Abstract
The bed rock in the vicinity of Cleveland, Ohio consists of flat-lying Upper Devonian and Mississippian shale, siltstone, and sandstone. It is the purpose of this thesis to provide a detailed bedrock geologic map of the Cleveland South 7 1/2 minute quadrangle and to include a description of the structure and facies relationships observed in the strata exposed in the map area. Although the bedrock is covered by Quaternary glacial material in most places, only the thickest deposits, in the Cuyahoga Valley area, were shown on the map. These deposits fill a rather deep preglacial valley. Other glacial deposits in the area, such as ground moraines, glacial lake deposits, and glacial lake beaches, are either covered or obscured by extensive urbanization. Field work was done from January through November, 1981 and included observation of formational contacts, measurement of stratigraphic sections, and collection of specimens for petrographic studies. Water-well logs on record at the Division of Water, Ohio Department of Natural Resources, were consulted to obtain contact elevations where exposures were not found.
