The Michigan Basin, L. L. Sloss

UMR Journal -- V. H. McNutt Colloquium Series

The Michigan basin is widely acknowledged to be the archetype among those basins of cratonic interiors whose subsidence is dominated by flexure rather than faulting. Broadly ovate in plan over an area of some hundreds of thousands of square kilometers, with a preserved Phanerozoic sediment thickness exceeding 4 km accumulated during distinct episodes of subsidence over a 500-million year span, the basin is endowed with significant fossil-fuel resources.

The basin area is crossed, from north-northwest, by a rift zone filled with mafic igneous rock and great thickness of sedimentary rock resting on Archean and Middle Proterozoic crystallines. Rifting is presumably …

Geology And Energy Resources Of The Arkoma Basin, Oklahoma And Arkansas, Boyd R. Haley

UMR Journal -- V. H. McNutt Colloquium Series

The Arkoma basin is a structurally defined basin that underlies an area of about 13,000 sq. mi. It extends from Little Rock, Arkansas, to Atoka, Oklahoma. The rocks in the basin grade upward from dolomite, some limestone, sandstone (Upper Cambrian to Upper Devonian) to shale and limestone (Upper Devonian to Lower Pennsylvanian) to shale, limestone, and sandstone (Lower Pennsylvanian) to shale and sandstone (Middle Pennsylvanian). The sediments that formed rocks in the lower part of the Atoka formation on the south side of the basin were deposited in a deep-water environment. All other sediments in the basin were deposited in …

Basement Rocks Of The Main Interior Basins Of The Midcontinent, Edward C. Lidiak

UMR Journal -- V. H. McNutt Colloquium Series

The basement underlying the deeper basins in the Midcontinent is not well known because of the considerable thickness of overlying sedimentary rocks. However, gravity and magnetic surveys and sparse wells to basement suggest that deeper intracratonic basins are characteristically underlain by denser and more magnetic rocks than in adjacent areas. This correlation has important bearing on understanding the tectonic development and geologic history of Midcontinent basins.

The Michigan basin is underlain by prominent, linear gravity and magnetic highs that extend across the southern peninsula. A recent deep well to basement encountered basalt overlain by red clastic sedimentary rock. The combined …

Geologic-Tectonic History Of The Area Surrounding The Northern End Of The Mississippi Embayment, H. R. Schwalb

UMR Journal -- V. H. McNutt Colloquium Series

Since Precambrian time, zones of weakness have been repeatedly but infrequently reactivated in the Mississippi Embayment area. All of the major folds and many of the minor anticlines caused by this activity are associated with faults in the basement rocks. The latest occurrence of major tectonic activity (perhaps Early Cretaceous), however, not only affected the old fault zones but also created a vast new feature, the Pascola arch, which has no Paleozoic antecedent. Severe erosion and subsequent Tertiary subsidence associated with the Pascola arch indicate that this structure alone is the locus of present-day major earthquake activity. Until the time …

Structure Of The Salina-Forest City Interbasin Boundary From Seismic Studies, Don W. Steeples

UMR Journal -- V. H. McNutt Colloquium Series

As petroleum exploration efforts in the Midcontinent become directed toward smaller fields and the search for minerals is extended into new areas, the edges of the Salina and Forest City basins will become of increased interest to industry. The principal boundary feature between the two basins is the Nemaha ridge, a linear feature that extends from near Omaha, Nebraska, to near Oklahoma City, Oklahoma. Recent seismic studies at the Kansas Geological Survey have revealed a complex array of faulted and folded structures in the vicinity of the Humboldt fault zone (the eastern flank of the Nemaha ridge). Faulting of both …

Geological Evolution And Energy Resources Of The Williston Basin, Lee C. Gerhard

UMR Journal -- V. H. McNutt Colloquium Series

The Williston basin of North Dakota, Montana, South Dakota, and south-central Canada (Manitoba and Saskatchewan) is a major producer of oil and gas, lignite, and potash. Located on the western periphery of the Phanerozoic North American craton, the Williston basin has undergone only relatively mild tectonic distortion during Phanerozoic time. This distortion is largely related to movement of Precambrian basement blocks.

