimic sequence stratigraphic deposition. A sea-level curve suggesting the regional response to basin adjustment within the eustatic curve is derived from interpretation of Upper Devonian units in the southern Lake Erie region. |
