Lithofacies Analysis Of The Roubidoux Formation, South Central Missouri, Michael William Harbaugh

Masters Theses

"Lithologic and thickness data of the Lower Ordovician rocks of the Roubidoux Formation, south central Missouri, were interpreted from sample logs. Maps included are based on structure, thickness and lateral and vertical lithologic variability. Sand distribution in the Roubidoux is represented by a "sand percentage" map, a "sand isolith" map, and a "tripartite sand distribution" map. The Roubidoux Formation consists of a sequence of dolomite, sandy dolomite, sand and chert. It is believed that the Roubidoux was deposited on a stable marine platform receiving a supply of elastics from the north and northeast. The sands were deposited by longshore or …

On The Wad-Minerals From The Cavern Environment, Naruhiko Kashima

International Journal of Speleology

The wad-minerals from limestone caves of Yugoslavia, China and Japan were studied. X-ray diffraction analysis revealed five minerals; birnessite, 10A-manganite, pyrolusite, todorokite and goethite. The heavy metal elements, Mn, Zn, Fe and Cr have been detected by X-ray fluorescence analysis and their contents were roughly determined. The condensation water introduced directly from the covering soils formed by the continental weathering and the deriving corrosive water interaction with limestone could be the input sources of manganese and other metal elements into the system.

Net Shore-Drift Of Thurston County, Washington, David M. Hatfield Jr.

WWU Graduate School Collection

Geomorphic and sedimentologic variations in coastal landforms were used to determine the direction of net shore-drift and delineate the boundaries of drift cells along 178 kilometers of the southern Puget Sound coast fronting Thurston County, Washington. The net shore-drift indicators used along the Thurston County coast were, in descending order of observed frequency, gradation in mean sediment size, beach width, foreshore offsets at drift obstructions, spit development, bluff morphology, beach slope, diversion of stream mouth outlets, plan view of deltas or intertidal fans, oblique bars, beach pads, and identifiable sediment.

Wind from the south-southwest prevails over Thurston County. Fetch is …

A Paleomagnetic Age Investigation Of Pre-Salmon Springs Drift Pleistocene Deposits In The Southern Puget Lowland, Washington, John L. (John Leo) Roland

WWU Graduate School Collection

The Pleistocene history of the southern Puget Lowland is marked by repeated invasions by the Puget Lobe of the Cordilleran ice sheet. The present stratigraphic sequence is represented by four glaciations (Orting, Stuck, Salmon Springs, and Fraser) of northern provenance, separated by unconformities and two nonglacial formations (Alderton and Puyallup) of central Cascade and Mount Rainier provenances. Paleomagnetic work conducted on pre-Salmon Springs sediments at their type localities and correlative exposures in the Puyallup Valley provide evidence for the ages of the Orting Drift, Alderton Formation, Stuck Drift, and Puyallup Formation.

The silts sampled demonstrate an array of soft (unconsolidated) …

Temporal Trends In The Geochemistry And Petrology Of The 1980 Mount St. Helens Pyroclastic Flow Deposits, Robert L. Logan

WWU Graduate School Collection

Petrographic and geochemical analyses were performed on pumice from the May 18, June 12, July 22, August 7, and October 16-18 pyroclastic flow deposits. The pumice is dacitic and contains, in order of decreasing abundance, the minerals plagioclase An_30-57, hypersthene, hornblende, magnetite-illmenite, ± augite, ± apatite, in a groundmass of highly vesiculated glass and plagioclase microlites. Vesiculation occurred over a period of about one second, but at times during the eruption probably within a zone in the vent rather than at the atmosphere-magma interface.

An increase with time in the crystal to glass ratio indicates continued cooling of …

Genesis Of Gold Deposits At The Little Squaw Mines, Chandalar Mining District, Alaska, Kathryn King Ashworth

WWU Graduate School Collection

The Little Squaw gold mines are located in the Chandalar Mining District, which is in the Brooks Range, 200 miles north of Fairbanks, Alaska. Country rock in the Little Squaw area consists of Devonian clastic and volcanic rocks which were subjected to two periods of upper greenschist facies metamorphism during the Cretaceous. A penetrative schistosity developed during the first metamorphic event, and thrust faulting and the development of a non-penetrative cleavage occurred during the second.