Sedimentary rocks of cratonic sequences Sauk through Tejas are present in the basin. Sauk, Tippecanoe, and Kaskaskia Sequence rocks are largely carbonate, as are the major oil and gas producing formations. Absaroka and Zuni rocks have more clastic content, …

Preface, Paul Dean Proctor, John W. Koenig

UMR Journal -- V. H. McNutt Colloquium Series

The UMR Journal has had an interesting but somewhat sporadic history. The topics of papers that appeared in UMR Journal 1 in 1968 under the general title of “A Coast to Coast Tectonic Study of the United States” covered the major tectonic features of the contiguous United States from the margin of the Atlantic continental shelf to the Pacific coast. Each paper was authored by a recognized expert for the specific province reviewed. UMR Journal 2, which was published in 1971, related to “Alaska—Its Mineral Potentials and Environmental Challenges”. This UMR Journal 3 emphasizes the geology, genesis, and energy resources …

Isotope Effect In Electron-Capture Differential Cross Sections At Intermediate Energies, Eduard P. Rille, Ronald E. Olson, Jerry Peacher, D. M. Blankenship, Thomas J. Kvale, E. Redd, John T. Park

Physics Faculty Research & Creative Works

The isotope dependence in the angular distribution of electron-capture cross sections for protons and deuterons with equal velocity (E=40 keV/u) colliding with atomic hydrogen or deuterium targets is predicted theoretically and observed experimentally. A projectile-dependent effect is observed at small scattering angles. No target dependence was detected in the differential cross sections. A scaling relationship is determined which permits the prediction of differential cross sections for hydrogen-isotope projectiles.

Measurement Of Spin-Exchange Effects In Electronhydrogen Collisions: Further Studies Of Impact Ionization, Timothy J. Gay, G. D. Fletcher, M. J. Alguard, V. W. Hughes, P. F. Wainwright, M. S. Lubell

Timothy J. Gay Publications

Using a Fano-effect polarized electron source and a state-selected thermally dissociated hydrogen beam, we measured the interference between the direct and exchange scattering amplitudes for electron-impact ionization of atomic hydrogen between 14.1 and 30.3 eV. We report the data from these measurements and the results of corrections applied to previously published data.

The Origin Of Carbonate Cements In Bahama Escarpment Limestones, Katharine D. Fulker

Masters Theses

Limestones recovered from Bahama Escarpment dives (DSRV Alvin, 1978) were expected to contain shallow marine, freshwater, and deep marine cementation since the limestones had been fractured, bored, and cemented at depth. Magnesium and trace element concentrations, carbon-oxygen composition, cathodoluminescence, and petrographic study indicated the presence of all three cement types.

Lithification may have proceeded by allochem deposition, major shallow marine cementation, sparse freshwater cementation leaving porosity, fracturing, and final deep marine cementation leaving minor porosity. According to this interpretation, the pore space remained open for an unlikely 75-115 million years. In an alternative interpretation, pore space is occluded after freshwater …

Pennsylvanian Deltaic Sedimentation In Grand Ledge, Michigan, Jeffrey R. Martin

Masters Theses

Pennsylvanian outcrops along the Michigan Basin's southern/margin are composed of fluvial-deltaic and marine shelf sediments. Constructive deltaic facies include point-bar sandstones displaying erosional bases, channel lag, and upward decreasing grain size and sedimentary structures. Cross-stratification data indicate a unimodal, highly variant, northward-trending, paleocurrent pattern that deviates from regional paleoslope. Point-bar sandstones record delta plain deposition by meandering distributary channels. Channel margin facies include Lingula-bearing, interdistributary bay shales; overlain gradationally by laminated, flaser-bedded and rooted marsh shales and siltstones; and subbituminous swamp coal. Bay-fill facies are interrupted by lens-shaped, quartz-poor, fine-grained, crevasse-- splay sandstones.

Delta destructive facies--quartz -rich bioturbated sandstone-- suggest …

Kinetic And Spectral Studies Of Cobalt (Ii) -4, 4’, 4’’, 4’’’ –Tetrasulfophthalocyanine With Sodium Cyanide In Aqueous Solution, Pablo J. Diaz Cruz

Masters Theses & Specialist Projects

Kinetic studies of the cobalt (II)-4, 4’, 4’’, 4’’’-tetrasulfophtalocyanine and cyanide system were performed under argon and in air over temperature ranges of 294-314°K and 294-324°K, respectively. Two reactions were detected under argon. One was quite rapid and was followed on the stopped-flow apparatus. The results are consistent with the perturbation of a monomer-dimer equilibrium. The second reaction was slow enough to be followed spectrophotometrically on the Cary Model 14 spectrophotometer. The second order rate constant of 0.11 M^-1 sec^-1 at 294°K has been attributed to the rate of substitution of the second cyanide addition to a dye-cyanide …

