Lithofacies and Mineralogy of the Late Wisconsinan Navarre Till in Stark and Wayne Counties, Ohio
(1991-03) Storck, Richard J.; Szabo, John P.
The Navarre Till deposited by ice of the Killbuck lobe in Stark and Wayne counties is the oldest till of late Wisconsinan age in northeastern Ohio. The type section of the Navarre Till is located near the margin of glaciation in Stark County. Interpretations of the diamict at the type locality include a meltout till overlying shale. Other sections in the study area consist of meltout or flow tills which occur as stratified or massive diamicts interbedded with silts, sands, and gravels. Diamict interpreted as lodgement till occurs only at one section.
Evolution of Till Stratigraphy in Union County, Ohio
(1991-03) Angle, Michael P.
Initial, Superconducting Super Collider-related fieldwork in Union County employed the stratigraphic scheme successfully used by the Division of Geological Survey in north-central Ohio. Descriptions and laboratory analyses of tills collected from outcrops and cores demonstrated that this scheme worked remarkably well. Tills, from youngest to oldest, were the clayey Hiram and Hayesville tills; the compact, silty upper Millbrook Till; the clayey middle Millbrook Till; and the sandy lower Millbrook Till. The sandy, noncompact Navarre Till appeared to be absent. The clayey Hiram and Hayesville tills become thin at the Powell Moraine and are absent south of the moraine. Southward from the Powell Moraine, a noncompact, sandy till closely resembling the Navarre Till was observed. West of Marysville, the entire sequence of tills becomes appreciably more clayey. Observed variations in the till stratigraphy may reflect an actual change of till sheets, a facies change, or both. Historically, stratigraphic schemes developed by Totten, Forsyth, and Goldthwait have been utilized in the Scioto Lobe. As a result of these multiple schemes, a complex and somewhat overlapping variety of names are available for tills observed in Union County. This paper reviews the relevance and utility of previous schemes, suggests correlations between them, and makes recommendations for their use. Additionally, a summarized scheme for Union County is presented.
Correlation of the Three Tills of Logan County, Ohio
(1991-03) Forsyth, Jane L.
The author identified three Late Wisconsin tills in Logan County in 1956, related them to soils in 1965, and named them the Marysville, Bellefontaine, and Pickrelltown in 1967, but included no correlations, which have since become established and are reported here. The Marysville Till is the youngest, is clay-rich and almost pebble-free, and has a shallow soil (Morley-Blount). Next older (south) is the Bellefontaine, with a loamy, pebbly texture and also a shallow soil (old Miami 6A). Oldest and southernmost is the loamy, pebbly Pickrelltown Till, which has a deeper soil with a B3 horizon (old Miami 60).
Historical Development and Problems Within the Pennsylvanian Nomenclature of Ohio
(1991-03) Larsen, Glenn E.
An analysis of the historical development of the Pennsylvanian stratigraphic nomenclature, as used in Ohio, has helped define and clarify problems inherent in Ohio's stratigraphic nomenclature. Resolution of such problems facilitates further development of a useful stratigraphy and philosophy for mapping.
Lithostratigraphy of the Grant Lake Limestone and Grant Lake Formation (Upper Ordovician) in Southwestern Ohio
(1991-03) Schumacher, Gregory A.; Swinford, E. Mac; Shrake, Douglas L.
The Grant Lake Limestone, including, in ascending order, the Bellevue, the Corryville, and the Straight Creek Members, and the Grant Lake Formation, including, in ascending order, the Bellevue, the Corryville, and the Mount Auburn Members, are herein defined as lithostratigraphic units in southwestern Ohio. Regional bedrock mapping, shale-percentage and geophysical logs, and mean shale percentage of lithostratigraphic units demonstrate a progressive change from a limestone-dominant stratigraphic section in the Maysville, KY, region to a shale-dominant stratigraphic section in the Cincinnati, OH, region. The Grant Lake Limestone is redefined to account for the progressive decrease in limestone content observed northwestward away from Maysville, KY. The Grant Lake Formation is introduced to describe the shaledominant lateral equivalent of the Grant Lake Limestone in the Cincinnati, OH, region. The Bellevue Limestone, the Corryville Formation, and the Mount Auburn Formation are reduced to members because, in some cases, they are not mappable at 1:62,500 or smaller scales. The Straight Creek Member is introduced to describe the limestone-dominant lateral equivalent of the shale-dominant Mount Auburn Member. The limestone-dominant and shale-dominant lithologies of the Grant Lake Limestone and the Grant Lake Formation can be recognized in shale-percentage and geophysical logs. Correlation between logs led to recognition of these stratigraphic units in the subsurface of southwestern Ohio.
The Middle Run Formation: A Subsurface Stratigraphic Unit in Southwestern Ohio
(1991-03) Shrake, Douglas L.
