Petrography Of The Midale Subinterval In The Bottineau And Renville Counties Area, North Dakota, Morris J. Mccollum

Theses and Dissertations

About 250 thin sections of core samples from the Midale subinterval in the Bottineau-Renville Counties area of North Dakota (T161N-T164N and R78W-R86W) were studied petrographically. The Midale subinterval is the basal section of the Ratcliffe interval of the Madison Group of Mississippian age. In the area of study it is composed of interbedded fine grained limestones, pelletiferous and oolitic limestones, and primary anhydrite. Dolomitization of the limestones in varying stages is common and the dolomitized limestones are usually fine grained. Course crystals of secondary anhydrite are common as vug and fracture filling and as a replacement of the carbonates.

Syntheses And X-Ray Investigations Within The System Fes₂-Cos₂, Samuel Shu Mou Chan

Masters Theses

"Pyrite (FeS₂), cattierite (CoS₂), and various transitional members of the solid solution compounds were prepared. The methods used are as follows:

First, sulfides of cobalt, iron, or cobalt-iron were obtained by precipitation from a mixture of the cobalt chloride and/or ferrous sulfate in an aqueous solution. The dried precipitates were then mixed with an equal weight amount of sulfur and placed into silica glass tubes. After evacuation, they were filled with hydrogen gas of 3/4 of atmospheric pressure and sealed. The samples were then heated up to 500°C (for FeS₂), 650°C (for FeS_{2 …}

Geology Of The Esterbrook Area, Converse And Albany Counties, Wyoming, Michael Nolan Greeley

Masters Theses

"The Esterbrook area lies within the Laramie Range in Converse and Albany Counties, Wyoming. Exposures include Precambrian metamorphic and igneous rocks, the Tertiary White River formation, and Quaternary alluvium.

Hornblende schist and mica-quartz schist comprise the Precambrian metamorphic rocks. Foliation planes of these rocks trend northeast and dip steeply to the southeast. Metamorphic rocks of younger age probably lie to the southeast.

A distinctive, Precambrian silicic pluton of biotite-leucogranite with marginal zones of muscovite-leucogranite and alaskite passively intrudes the metamorphic rocks, generally parallel to the foliation trends. Numerous granite pegmatites show a zonal distribution around the pluton and appear to …

Application Of Digital Computer To Magnetic Data Interpretation Using Surface Integral Method, Afif Hani Saad

Masters Theses

"A simple method is developed for the calculation of the magnetic effect due to three-dimensional bodies. The method is based on the use of surface integration instead of volume integration. Thus, any three-dimensional body can be considered as having two surfaces, upper and lower, with magnetic pole distributions. Simple equations based on potential theory have been derived for the calculation of the vertical component and total intensity due to these surface distributions of poles. The anomalous field of the body can be obtained by subtracting the effect due to one of the surfaces from that of the other.

The method …

Foraminifera Of The Cenozoic And Recent Genus Sphaerogypsina Galloway, Wayne C. Horton

Masters Theses

"The morphology of Sphaerogypsina as seen in thin section affords various characters useful in classification] 1) arrangement and composition of the wall (calcareous-perforate, radially crystalline); 2) layering of wall (like Gypsina, without layering or black line, having only microlamellae); 3) shape of test (always spherical); and 4) specific characters: size of test, order/unorder ratio, size of chambers, wall thickness, pore diameter, and type of embryonic apparatus.

Correlation of the above characters has allowed recognition of two new species. Comparisons with other genera strongly suggest placing the genus in the Family Gypsinidae (nom. correct.) rather than in the …

Seismic Investigation Of Flint Clay Deposits In East Central Missouri, Roland D. Dayley

Masters Theses

"Seismic refraction surveys were conducted in several localities within the east central Missouri clay districts in order to determine the applicability and economy of this method as a clay exploration tool. Results of these surveys revealed that the sink-type clay deposits possess lithologic and structural characteristics that lend themselves favorably to this method of exploration.

Seismic records obtained from profiles shot across known deposits indicate that several factors other than velocity contrast serve to produce apparent seismic anomalies.

Some unforeseen time loss and expense was encountered because of malfunctions of the seismic equipment employed, which necessitated the purchase and installation …

Study Of The Copper-Uranium Deposits At Vilcabamba, Department Of Cuzco, Peru, Oscar Aguilar

Masters Theses

"Uranium has been known in the Vilcabamba district of Cuzco, Peru since 1954. Copper ores of high silver content were worked by the Spaniards during the seventeenth and the early eighteenth centuries, At the beginning of the twentieth century these ores were worked intermittently; during the last fifty years no mining operation has been going on.

The oldest rocks in the thesis area consist of Ordovician phyllites. The presence of Devonian in the area is questionable, but has been recognized 5 km. away from the thesis area. A conglomerate of limited lateral extent of Mississippian age overlies the Devonian (?) …

Investigation And Development Of Ground Water Of Chalone Creek, (Pinnacles National Monument, California), Donald Lee Brown

Masters Theses

"The Pinnacles National Monument is located in San Benito and Monterey Counties about 130 highway miles south of San Francisco, California. Because of unusual patterns in volcanic rocks, the Monument was set aside as a recreation area on January 16, 1908, by President Theodore Roosevelt. It encompasses an area of approximately 12,818 acres.

Water quality and supply problems were experienced at the Monument in the few years prior to 1961. In 1961, a collection trench system was installed to alleviate the water supply condition. A horizontal trench system, 215 feet long and four feet below the dry season water table, …

Ground Water Investigation In The Southern Half Of Franklin County, Missouri, Kemal Piskin

Masters Theses

"Increasing population and industrialization in Franklin County, Missouri, has led to increased demand for water. Much of this demand will be satisfied from ground water resources. Although the general geology of Franklin County has been mentioned in several publications, no detailed study of structure and ground water geology had been done. This thesis consists of study of stratigraphy, lithology, and geologic structure, and analysis of well log data to determine occurrence and availability of ground water, in the southern half of Franklin County.

Stratigraphy and lithology is compiled from previous literature, modified to agree with well log data. Structural geology …

A Study Of Placer Tin Materials From Southern Thailand, Somkiat Ganthavee

Masters Theses

"This thesis deals with a series of investigations of placer tin samples from a Chinteik's Tin-dredge, Gnaw District, Ranong Province, and the Tin-Pet mine, Phang-gna Province, in southern Thailand.

A brief summary of the geography and geology of Thailand as a whole has been given as a general introduction to the source of the materials studied in this thesis.

The results of sieve analyses have shown that the sluice boxes do not effectively concentrate the cassiterite grain below 0.147 mm. from the rough concentrate treated in the tin-dressing shed.

It has been found that roundness and shape determinations of quartz …