Oxidation Activity Of Catalyst 3-7a Toward Formaldehyde, Hydrogen Cyanide, And Some Alkane Gases, John Kawas

Masters Theses & Specialist Projects

The activity of Catalyst 3-7A toward the oxidation of formaldehyde, hydrogen cyanide, methane, propane, and isobutene was examined at temperatures between 25°C and 400°C. The catalyst consists of palladium(II) and copper (II) salts impregnated on an alumina support. The oxidation measurements were made primarily with gas chromatographs, although form aldehyde and hydrogen cyanide were also examined using the colorimetric fushsin method and Liebig titrations, respectively. Catalyst 3-7A demonstrated appreciable activity toward the oxidation of all gases studied except formaldehyde where there was no evidence of oxidation. The latter result is quite unexpected since aldehydes are more easily oxidized than alkanes. …

Progress Report On Effects Of Contour Banking On Surface Runoff At The Berkshire Valley Experimental Catchment (Near Moora) 1961-82, K J. Bligh

Resource management technical reports

The time lag prior to peak runoff following rains of comparable high intensity increased by approximately 80 per cent in the largest event after the construction of contour banks. Although 80 per cent more runoff also occurred because the catchment was wetter and had been cultivated for three years in a row, the peak rate of runoff increased by only approximately 20 per cent. That the peak rate was not increased by 80 per cent, may be primarily attirbuted to the effect of the contour banks.

The Effect Of Fetal Age On Skin Permeability In Guinea Pigs, Benita Stiles Whitted

Loma Linda University Electronic Theses, Dissertations & Projects

Preliminary investigation has indicated large decreases in fetal skin permeability during the latter half of gestation (Parmley and Seeds, 1970; Treager, 1966). The purpose of this study was to demonstrate the degree of skin permeability in fetal guinea pigs at various gestational stages. The test hypothesis was that these skins would show a significant decrease in permeability to tritiated water when tested at time increments through out the latter half of gestation.

In vitro skin permeability to tritiated water was measured in samples from 22 guinea pig fetuses. Gestational age ranged from 30 to 65 days in increments of five, …

The Geology And Origin Of The Sawyer Uranium Prospect, Live Oak County, Texas, Charles L. Brewster

Masters Theses

The Sawyer uranium prospect is a subsurface uranium occurrence hosted within the basal Oligocene Catahoula Formation of the Texas coastal plain. The host rocks consist of tuff-ball conglomerate, tuffaceous sandstone and tuffaceous claystone whose geometry and lithological characteristics indicate that they are the products of a crevasse-splay depositional environment. Compositionally, these lithologies are feldspar-depleted litharenites, with the feldspar depletion due to the corrosive, ore-forming processes. These sediments display pedogenic to early diagenetic features including diffuse to discrete micrite nodules, clay cutans, fresh to partially argillized glass shards, clay booklets, authigenic zeolites and sulfides, paleosoil horizons and calcite cement.

Electron Capture And Ionisation In H⁺, He2++Li Collisions, Ronald E. Olson

Physics Faculty Research & Creative Works

Single electron capture and ionization cross sections have been calculated for H++Li and He2++Li collisions at energies ranging from 50 to 400 keV amu-1. Double electrons capture cross sections are presented for the He2++Li system. The classical-trajectory Monte Carlo method and the independent-electron model were used to calculate the cross sections. In the energy range investigated, the ionization process is dominated by electron removal of the valence Li(2s) electron, whereas the single and double electron capture processes are the result of capture from the K shell of the lithium atom.

On The Ising Model For Amorphous Ferromagnets, Harry A. Brown

Physics Faculty Research & Creative Works

A calculation is made of the effect on the critical temperature of a ferromagnet whose exchange integrals are taken to be random variables. The Bethe-Peierls-Weiss approximation is used to find the partition function, Z, for an Ising system and then a configuration average is taken to find (InZ), from which the resulting decrease in the critical temperature can be found. Other results are discussed, and comparisons made with the present result.

