Glacial and Postglacial Deposits of Northeastern Ohio
(1988-03) Szabo, John P.; Carter, Charles H.; Bruno, Pierre W.; Jones, Edward J.
Recent high levels of Lake Erie have produced severe erosion and mass wasting along the shore. At the same time they have created excellent exposures of glacial and postglacial deposits east of Cleveland, Ohio. Glacial deposits consist of an older Coastal till and the Late Wisconsinan Ashtabula Till, whereas postglacial deposits generally are gravels, sands and silts. Lithofacies of the Ashtabula Till exposed at Sims Park in Euclid, Ohio, include sheared, massive diamicts and resedimented diamicts. The lowest sheared massive diamict previously identified as the Coastal till possibly represents a lodgement till deposited by Ashtabula ice. Beach deposits at Mentor Headlands resulted from construction of manmade structures. At Camp Isaac Jogues, deltaic sands overlie a sequence of diamicts, which has an unusually high carbonate content when compared to other sections along the shore. The geometry of the overlying sands and the facies sequence strongly suggest a river-dominated deltaic system. Two sand pits in beach ridges (one at the Warren level and the other at the Arkona level) farther inland contain coarse-grained facies that may represent an outwash plain or coastal barrier overlain by dune sand. A log dated at 13-4 ka was found at the Arkona level, 1 km south of the second pit.

Upper Pennsylvanian Steubenville Coal-Ball Flora
(1988-03) Rothwell, Gar W.
The Upper Pennsylvanian (Conemaugh Group) Duquesne Coal west of Steubenville, Ohio represents a deltaic peat-accumulating swamp, and is one of the best known of coal swamp floras. In a few places, the peat was infiltrated and permineralized by calcium carbonate prior to coalification, thus producing coal balls in which both morphological and anatomical structure of the constituent plant parts are preserved. The plant material represents primarily the community that inhabited the peat-accumulating environment, but some remains from near-swamp environments also are represented. The flora is relatively diverse, consisting of over 55 megafossil taxa of isolated organs that were produced by at least 25 species of plants. All five major groups of Pennsylvanian coal-swamp plants (i.e., Lycopsida, Sphenopsida, Pteridopsida, Pteridospermopsida and Cordaitales) are represented.
An Overview of the Upper Carboniferous Fossil Deposit at Linton, Ohio
(1988-03) Hook, Robert W.; Baird, Donald
The cannel coal that underlies the Upper Freeport coal (Westphalian D, Upper Carboniferous) at Linton in Jefferson County, Ohio, has yielded a remarkable fossil assemblage of at least 10 invertebrate taxa and nearly 40 vertebrate taxa. Spirorbid worms, crustaceans (primarily syncarids and conchostracans), and fishes (coelacanths, haplolepid palaeoniscoids, and xenacanth sharks) are the most abundant fossils in the deposit; small aquatic amphibians (including nectridean, temnospondyl, and aistopod species) are also common. Other arthropod and tetrapod taxa are exceedingly rare and possess obvious adaptations for terrestrial existence.
Fauna Associated With the Pennsylvanian Floral Zones of the 7-11 Mine, Columbiana County, Northeastern Ohio
(1988-03) McComas, Gregory A.; Mapes, Royal H.
Stratigraphically significant compression floras have been found in lower Conemaugh ironstone beds and lower Conemaugh dark argillaceous shales in the 7-11 Mine, Columbiana County, Ohio. The known fauna associated with the ironstone beds is limited to branchiopods, myriapods, and a single arachnid. The dark argillaceous shales yielded both invertebrate and vertebrate fossils including freshwater sharks, fish, ostracods, branchiopods, myriapods, arachnids, and insects. The absence of any marine fauna supports the contention that both the ironstone beds and the dark argillaceous shales were deposited in a freshwater environment.
Upper Pennsylvanian Compression Floras of the 7-11 Mine, Columbiana County, Northeastern Ohio
(1988-03) McComas, Melissa A.
