Biostratigraphy Of The Type Yamhill Formation, Polk County, Oregon, Larry R. Gaston

Dissertations and Theses

One hundred and seventy-four species and varieties of fossil Foraminifera are recorded from thirty-eight localities in the Siletz River Volcanics, Yamhill and Nestucca Formations exposed along Mill and Gooseneck Creeks, in the Northern Coast Range of Oregon. Marginulina holmesi is described as new. The Foraminifera indicate that this sequence was deposited during late Ulatisian and Narizian time, in marine waters at bathyal or lower neritic depths, with cool surface temperatures. The Yamhill Formation can be correlated with Moody Shale member of the Toledo Formation and the Coaledo Formation of Oregon; the McIntosh and Aldwell Formations of Washington; and the upper …

Barometric And Pump Test Determination Of The Characteristics Of A Carbonate Aquifer In The Vicinity Of Norman Creek, Phelps County, Missouri., Somchai Wongsawat

Masters Theses

"Carbonate rock aquifers underlie many parts of Missouri. As population and water use increase, these aquifers will increase in importance as sources of water supply. The purpose of this study is to investigate the applicability of barometric calculations and a variety of pump test evaluation equations to a shallow confined doloii mite aquifer. The aquifer is the upper Gasconade Formation of Lower Ordovician age in the vicinity of Norman Creek, south central Phelps County, Missouri.

The response of water level to atmospheric pressure showed that the carbonate aquifer in this study site has a rather high barometric efficiency (B_{av …}

An Analysis Of The Bourbeuse River As A Source Of Concrete Aggregate., David John Lexa

Masters Theses

"This thesis represents a study made to evaluate the sand and gravel deposits of the Bourbeuse River as a source of concrete aggregate. The Meramec River has long been a major source of aggregate in Missouri; however, proposed dam construction will limit the quantity available for exploitation. The Bourbeuse River, a tributary of the Meramec, was chosen for evaluation as an alternate source.

The study was conducted in two parts: an estimation of available quantity; a determination of the quality of the material. Quantity of material was estimated through an analysis of drill logs, correlated with the results of basic …

A Study Of The Subsurface Stratigraphy Of The Upper Cambrian In Western Missouri, Joseph L. Thacker Jr.

Masters Theses

"Megascopic examination of diamond-drill cores supplemented by insoluble residue data provides a usable means of studying the lithologic characteristic of Upper Cambrian strata in the subsurface of western Missouri.

The stratigraphic relationships within each Cambrian formation and the relationships of each Cambrian unit to formations above and below are discussed.

The relationship of Upper Cambrian strata to the Precambrian surface in western Missouri and easternmost Kansas is illustrated. The Lamotte Sandstone is overlapped by the Reagan Sandstone against Precambrian topographic highs and the Bonneterre and lower Davis are replaced by sandstones similar to the Reagan in southwest Missouri and southeast …

Interpretation Of Imagery Lineations, Logan Creek Area, Southeast Missouri, Gregory Paul Smith

Masters Theses

"Depletion of ore in Missouri's old lead districts and the opening of the state's new lead district adds impetus to understanding and delineating geologic structure in and adjacent to the new lead district. Image and geomorphic analysis, hydrologic data, and subsurface structural contour mapping are used in interpretation of geologic structure in Dent, Shannon, Reynolds, and Carter counties, Missouri. Unlike the time consuming surface geologic mapping, the modes of investigation used in this study enabled the writer to make a larger, regional-scale study with results comparable to those attainable by surface mapping. The area is covered by thick residual soils …

A Mechanical Well Log Study Of The Popular Interval Of The Mississippian Madison Formation In North Dakota, C. W. Cook

Theses and Dissertations

The Poplar interval of interbedded evaporites and carbonates forms the uppermost part of the Mississippian Madison Forr.1ation in western North Dakota. A detailed mechanical well log study of the Poplar interval in North Dakota was conducted to interpret the Poplar's regional geology and to attempt to locate areas with potential for petroleum production. Limestone, dolomite, anhydrite and salt were differentiated using mechanical well logs.

The complex facies of the Madison are subdivided into para-time rock units (the Poplar interval is one) on the basis of extensive thin anhydrite beds which are considered time-parallel.