Gold-bearing quartz veins in the Little Squaw area crystallized along high angle normal faults which post date thrust faulting and cross-cut the non-penetrative cleavage. Data …

Geology Of The Park Butte-Loomis Mountain Area, Washington (Eastern Margin Of The Twin Sisters Dunite), David L. (David Lewis) Blackwell

WWU Graduate School Collection

Mappable units in the Park Butte-Loomis Mountain area of northwestern Washington are distinguished on the basis of age, lithologic association, structural position, and metamorphic recrystallization. There are four volcanic/volcaniclastic units: the Chilliwack Group, the Cultus Formation, the Elbow Lake-Haystack Mountain unit, and the Nooksack Group: and at least three allocthonous crystalline units: ultramafic rock (including the Twin Sisters and Goat Mountain dunite bodies), the Yellow Aster Complex, and the Vedder Complex. All units occur as tectonic fragments (fault bounded blocks) which are juxtaposed along anastomosing, horizontal to low angle, west dipping faults.

The upper Paleozoic Chilliwack Group is represented by …

Net Shore-Drift Of Mason County, Washington, Dana G. (Dana Genre) Blankenship

WWU Graduate School Collection

Winds from various directions cause waves which transport sediment along the shore. Over a relatively long time interval, sediment is moved in one predominant direction, which is the direction of net shore-drift. Variations in shoreline orientation cause shore drift to occur in discrete, essentially independent, drift cells.

By the specific identification of a number of established geomorphic and sedimentological shore drift indicators, drift cell boundaries can be delineated and the directions of net shore-drift determined. These indicators include changes in bluff morphology, beach width and slope, sediment-size gradation, identifiable sediment, deposition and/or erosion at shore drift obstructions, direction of spit …

Net Shore-Drift Of Pierce County, Washington, Brad D. Harp

WWU Graduate School Collection

The coastline of Pierce County, Washington, lies along the glacially scoured channels of Puget Sound. The highly crenelated coastline totals 373 km in length, with approximately 80 km contributed by five major islands and five minor islands. This study was conducted to determine the long-term net shore-drift along the Pierce County coast. Geomorphic and sedimentologic indicators were used to determine drift directions. These indicators include: direction of spit growth, change in bluff morphology and beach profile, stream diversion, sediment-size gradation, identifiable sediments (sediments from an identifiable source), and nearshore sand bar orientation. Sediment supplied to the foreshore is derived primarily …

On Determinism Versus Non-Determinism And Related Problems, Wolfgang J. Paul, Nicholas Pippenger, Endre Szemeredi, William T. Trotter

We show that, for multi-tape Turing machines, non-deterministic linear time is more deterministic Turing machines (that receive their input on their work tape) require time Q(n2) to powerful than deterministic linear time. We also recognize non-palindromes of length n (it is easy to discuss the prospects for extending this result to see that time O(n log n) is. sufficient for a more general Turing machines. non-deterministic machine). 1.

In Situ Studies Of Velocity In Fractured Crystalline Rocks, Daniel Moos, Mark D. Zoback

United States Geological Survey: Staff Publications

A study of the effects of macroscopic fractures on P and S wave velocities has been conducted in four wells drilled in granitic rock to depths between 0.6 and 1.2km. The effect of macroscopic fractures is to decrease both V_p, and V_s and increase V_p/V_s. In wells with a relatively low density of macroscopic fractures, the in situ velocitiys similar to that of saturated core samples under confining pressure in the laboratory, and there is a clear correlation between zones with macroscopic fractures and anomalously low velocities. In wells with numerous macroscopic fractures, …

United States Geological Survey: Staff Publications

Recent estimates of the magnitude and orientation of lithospheric stresses are
reviewed. Data come from a variety of sources including earthquake focal mechanisms, fault slip data, young volcanic dikes and feeders, in-situ stress measurements at depth, lithospheric flexure models, microstructure paleopiezometry, and consideration of constraints on maximum stress differences from laboratory-determined friction and flow laws.