The Middle Run Formation, a recently described and named sedimentary unit, was encountered below the Mount Simon Sandstone (Upper Cambrian) in the Ohio Department of Natural Resources (ODNR), Division of Geological Survey (DGS) core hole DGS 2627 in Warren County, OH, (39°33'57N latitude, 84°06'51 W longtitude). The formation is primarily a fine- to medium-grained, subangular- to subrounded-grained, siliceously and hematitically cemented, tightly compacted, grayish-red (5 R 4/2), lithic arenite. It also contains rare intervals of calcite-cemented granule- to pebble-sized lithic-fragment conglomerates, and has an average porosity of less than 2%. Sedimentary features in the formation include horizontal and ripple laminations and crossbedding. A total of 582 m of this formation's estimated 1100-m thickness were cored. The Survey core DGS 2627, reposited in the Survey's core library, is designated as the type section for the Middle Run Formation. A suite of geophysical-logs for the core hole is on file at the Survey.
Field Guide to Berea Sandstone Outcrops in the Black River Valley at Elyria, Ohio: Slumps, Slides, Mud Diapirs, and Associated Fracturing in Mississippian Delta Deposits
(1991-03) Wells, Neil A.; Coogan, Alan H.; Majoras, Judy J.
Synsedimentary slumps of Berea Sandstone and diapirs of Cleveland and Bedford Shales are seen in complex delta-front facies at Elyria, Lorain County, OH. Analysis of orientations of fractures, bedding, and crossbeds helps interpret the history of deformation. In many instances, initial conjugate shears formed with least stress parallel to paleoflow, down the paleoslope. Some conjugate joints subsequently become normal and strike-slip faults. Some blocks of Berea show tilting and/or sliding to the extent of creating recumbent overturned drag folds in subjacent shales. Deformation of slide bases varies from brittle to plastic (fluidized). These features support the view that irregular thicknesses of Berea Sandstone are the result of deformation and are not fillings of deep valleys eroded in a Red Bedford delta. We suggest that the Berea represents rapid progradation of sands over formerly deep-water shales following rebound at the end of foreland-basin subsidence.
Middle Devonian (Givetian) Silica Formation of Northwest Ohio - Description and Road Log
(1991-03) Camp, Mark J.; Hatfield, Craig Bond
Middle Devonian marine strata are examined in this field trip to the former Medusa South-South Quarry (now the property of the France Stone Company) at the famous Silica locality of Lucas County in northwest Ohio. The formations exposed are the Dundee Limestone, Silica Formation, and Ten Mile Creek Dolomite. Lithologies and profuse fossil content of the Silica Formation suggest an open marine depositional setting contiguous with seas in Ontario and New York. Biostratigraphy indicates correlation of the Silica Formation with part of the Hamilton Group of New York, Pennsylvania, and West Virginia; with the Plum Brook Shale of north-central Ohio; with the Bell Shale of Michigan; and, with the Hungry Hollow Formation of southwestern Ontario.
A Field Guide: The Kelleys Island Glacial Grooves, Subglacial Erosion Features on the Marblehead Peninsula, Carbonate Petrology, and Associated Paleontology
(1991-03) Snow, R. Scott; Lowell, Thomas V.; Rupp, Robin Frank
This field trip provides an opportunity to reevaluate the processes responsible for some subglacial bedrock erosion features in northern Ohio. Beginning in the 1830s, quarrying operations on Kelleys Island, OH, have uncovered several giant grooves on the bedrock surface. One such groove remains for investigation today. There is agreement that these features were formed mainly in a subglacial environment, but specific agents and mechanisms remain matters of controversy. The dominant second-order features within the giant groove are cigar-headed ridges with furrows present on sides, at heads, and commonly well in front of heads. Fractal analysis of high-resolution transverse profiles highlights the geometric differences between smallscale features (striations) and large-scale erosion forms, with the break in roughness occurring at a scale of 10 cm (4 in). The genesis of the large-scale features warrants further analysis and discussion. Elsewhere on the island, wave-cut notches and chutes along joints can be observed as results of Holocene shoreline erosion. A large glacially-planed surface on the nearby Marblehead Peninsula displays a range of erosional forms more typical of the region. These forms are developed in the same formation exposed in the Kelleys Island giant groove, the Devonian Columbus Limestone, consisting of highly fossiliferous, subtidal marine carbonates. The glacially smoothed surfaces at Marblehead and in the Kelleys Island groove provide many opportunities to examine fossil communities in planar section, and to evaluate the influences of the variable petrology and individual fossils on bedrock erosion by subglacial processes.
Field Guide to Joint Patterns and Geomorphological Features of Northern Ohio
(1991-03) Dean, Stuart L.; Kulander, Byron R.; Forsyth, Jane L.; Tipton, Ronald M.
Bedrock in northern and northwestern Ohio consists of Middle Paleozoic carbonates and shales and is pervasively jointed. The regional joint pattern and chronology, established by the characteristics of joint traces, mineralization, and surfaces, reveal a complex history of fracture development. Joint studies along the north-south trending Bowling Green fault zone indicate that northwest-trending joints formed first in response to extensional stresses associated with differential dip-slip movement in this fault zone, or by left lateral movement along this zone.
