A Mathematical Study Of Voigt Viscoelastic Love Wave Propagation, David Nuse Peacock

Masters Theses

"This research is a mathematical investigation of the propagation of a Love wave in a Voigt viscoelastic medium. A solution to the partial differential equation of motion is assumed and is shown to satisfy the three necessary boundary conditions. Velocity restrictions on the wave and the media are developed and are shown to be of the same form as those governing the elastic Love wave"--Abstract, page ii.

Tectonic Analysis Of Mare Humorum On The Lunar Surface, Adnan Said Abul-Husn

Masters Theses

"Morphology and internal structures of surface features of the Mare Humorum area were interpreted from photographs and topographic maps. The postulated origin of certain features is based on analog comparisons with known terrestrial features. The laws of crate ring and a newly developed computer program were applied to two representative classes of craters to determine the possibility of a meteoritic impact origin. Some of the craters formed by meteoritic impact and others, including those with a radius larger than 10 Km, probably resulted from volcanic activity.

Mare Humorum formed from centripetal subsidence followed by extensive lava eruptions. Spacially related rilles …

Two-Dimensional Seismic Model Studies, Joong Hee Chun

Masters Theses

"The purpose of this research was to design and construct apparatus suitable for two-dimensional seismic model studies.

A new technique for two-dimensional seismic model testing was devised which allows wide application of the equipment. This enabled the author to place the source and receiver in any desired position on the model, thereby permitting the recording of seismic events as function of distance and depth at any position

Two simple geometric models were tested to demonstrate the experimental range of the apparatus designed. The recorded data were compared with theoretical predictions and were found to be in good agreement"--Abstract, page ii.

Origin And Factors Affecting Distribution Of Solid Oil In Mid-Western Missouri, Rafid Abdul-Halim Jasim

Masters Theses

"A textural analysis was made of the heavy oil-bearing sandstones in the Middle Pennsylvanian (Desmoinesian) Warner and Bluejacket formations of mid-western Missouri in order to determine and compare their depositional environments.

Grains of the Bluejacket sandstones are smaller and more rounded than grains of the Warner sandstones. The Bluejacket sandstone is also better sorted than the Warner sandstone.

The Bluejacket sandstone is thin-bedded; the Warner is mostly massive-bedded. These differences in bedding between the two formations have affected distribution of oil in the area of study.

Both the Bluejacket and Warner sandstones are better sorted than the Warrensburg sandstones; the …

Geology Of The Acari Iron Mining District Arequipa, Peru, Raul Alejandro Zevallos

Masters Theses

"The Acari Iron Mining District, part of a tilted uplifted fault block, comprises an area about 300 square kilometers, in the southern part of the coastal belt of Peru. It is in the foothills of the western range of the Andes and it is dominantly formed by granodioritic and granitic intrusive rocks which belong to the Andean batholith of Cretaceous-Tertiary age. The intrusive rocks are overlain by a central, elongated, northwest trending band, of metasedimentary and volcanic rocks

The magnetite deposits of Acari district are long, dike-shaped bodies, which fill two systems of fractures in the granodiorite intrusive, located in …

Ecology And Distribution Of Foraminifers Of A Traverse In The Northwestern Gulf Of Mexico, Faiz Nassir Thomas

Masters Theses

"Foraminiferal populations have been analyzed from five bottom samples along a traverse in the northwestern Gulf of Mexico, approximately 27⁰20' to 97⁰15' north latitude and 97⁰20' to 97⁰05' west longitude. Eighty-eight species and twenty-nine genera, belonging to eighteen families, were recorded. Species were identified and described.

Statistical studies indicate that probably five benthonic foraminiferal depth facies could be recognized in the area at the following approximate depths: 4 fathoms, 4-8 fathoms, 8-12 fathoms, 12-16 fathoms, and 16-20 fathoms. Determination of facies is based largely on the range of species. The frequency distribution of species of foraminifers was plotted against change …

Heat Flow In The Boss Deposit Of Missouri, Don Stainbrook

Masters Theses

"Values of heat flow through a Precambrian mineral deposit were determined in the Boss area of Missouri, where 350 meters of Paleozoic sedimentary rocks overlie a complex series of rhyolite flows which have been altered and contain a copper bearing magnetite deposit. Geothermal data were obtained from a closely spaced grid of 17 diamond drill holes penetrating to depths of 1000 meters below ground surface. Temperature measurements were made at 5 meter intervals in the Precambrian section of all holes. These and thermal conductivity measurements made on representative core samples from 300 to 400 meters below the top of the …

Structure Contours On The Top And Base Of The M Bed, The Relationship Of Mineralization To Structures, And The Variation Of The M Bed Thickness In The Tri-State District, Missouri, Kansas And Oklahoma, Arvind A. Desai

Masters Theses

"Regional structure and thickness of a single horizon, the M bed, have been studied in the Tri-State district by picking the top and base of the M bed in the logs of 557 selected drill holes and contouring this data together with the aid of local detailed structural information available for individual mining fields. Structures determined from these data were compared to the positions of mined mineralization to determine the control of regional structure upon the localization of ore. Variations in the M bed thickness were compared to the positions of fields of mineralization to examine possible spatial relationships which …

Upper Cretaceous-Lower Cenozoic Foraminifera From An Oil Well In Northwestern Iraq, Farouk Sunallah Al-Omari

Masters Theses

"Twenty-five samples of well cuttings from the Iraq Petroleum Company Butmah Number 9 Well in northwestern Iraq, at approximately 36° 37' north latitude and 42° 41' east longitude, have been examined in detail. The boundary between the Upper Cretaceous and lower Cenozoic is recorded as closely as possible on the basis of the microfaunal assembalges. A unit showing equivalence to the Danian Stage also is recognized"--Abstract, page ii.