Are There Any Shock-Heated Galaxies?, Gary J. Ferland, Hagai Netzer

Physics and Astronomy Faculty Publications

We study the spectroscopic characteristics of low ionization nuclear emission-line regions (Liners) in galaxies, and compare them with other active galactic nuclei. We show the results of new, extensive photoionization model calculations and use them to investigate line ratio diagrams, such as [O III] λ5007/Hβ versus [O II] λ3727/[O III] λ5007, and [O I] λ6300/[O III] λ5007 versus [O III] λ3727/[O III] λ5007. On the diagrams broad line objects, Seyfert 2 galaxies, and Liners form a continuous smooth sequence of decreasing ionization parameter. This suggests a common origin for line excitation in …

Protection Of Animals And Animal Experimentation: A Survey Of Scientific Experts, Norbert Lagoni, Joachim Fiebelkorn, Hans-Joachim Wormuth

Experimentation Collection

This article summarizes information from a survey of biomedical scientists, specifically pharmacologists and toxicologists, on the use of laboratory animals and the potential for replacing their use with alternative methods for the development and evaluation of pharmaceutical substances. The majority of those surveyed felt that the alternatives could supplement or complement animal tests, but not replace the tests altogether. However, most favored the use of nonsentient material in safety tests.

Dispersal And Harvest Of Sage Grouse Utilizing The Test Reactor Area Of The Idaho National Engineering Laboratory, Howard W. Browers, Jr.

Electronic Theses and Dissertations

A radio telemetry study of sage grouse (Centrocercus urophasianus) summering at the Test Reactor Area (TRA) on the Idaho National Engineering Laboratory (INEL) in southeastern Idaho was initiated in July 1980. Objectives included determination of habitat use, home range, brood breakup, fall movements, and harvest of sage grouse using the TRA. Supplemental habitat data and fall movement data were collected from sage grouse summering at the Central Facilities Area (CFA) on the INEL in 1982. Seasonal precipitation appeared to influence the period of use of the TRA by sage grouse. Grouse arrived later and left earlier in the wet year …

The Potential Role Of Local Ethical Committees In The Moderation Of Experiments On Animals In Britain, D. P. Britt

Experimentation Collection

Scientists working with laboratory animals in Britain are made aware forcibly that a serious ethical dilemma surrounds the use of animals in experiments. Certain vociferous sections of the community press the issue on the attention of the general public and media sources tend to propagate views expressed by the most extreme parties, while neglecting coverage of mature, rational opinion. It is, perhaps no bad thing for the scientific community to be frequently reminded to take a responsible attitude to the use of animals but recent overt, even illegal, activity on the part of extremist animal protectionist groups has encouraged a …

Chemical Composition Of Ground Water And The Locations Of Permeable Zones In The Yucca Mountain Area, Nevada, Larry Benson, J. H. Robison, R. K. Blankennagel, A. E. Ogard

United States Geological Survey: Publications

Ten wells in the Yucca Mountain area of southern Nevada have been sampled for chemical analysis. Samples were obtained during pumping of water from the entire well bore (composite sample) and in one instance by pumping water from a single isolated interval in well UE-25b#1. Sodium is the most abundant cation and bicarbonate the most abundant anion in all water samples. Although the general chemical compositions of individual samples are similar, there are significant differences in uncorrected carbon-14 age and in inorganic and stable-isotope composition. Flow surveys of seven wells performed using iodine-131 as a tracer indicate that ground-water production …

Intermediate-Band Photometry Of Stars In Three Clusters Containing Classical Cepheids, Edward G. Schmidt

Edward Schmidt Publications

Four-color and Hβ photometry has been carried out of stars in three sparse and distant clusters which are thought to contain Cepheids. From these data the distance moduli and color excesses of the clusters have been derived. In general the new values agree with those in the literature but are somewhat more precise.

Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

For the purposes of this book, the Northern Great Plains are defined as the states of Nebraska, North Dakota, and South Dakota. As a physiographic concept, the northern part of the great interior grasslands of North America is, of course, much broader in geographic extent than the Dakotas and Nebraska, but the three states lie in the heart of the region, and thus the title for this work seems appropriate. Our expectations in writing Mammals of the Northern Great Plains were to provide a comprehensive, yet semitechnical, treatmeat of free-living mammals that would prove useful to specialist and nonspecialist alike. …