Nonlinear Anelasticity Of Magnesium, Alexander Aning, Tetsuro Suzuki, Manfred Wuttig

Physics Faculty Research & Creative Works

An approximate solution of the equation of motion of a nonlinear anelastic reed at or near resonance is presented. The steady state solution reproduces the well-known nonlinear resonances. The solution also predicts the existence of auto modulations, i.e., self-excited modulations of the amplitude and phase at constant power of excitation of the reed. Numerical examples of such auto modulations are presented for an antisymmetric deformation potential. Experimental studies of finite amplitude oscillations of a magnesium reed vibrating at 72 and 431 Hz at room temperature confirm the existence of auto modulations. The experimental results can be semi quantitatively described in …

Angular Scattering In Slow Multiple-Charged Ion, Atom Collisions, Ronald E. Olson, M. Kimura

Physics Faculty Research & Creative Works

The C6++H system is used to illustrate the importance of large-angle scattering in collisions between slow multiply charged ions and atoms. A quantum mechanical description based on a diabatic formalism of the collision system is used to obtain differential cross sections for electron capture in the relative velocity range nu =1*107 to 3*107 cm s-1 (Ecm approximately=48 to 430 eV). The threshold for angular scattering is at E theta approximately=0.2 keV deg which correlates with the curve crossing between initial and final molecular states located at Rx approximately=8a0. The centre-of-mass acceptance angles required to observe fixed fractions of the total …

Determination Of Organophosphorus Compounds By Hplc With Post-Column Photochemical Degradation Followed By The Formation Of Reduced Heieropolymolybdate, Stephen R. Priebe

Dissertations

A novel method for the determination of organophosphorus (OP) compounds by HPLC with post-column photochemical and chemical derivatization reactions has been developed. The OP compounds eluted from the column were photochemically degraded to orthophosphate by the use of a 450 W xenon lamp in conjunction with an auxiliary photodegradation reagent. The photodegradation reaction was studied extensively by means of batch irradiations with triethylphosphate as a model compound. The effects of the initial concentrations of triethylphosphate and ammonium peroxydisulfate, and of varying the pH of the reaction medium were determined. A survey of potential interferences was performed. Copper(II) ion was found …

Kinetics Of Ternary Complex Formation Reactions Of The Nickel(Ii) Complexes Of Ethylenediaminediacetate And Triethylenetetramine With Bidentate Donors, Lawrence H. Kolopajlo

Dissertations

The stopped-flow technique was used to measure rate constants for ternary complex formation involving both NiEDDA and Ni(trien)('2+), and bidentate donors. The reactions of both NiEDDA and Ni(trien)('2+) with bipy, phen, en, and sar were studied. In addition the reaction of NiEDDA and gly was studied. The reactions were of the first-order with respect to either nickel complex, and with respect to enH('+), bipy, and phen. The reactions involving phen and bipy were independent of pH and were reversible. The formation rate constants for the systems containing diamine reactants are as follows:

Seasat Orbital Radar Imagery Applied To Lineament Analysis And Relationships With Hydrocarbon Production In The Wartburg Basin Area, Tennessee, S. E. A. Brite

Masters Theses

Seasat, an orbital synthetic aperature radar launched in 1978, has produced high-resolution imagery enhancing over 1186 observed linear topographic indentations or lineaments in the Wartburg Basin area of east-central Tennessee. The main objectives of this thesis are to verify these lineaments in the field, to compare them with aerial photographic lineaments in the same area, to statistically analyze lineament trends, and to compare lineaments with oil and gas trends in the Wartburg Basin area.

Lineaments from Seasat imagery were located in the field with a high degree of accuracy. Three distinct lineament systems were derived from lineament orientations, their grouping …

The Mystery Of The Missing Boundary Layer, Gary J. Ferland, S. S. Langer, J. Macdonald, G. H. Pepper, G. Shaviv, J. W. Truran

Physics and Astronomy Faculty Publications

The question of the nature of the ultraviolet and X-ray radiation field of cataclysmic binaries is addressed. The spectrum and luminosity of this radiation are important in determining the mass transfer rate and energy budget of the system and in studies of the ejecta surrounding novae. In many systems, the soft X-ray luminosity is ~ 10²-10⁴ times weaker than predicted by simple accretion models. We discuss several possible solutions to this discrepancy. The most likely are either that the optical luminosity of a typical old nova is produced partly by reprocessed ultraviolet light from the white dwarf, …
