Devonian-Mississippian Boundary, Batesville District, Northeast Arkansas, Steven H. Terry, Deborah E. Coogan

Journal of the Arkansas Academy of Science

The total record of the Devonian System in the Batesville district, northeast Arkansas is represented by the Penters Chert. Conodonts recovered from a thin limestone near the top of the Penters confirm a Lower Devonian age assignment, making this the oldest Devonian formation in northern Arkansas. The contact of the Penters Chert and the overlying Mississippian section is a marked disconformity. Excellent exposures in the bluffs along the east side of the White River exhibit unpredictable distributions of lower Mississippian strata. The most complete representation of the Mississippian sequence includes a basal sandstone of the Bachelor Formation, overlain by several …

Geologic Mapping From Aerial Photography In The Boston Mountains, Northwestern Arkansas, Mikel R. Shinn

Journal of the Arkansas Academy of Science

Aerial photography has been employed to map stratigraphic and structural features in the Boston Mountains of Washington and Crawford Counties, Arkansas. Exposures of resistant stratigraphic units within the lower Atoka Formation were delineated on a series of large scale aerial photographs over an area of about 150 square miles. With the aid of a Bausch & Lomb Zoom Transfer Scope, the positions of the units were subsequently transferred to 1: 24,000 scale topographic base maps. The presense of east trending anticlines and synclines and a series of low displacement normal faults is reflected by either gradual or abrupt changes in …

Devonian Sandstone Lithostratigraphy, Northern Arkansas, Jeffery D. Hall, Walter L. Manger

Journal of the Arkansas Academy of Science

Two areas of Devonian sandstone development may be recognized in northern Arkansas. In northwestern Arkansas, the Clifty Formation comprises a massively bedded, super mature quartz arenite of Middle Devonian age overlain by thinner bedded, phosphatic quartz arenite and chert breccia of the Sylamore Sandstone Member, Chattanooga Shale (Upper Devonian). This sequence overlies Ordovician strata (Powell or Everton) and is succeeded by the Chattanooga Shale and strata of Lower Mississippian age. In north-central Arkansas, the Clifty Formation is absent and the Chattanooga Shale may develop sandstone at its base and top. Occasionally the Chattanooga Shale is absent and the entire interval …

Stratigraphy Of The Lower Atoka Formation, Crawford County, Arkansas, John G. Chapman, James P. Thornton, Doy L. Zachry

Journal of the Arkansas Academy of Science

The Atoka Formation (Pennsylvanian) of northwestern Arkansas is a complex succession of sandstone and shale units. Sandstone units in surface sections near the base of the formation in northern Crawford and southern Washington Counties may be correlated with units in the subsurface of the Arkoma Basin. The basal sandstone units of the Atoka Formation as recognized in the Arkoma Basin are correlated with thin, discontinuous sandstones within the Trace Creek Member of the Bloyd Formation in surface exposures to the north. Vertical grain size profiles, electric log profiles and the configuration of thickness trends suggest that lower Atoka sandstone units …

Stratigraphy, Depositional Environment And Structure Of The Taconic Allochthon, Central Washington County, New York, Louise D. Jacobi

Geology Theses and Dissertations

The Taconic Allochthon contains rocks of Cambrian (?), Cambrian and Ordovician age. It measures approximately 200 kilometers by 25 kilometers and is located in contiguous sections of New York, Vermont, Massachusetts, and Connecticut. The rocks are predominantly slates with lesser amounts of arenites, wackes, limestone, chert, and conglomerates. All have been subjected to chlorite or biotite grade metamorphism and two tectonic deformations. The study area in central Washington County, New York, contains most of the Taconic sequence, and because of both natural and man-made exposure it is more accessible than most other locations. A lithostratigraphic column has been identified which …

Nebraska Mineral Operations Review, 1976, Raymond R. Burchett, Duane A. Eversoll

Conservation and Survey Division: Faculty and Staff Publications

During 1976, there were active in Nebraska 41 limestone quarries; 592 sand, gravel and silt or siltstone pits; 8 clay or shale pits; 24 sandstone pits; and 1 peat pit. These 666 mining operations disturbed 820 acres and restored 78 acres during the year.

Water Resources Data For Nebraska Water Year 1976

Conservation and Survey Division: Faculty and Staff Publications

Water resources data for the 1976 water year for Nebraska consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 146 gaging stations; stage and contents for 9 lakes and reservoirs; water quality for 40 gaging stations, 18 ungaged stations, 27 partial-record flow stations, and 96 wells; and water levels for 66 observation wells. Also included are 114 crest-stage partial-record stations and 12 low-flow partialrecord stations. Additional water data were collected at various sites, not part …

Long-Distance Turbidite Correlations In The Horseshoe Abyssal Plain, William H. Hoyt

Geology Theses and Dissertations

Few studies on modern abyssal plain turbidites have attempted to assess the lateral extent of individual units and few have therefore been able to provide any information on the evolution of turbidity deposits across long abyssal plain distances. In the 4755 m-deep Horseshoe Abyssal Plain, ten distinct lithologic units (six of these Iberian Peninsula-derived turbidites) were delineated in nine piston cores on the basis of stratigraphic position, thickness (range of 20 cm to greater than 500 cm), color, sediment type, sedimentary structures, x-ray mineralogy, and the ubiquitous presence of units in all abyssal plain and supplying canyon piston cores. In …