Two compression floras have been discovered below the Brush Creek marine unit (lower Conemaugh) in Columbiana County, Ohio. One flora is preserved in freshwater ironstone beds 6 m below the Brush Creek and contains abundant pteridosperm and sphenopsid elements. The assemblage includes Sphenophyllum oblongifolium, Pecopteris candolleana, Danaeites emersonii and Odontopteris brardii, taxa previously recorded from younger strata. The second assemblage occurs within a 1.5-m-thick argillaceous, freshwater shale directly below the Brush Creek and yields abundant lycopod, cordaite, and conifer remains. The latter elements, some of which are permineralized with pyrite, represent the earliest occurrence of conifers in the eastern United States known to date.
Geology and Habitats of the Cuyahoga Valley National Recreation Area, Ohio
(1988-03) Corbett, Robert G.; Manner, Barbara M.
This field trip to the Cuyahoga Valley National Recreation Area in northeast Ohio has been prepared in association with the National Association of Geology Teachers' (NAGT) symposium entitled Public Lands and the Teaching of Geology. Stops are in a logical sequence to examine the geologic section, glacial deposits, and the following habitats: slump, hemlock ravine, upland dry woods, floodplain, slope, old field and wetland. Activity by man is minimal; sites are accessible and protected from future development; and the sequence of stops follows ages of bedrock, oldest to youngest. In order to protect the sites, national park policy prohibits collection of samples.
Late Devonian and Early Mississippian Distal Basin-Margin Sedimentation of Northern Ohio
(1988-03) Lewis, Thomas L.
Clastic sediments, derived from southeastern, eastern and northeastern sources, prograded westward into a shallow basin at the northwestern margin of the Appalachian Basin in Late Devonian and Early Mississippian time. The western and northwestern boundary of the basin was the submerged Cincinnati Arch. The marine clastic wedges provided a northwest paleoslope and a distal, gentle shelf-edge margin that controlled directional emplacement of coarse elastics. Rising sea levels coupled with differences in sedimentation rates and localized soft-sediment deformation within the basin help explain some features of the Bedford and Berea Formations. The presence of sand-filled mudcracks and flat-topped symmetrical ripple marks in the Berea Formation attest to very shallow water deposition and local subaerial exposure at the time of emplacement of part of the formation. Absence of thick, channel-form deposits eastward suggests loss of section during emergence.
Middle Devonian Carbonate Rocks and Shales of North-Central Ohio
(1988-03) Hatfield, Craig Bond
Middle and Upper Devonian marine strata are examined in quarries and natural exposures at six localities in Erie and Huron counties in north-central Ohio. The formations studied are the Lucas Dolomite, Columbus Limestone, Delaware Limestone, Plum Brook Shale, Prout Limestone, and Huron Shale. Lithologies and fossil contents suggest depositional settings ranging from open marine to tidal flat. Biostratigraphy indicates correlation of Columbus and Delaware limestones with the Onondaga Limestone and Marcellus Shale, respectively, of New York and with the Detroit River Group and Dundee Limestone, respectively, of the Michigan Basin.
Middle Devonian Stratigraphy and Conodont Biostratigraphy, North-Central Ohio
(1988-03) Sparling, Dale R.
Devonian sedimentation in north-central Ohio began in warm, somewhat restricted seas in which the Bois Blanc and Amherstburg formations (latest Early to earliest Middle Devonian) accumulated. Increased restriction, reflected by the Lucas Dolomite facies, prevailed until middle costatus-2.one time when marine transgression initiated deposition of the Columbus Limestone. A wave-erosional episode left a disconformity atop the Columbus that truncates the lower australis Zone near Sandusky and progressively lower levels southward; the uppermost costatus Zone is thus missing in central Ohio. The Delaware Limestone represents a transgressive-regressive cycle, apparently during kockelianus-'Z.one time, which was followed by an extensive erosional period in which three endemic species of Icriodus died out. The Plum Brook Shale is in the upper ensensis Zone (lowest upper Middle Devonian) and reflects the If T-R cycle. The Prout Dolomite contains a Middle varcus Subzone fauna and represents the Ila T-R cycle (Taghanic onlap). Regional correlatives of the Prout currently assigned to the Lower varcus Subzone are probably of Middle-varcus age. Considerable disagreement exists between the fairly extensive Middle Devonian conodont-biostratigraphic data in the Lake Erie region and recent correlations based on volcanic ash beds and/or geophysical logs.