The base of the Poplar interval is …

Evolution Of Platt Shoals Northern North Carolina Shelf: Inferences From Areal Geology, Philip C. Sears

OES Theses and Dissertations

The evolution of Platt Shoals, a complex ridge and trough system on the south side of the Albemarle Shelf Valley, was determined and the modern hydraulic regime was inferred. The methods used were surficial grain size, 11 vibracores, seismic profiling and bathymetric maps. Platt Shoals developed in a three step process. The first, step was the formation of a substrate of late Pleistocene regressive deposits from 15,000 to 30,000 yr B. P. The second step, occurring approximately 11,000 yr B. P., was the formation of estuary mouth shoals of the ancestral Albemarle River. Between 4,4.00 to 5,000 yr B. P., …

Geology Of The East Fork Mine And Vicinity, Sevier County, Tennessee, John Charles Brower

Masters Theses

The East Fork mine consists of a series of open cuts in steeply dipping low-grade metasediments of the Late Precambrian (?) Ocoee Series. In general the metasedimentary units strike northeast and dip steeply to the southeast. However, interpretation of stratigraphy and structure is complicated by intensive local folding and faulting. Two large thrust faults occur in the southern part of the study area, and two or more thrust sheets comprise the bulk of Dixon Mountain in the eastern part of the study area. At the southern boundary of the study area, the Dunn Creek fault thrusts rocks of the Snowbird …

Granulometric Analysis Of Recent Sediments Of Tillamook Bay, Oregon, Gennaro William Avolio

Dissertations and Theses

The author has sampled the recent bottom sediments in Tillamook Bay, Oregon. Sediment distribution is assessed in relation to sediment source areas and related to sedimentary environments. Particular attention was directed to the precision with which granulometric data can be stated. It was found that variance is quite high for granulometric parameters of the bay sediments.

Sediment distribution using different measures are displayed on charts of the bay. Size distributions of sediments at any given location are examined for geologic significance. Plotting of size distribution on graph paper using probability ordinate is shown to increase the ease of geologic interpretation. …

A Tectonic Study Of A Part Of The Northern Eagle Cap Wilderness Area, Northeastern Oregon, Kenneth Gordon Neal

Dissertations and Theses

Upper Triassic metavolcanic and metasedimentary strata in the study area are intruded by the Hurricane Divide and Craig Mountain Plutons of the Late Jurassic-Cretaceous Wallowa Batholith. The Clover Creek Greenstone is overlain by the Martin Bridge Limestone, which is in tum overlain by the Hurwal Argillite; although the sequence is in normal stratigraphic order, contacts are generally tectonic. Concurrent with Early-Middle Jurassic regional deformation, during intermediate to mafic dikes, emplacement of the plutons of the Wallowa Batholith began. The plutons intruded vertically through the greenstone and limestone and then horizontally above the greenstone. This resulted in intense penetrative plastic deformation …

A Test Of The Non-Uniform Distribution Of Azimuths Of Overlapping Lunar Craters, John Richard Dickson

Earth and Planetary Sciences ETDs

The azimuths between the centers of overlapping lunar craters show a statistically strong preferred orientation over most of the lunar globe for those crater pairs where the younger crater is of relatively small diameter (10-25 km). A strong north-south preferred lineation also exists in a narrow belt along the east and northern limb of the full moon for those crater pairs involving relatively large diameter craters (45 km). Various endogenic and exogenic mechanisms which might create a preferred orientation of overlapping craters are considered in the light of these findings. The preferred orientation of the smaller craters could result from …

Chemical Quality Of The Groundwater System In Hall County, Nebraska, Jon C. Atkinson

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Hall County, an area of 540 square miles, is in south-central Nebraska. The Platte River flows east-northeasterly across the county from its southwest corner; the Wood River, which is tributary to the Platte within Hall County, enters the county about 6 miles north of the southwest corner. Analysis of streamflow data indicates that the Platte and Wood Rivers are losing streams in Hall County. Based on an 18-year period, October 1953 through September 1971, the average annual losses between gaging stations were 48,100 and 1,940 acre-feet, respectively.

The county is underlain by unconsolidated deposits of Quaternary age. These deposits mantle …
